Description of Embodiments
[0027]
Hereinafter, preferred embodiments of the present
invention will be described with reference to the drawings.
[0028]
<First Embodiment>
Fig. 1 is a schematic diagram showing an example of a
configuration of a device for producing fuel 1 according to
the present embodiment. In the device for producing fuel 1
of the present embodiment, for example, a biomass raw
material cutting process, a washing process, and a
compression molding process are performed in succession in
this order to produce solid fuel.
[0029]
In the present specification, the biomass raw material
(also simply referred to as a "raw material") includes a
wood-based biomass raw material that includes a plant such
as sorghum, napier grass, or oil palm empty fruit bunches,
and a waste-based biomass raw material that includes waste such as garbage. Further, a material before cutting, after cutting, or after washing is referred to as a raw material, and a material after compression molding is referred to as fuel.
[00301
For example, the device for producing fuel 1 includes
a cutting device 10 that cuts a biomass raw material to a
size larger than powder, a washing device 11 that washes
the cut raw material with water, a compression molding
device 12 that molds fuel by compressing the raw material
to which the washing water has adhered, a first transport
unit 13 that transports the raw material cut by the cutting
device 10 to the washing device 11, and a second transport
unit 14 that transports the raw material washed by the
washing device 11 to the compression molding device 12.
[0031]
The cutting device 10 is for roughly cutting the
biomass raw material to a size of 10 mm or larger and 50 mm
or smaller. For example, a crusher having a single-stage
cutter may be used for the cutting device 10. For example,
the cutting device 10 includes a hopper 20 having a
substantially cylindrical shape or a substantially square
tube shape whose center axis is directed in an up-down
direction, an input part 21 which is provided at an upper
portion of the hopper 20 and into which a raw material Is input, a discharge part 22 provided at a lower portion of the hopper 20 to discharge the raw material, and a single stage cutter 23 provided between the input part 21 and the discharge part 22 to cut the raw material. The cutting device 10 can cut the biomass raw material input from the input part 21 of the hopper 20 to a size of 10 mm or larger and 50 mm or smaller by the single-stage cutter 23 and discharge the cut raw material from the discharge part 22.
In the present specification, the word "top" is a top in
the up-down direction, and "bottom" is a bottom in the up
down direction. Further, the size of the raw material
refers to the dimension of the longest portion of the raw
material.
[0032]
The washing device 11 is for washing the raw material
with water. For example, the washing device 11 includes a
washing tank 30 having an opening at an upper portion
thereof, a stirrer 31 that stirs the raw material in the
washing tank 30, a water supply part and a water discharge
part (not shown) for the washing tank 30, and the like. The
washing device 11 can wash the raw material input into the
washing tank 30 with water stored therein with the water
while stirring the raw material with the stirrer 31.
[0033]
The compression molding device 12 is for molding solid
fuel by compressing a raw material having a size larger
than that of powder in a state where water has adhered
thereto. For example, a so-called briquette machine may be
used for the compression molding device 12. For example,
the compression molding device 12 includes a casing 40
having a substantially cylindrical shape or a substantially
square tube shape whose center axis is directed in the up
down direction, an input part 41 which is provided at an
upper portion of the casing 40 and into which the raw
material is input, a pusher 42 provided at the casing 40 to
push the raw material, a compressor 43 provided at the
lower portion of the casing 40 to mold solid fuel by
compressing the pushed raw material, a heating unit 44 that
heats the molded fuel, a discharge part 45 that discharges
the fuel, and the like.
[0034]
The input part 41 is configured to be open such that
the raw material larger in size than powder can be input.
The compressor 43 is configured such that the pressure for
compressing the raw material can be adjusted, and can
compress the raw material in the range of 200 MPa or more
and 350 MPa or less, for example. Further, the compressor
43 can mold the raw material into solid fuel with a size of
mm or smaller.
[0035]
For example, the compression molding device 12 has a
transport path 46 that transports the fuel compressed by
the compressor 43 to the discharge part 45. The transport
path 46 is made to gradually rise as it approaches the
discharge part 45. The heating unit 44 is provided in the
vicinity of the discharge part 45 in the transport path 46.
The waste water generated in the compressor 43 can be
prevented from flowing to the heating unit 44 or the
discharge part 45.
[00361
The compression molding device 12 can compression-mold
the raw material with the compressor 43 while pushing the
raw material input from the input part 41 of the casing 40
with the pusher 42, heat and dry the molded raw material
with the heating unit 44, and then discharge it from the
discharge part 45. The discharge part 45 is connected to,
for example, a fuel storage facility.
[0037]
The first transport unit 13 is, for example, a belt
conveyor that transports the raw material cut by the
cutting device 10 to the washing device 11. For example,
the first transport unit 13 is provided to extend from the
discharge part 22 of the cutting device 10 to above the
washing tank 30 of the washing device 11. The first transport unit 13 can transport the raw material carried out from the discharge part 22 of the cutting device 10 to above the washing tank 30 and drop it into the washing tank
30.
[00381
The second transport unit 14 is, for example, a screw
conveyer that transports the raw material washed by the
washing device 11 to the compression molding device 12. The
second transport unit 14 is provided to extend from the
washing tank 30 of the washing device 11 to above the input
part 41 of the compression molding device 12. The second
transport unit 14 can transport the raw material washed in
the washing tank 30 of the washing device 11 to above the
input part 41 of the compression molding device 12 and drop
it into the casing 40.
[00391
Next, a method for producing fuel that is performed in
the device for producing fuel 1 configured as described
above will be described. Fig. 2 is a flow chart showing an
example of a main process of the method for producing fuel.
[0040]
First, a biomass raw material such as sorghum is cut
(process Sl). The biomass raw material is input from the
input part 21 of the cutting device 10 in an unprocessed
state and roughly cut by the single-stage cutter 23. The raw material is cut to a size of 10 mm or larger and 50 mm or smaller, and preferably 10 mm or larger and 30 mm or smaller.
[0041]
The raw material cut by the cutting device 10 is
discharged from the discharge part 22 and transported to
the washing device 11 by the first transport unit 13. The
raw material is washed with water in the washing device 11
(process S2). The raw material is input into the washing
tank 30 with water stored therein of the washing device 11,
and washed while being stirred by the stirrer 31.
[0042]
The raw material washed by the washing device 11 is
transported to the compression molding device 12 by the
second transport unit 14 in a state where water has adhered
thereto. In the compression molding device 12, the raw
material which has a size of 10 mm or larger and 50 mm or
smaller, and to which water has adhered, is compression
molded (process S3). The raw material is input into the
input part 41 of the compression molding device 12, pushed
by the pusher 42, and compressed by the compressor 43 to be
molded into solid fuel. At this time, the raw material is
compressed, for example, at pressure in the range from 200
MPa to 350 MPa, and more preferably in the range of 230 MPa
to 300 MPa, to be molded into solid fuel with a size of 50 mm or smaller. The shape of the fuel is not particularly limited and may be, for example, a cylindrical shape, a cuboid shape, a spherical shape, or the like.
[0043]
As a result, the fuel has bulk specific gravity of
0.35 or more and 0.65 or less. The moisture content of the
fuel is 10% or more and 50% or less with respect to the raw
material before the cutting process Sl. Further, the
chlorine component of the fuel is 30% or less with respect
to the raw material before the cutting process Sl, the
potassium component of the fuel is 50% or less with respect
to the raw material before the cutting process Sl, and the
sodium component of the fuel is 80% or less with respect to
the raw material before the cutting process S1.
[0044]
Thereafter, the fuel is heated by the heating unit 44,
discharged from the discharge part 45, and transported to
the fuel storage facility.
[0045]
According to the present embodiment, since the
production of fuel includes the cutting process S1 of
cutting the biomass raw material, the washing process S2 of
washing the cut raw material with water, and the
compression molding process S3 of molding fuel by
compressing the raw material which has a size of 10 mm or larger and 50 mm or smaller and to which washing water has adhered, there is no pulverization process or drying process as in the related art, so that the overall energy consumption in the fuel production process can be reduced and the production cost can be reduced. Further, in the compression molding process S3, the raw material with water adhered thereto and having a size of 10 mm or larger and 50 mm or smaller, which is larger than the powder in the related art, is compressed, so that the chlorine component and the alkaline component can be sufficiently removed along with the water from the raw material.
[0046]
If the raw material is pulverized to a size of less
than 10 mm, the pulverization process consumes energy.
Further, if the raw material is pulverized to a size of
less than 10 mm, the raw material does not sink properly
during washing, it may be difficult to collect the stirred
material, and dust countermeasures are required at a
cutting outlet or at the time of transportation, which is
not preferable. If the raw material is cut to a size of 50
mm or larger, a finally produced fuel piece becomes large,
so that it cannot be used as fuel in some cases.
[0047]
Since the compression molding process S3 is performed
at pressure of 200 MPa or higher and 350 MPa or lower,
appropriate fuel intensity can be obtained.
[0048]
Since the fuel is compression-molded such that the
bulk specific gravity is 0.35 or more and 0.65 or less, the
transportation amount per unit volume is increased, and the
transportation cost including import from overseas and
export to overseas can be reduced.
[0049]
Since the moisture content of the fuel is 10% or more
and 50% or less with respect to the raw material before
cutting, the fuel becomes fuel whose lower heating value
per unit weight is high, and the amount of heat during use
of the fuel can be increased. As a result, fuel consumption
in a boiler can be reduced. Further, since the density of
the fuel is increased, the transportation cost can be
reduced.
[0050]
The chlorine component of the fuel is 30% or less with
respect to the raw material before cutting, the potassium
component, which is one of the alkaline components of the
fuel, is 50% or less with respect to the raw material
before cutting, and the sodium component, which is one of
the alkaline components of the fuel, is 80% or less with respect to the raw material before cutting. As a result, the chlorine component and alkaline component of the fuel can be sufficiently reduced.
[0051]
According to the present embodiment, since the fuel
which is made of the biomass raw material having a size of
mm or larger and 50 mm or smaller and has bulk specific
gravity of 0.35 or more and 0.65 or less is produced, it is
possible to realize fuel suitable for transportation.
[0052]
<Second Embodiment>
The embodiment described above has three processes
that include the cutting process, the washing process, and
the compression molding process. However, the present
invention may include a method in which a cutting process
and a washing process are performed, a cutting process is
performed again, and then a compression molding process is
performed. Hereinafter, an example of such a case will be
described as a second embodiment. Fig. 3 is a schematic
diagram showing an example of the configuration of the
device for producing fuel 1 in the second embodiment.
Unless otherwise specified, the configuration of the device
for producing fuel 1 in the present embodiment is the same
as that in the first embodiment, and common configurations are denoted by the same reference numerals and description thereof is omitted.
[00531
The device for producing fuel 1 performs, for example,
a biomass raw material cutting process, a washing process,
a cutting process, and a compression molding process in
succession in this order to produce solid fuel.
[0054]
The device for producing fuel 1 includes, in addition
to the cutting device 10, the washing device 11, the
compression molding device 12, and the first transport unit
13, a cutting device 60 provided between the washing device
11 and the compression molding device 12, a second
transport unit 61 that transports the raw material washed
by the washing device 11 to the cutting device 60, and a
third transport unit 62 that transports the raw material
cut by the cutting device 60 to the compression molding
device 12.
[00551
The cutting device 60 has the same configuration as
the cutting device 10 described above. That is, the cutting
device 60 is for roughly cutting the water-washed raw
material to a size of 10 mm or larger and 50 mm or smaller.
For example, a crusher having a single-stage cutter may be
used for the cutting device 60. For example, the cutting device 60 includes a hopper 70 having a substantially cylindrical shape or a substantially square tube shape whose center axis is directed in the up-down direction, an input part 71 which is provided at an upper portion of the hopper 70, and into which the raw material is input, a discharge part 72 provided at a lower portion of the hopper to discharge the raw material, and a single-stage cutter
73 provided between the input part 71 and the discharge
part 72 to cut the raw material. The cutting device 60 can
cut the raw material input from the input part 71 of the
hopper 70 to a size of 10 mm or larger and 50 mm or smaller
by the single-stage cutter 73 and discharge the cut raw
material from the discharge part 72. The raw material may
be cut to a size of 10 mm or larger and 50 mm or smaller in
the cutting device 60, and in the cutting device 10, the
raw material is cut to a size larger than the above size.
[00561
The second transport unit 61 is, for example, a screw
conveyer that transports the raw material washed by the
washing device 11 to the cutting device 60. The second
transport unit 61 is provided to extend from the washing
tank 30 of the washing device 11 to above the input part 71
of the cutting device 60. The second transport unit 61 can
transport the raw material washed in the washing tank 30 of the washing device 11 to above the input part 71 of the cutting device 60 and drop it into the hopper 70.
[0057]
The third transport unit 62 is, for example, a belt
conveyor that transports the raw material cut by the
cutting device 60 to the compression molding device 12. For
example, the third transport unit 62 is provided to extend
from the discharge part 72 of the cutting device 60 to
above the input part 41 of the compression molding device
12. The third transport unit 62 can transport the raw
material carried out from the discharge part 72 of the
cutting device 60 to above the input part 41 of the
compression molding device 12 and drop it into the casing
40.
[0058]
Next, a method for producing fuel that is performed in
the device for producing fuel 1 configured as described
above will be described. Fig. 4 is a flow chart showing an
example of the main process of the method for producing
fuel.
[0059]
First, a biomass raw material such as sorghum is cut
(process Sl). The biomass raw material is input from the
input part 21 of the cutting device 10 in an unprocessed
state and roughly cut by the single-stage cutter 23. The raw material is cut to a size of 50 mm or larger and 500 mm or smaller, for example.
[00601
The raw material cut by the cutting device 10 is
discharged from the discharge part 22 and transported to
the washing device 11 by the first transport unit 13. The
raw material is washed with water in the washing device 11
(process S2). The raw material is input into the washing
tank 30 with water stored therein of the washing device 11,
and washed while being stirred by the stirrer 31.
[0061]
The raw material washed by the washing device 11 is
transported to the cutting device 60 by the second
transport unit 61 in a state where water has adhered to the
raw material. In the cutting device 60, the raw material is
cut again (process S3). The raw material is input into the
input part 71 of the cutting device 60 and roughly cut by
the single-stage cutter 73. The raw material is cut to a
size of 10 mm or larger and 50 mm or smaller, and
preferably 10 mm or larger and 30 mm or smaller.
[0062]
The raw material cut by the cutting device 60 is
transported to the compression molding device 12 by the
third transport unit 62. In the compression molding device
12, the raw material which has a size of 10 mm or larger and 50 mm or smaller, and to which water has adhered, is compression-molded (process S4). The raw material is input into the input part 41 of the compression molding device
12, pushed by the pusher 42, and compressed by the
compressor 43 to be molded into solid fuel. At this time,
the raw material is compressed, for example, at pressure in
the range from 200 MPa to 350 MPa, and more preferably in
the range of 230 MPa to 300 MPa, to be molded into solid
fuel with a size of 50 mm or smaller.
[00631
As a result, the fuel has bulk specific gravity of
0.35 or more and 0.65 or less. The moisture content of the
fuel is 10% or more and 50% or less with respect to the raw
material before the cutting process Sl. Further, the
chlorine component of the fuel is 30% or less with respect
to the raw material before the cutting process Sl, the
potassium component of the fuel is 50% or less with respect
to the raw material before the cutting process Sl, and the
sodium component of the fuel is 80% or less with respect to
the raw material before the cutting process S1.
[0064]
Thereafter, the fuel is heated by the heating unit 44,
discharged from the discharge part 45, and transported to
the fuel storage facility.
[00651
According to the present embodiment, since the
production of fuel includes the compression molding process
S4 of molding fuel by compressing the raw material which
has a size of 10 mm or larger and 50 mm or smaller and to
which washing water has adhered, there is no pulverization
process or drying process as in the related art, so that
the overall energy consumption in the fuel production
process can be reduced and the production cost can be
reduced. Further, in the compression molding process S4,
the raw material with water adhered thereto and having a
size of 10 mm or larger and 50 mm or smaller, which is
larger than the powder in the related art, is compressed,
so that the chlorine component and the alkaline component
can be sufficiently removed along with the water from the
raw material.
[00661
The device for producing fuel 1 in the first and
second embodiments described above may have other
configurations. For example, the configurations of the
cutting device 10, the washing device 11, the compression
molding device 12, the first transport unit 13, the second
transport units 14 and 61, the cutting device 60, the third
transport unit 62, and the like are not limited to those in
the embodiments described above, and other configurations
may be used.
[0067]
For example, as shown in Fig. 5, the cutting device 10
may be configured such that the hopper 20 having a
substantially cylindrical shape or a substantially square
tube shape is disposed with the center axis thereof
directed in the horizontal direction and the raw material
is input in the horizontal direction from the input part
21. Further, in this case, as shown in Fig. 6, the device
for producing fuel 1 may be configured such that the raw
material is directly input from the cutting device 10 to
the washing device 11 without the first transport unit 13.
[0068]
Further, as shown in Fig. 7, the cutting device 10 and
the washing device 11 may be integrated. In this case, the
cutter 23 of the cutting device 10 may be provided inside
the casing of the washing device 11. In this case, the raw
material input into the casing of the washing device 11 is
cut by the cutter 23 of the cutting device 10 and then
washed in the washing tank 30 of the washing device 11.
[00691
The device for producing fuel 1 described in the above
embodiments can be used as a facility of a plant. For
example, as shown in Fig. 8, a plant 100 includes the
device for producing fuel 1, and a combustion facility 101 that burns the fuel produced by the device for producing fuel 1.
[0070]
The combustion facility 101 includes a combustion
furnace 120 that is supplied with, for example, biomass
fuel as fuel derived from a biomass raw material and burns
the biomass fuel in the furnace, a cyclone 130 that
separates solid contents from a combustion gas generated by
burning the biomass fuel, a measurement unit 140 that
measures each component in the combustion gas, and a
superheater 150 that is superheated by heat exchange with
the combustion gas.
[0071]
The combustion furnace 120 is, for example, a
circulating fluidized bed boiler (CFB). The combustion
furnace 120 is provided with a fuel feeder 122 that
supplies the biomass fuel from the device for producing
fuel 1 into the furnace.
[0072]
The combustion furnace 120 is configured in a
vertically long tubular shape, and burns the biomass fuel
that is supplied from the fuel feeder 122 in the furnace.
The combustion furnace 120 is a fluidized bed furnace that
burns the biomass fuel while making it flow in a fluidized
bed. Further, the combustion furnace 120 is a circulating fluidized bed furnace to which solid contents each having a particle size equal to or larger than a predetermined particle size are returned by the cyclone 130. The temperature inside the combustion furnace 120 is not particularly limited. However, the temperature can be set such that the temperature of the combustion gas becomes a temperature in a range of about 800 to 10000C.
[0073]
When the biomass fuel supplied from the fuel feeder
122 to the combustion furnace 120 is burned, a combustion
gas is produced. Further, although not shown in the
drawings, a water pipe can be installed on the furnace wall
of the combustion furnace 120, and saturated vapor can be
produced by exposing the water pipe to the combustion gas
in the combustion furnace 120.
[0074]
The cyclone 130 is a solid-gas separation device that
separates the solid contents each having a particle size
equal to or larger than a predetermined particle size,
which are discharged from the combustion furnace 120, from
the combustion gas, and returns them to the combustion
furnace 120. The cyclone 130 can separate the solid
contents each having a particle size equal to or larger
than a predetermined particle size from the combustion gas
and return the solid contents to the inside of the combustion furnace 120, and can send the combustion gas from which the solid contents have been separated to the measurement unit 140. The sorting particle size of the solid content by the cyclone 130 is not particularly limited. However, it can be set to, for example, about 20 pm. In the measurement unit 140, the concentrations of the components in the combustion gas can be measured.
[0075]
The superheater 150 has a pipe (not shown) through
which the saturated vapor generated by the heat of the
combustion furnace 120 flows, and can superheat the
saturated vapor by heat exchange between the combustion gas
and the superheater 150. The combustion gas discharged from
the superheater 150 is sent to each facility (a downstream
side device) installed downstream of the superheater 150.
Further, the saturated vapor superheated by the superheater
150 is used, for example, to drive a power generation
turbine.
[0076]
The combustion facility 101 described above is an
example and is not limited thereto. Further, the combustion
facility 101 does not need to necessarily configure the
plant 100 that includes the device for producing fuel 1,
and may be a separate facility provided to burn the fuel
produced by the device for producing fuel 1.
[0077]
In the combustion facility 101 described above,
various parameters for burning the biomass fuel as fuel
derived from a biomass raw material may be adjusted. The
biomass fuel is made of a biomass raw material having a
size of 10 mm or larger and 50 mm or smaller, and has bulk
specific gravity of 0.35 or more and 0.65 or less. The
various parameters include at least any of a biomass fuel
supply amount (biomass fuel supply rate), a combustion
temperature, a supply amount of oxygen necessary for
combustion, an additive supply amount, and various
parameters for treatment of an exhaust gas and ash which
are generated by combustion.
[0078]
For example, as shown in Fig. 9, the combustion
facility 101 has an adjusting unit 160 that adjusts various
parameters. For example, the adjusting unit 160 includes an
instrument such as a valve for adjusting various
parameters, and software or hardware for operating the
instrument. For example, the user inputs information
necessary for adjusting various parameters to the adjusting
unit 160, and the adjusting unit 160 adjusts the various
parameters, based on the input information.
[0079]
For example, the supply amount of the biomass fuel
(the supply rate of the biomass fuel) from the fuel feeder
122 to the combustion furnace 120 is adjusted between 0 and
the amount of fuel (ton/h or m 3 /h) that satisfies the
required amount of heat, the combustion temperature in the
combustion furnace 120 is adjusted between room temperature
and the required temperature (0C), the supply amount of
oxygen necessary for combustion with respect to the
combustion furnace 120 is adjusted to the air amount
corresponding to an excess air ratio (air ratio), and the
supply amount of an additive such as ammonia (or urea) for
denitrification, limestone (or slaked lime) for
desulfurization, or sand (fluid medium), for example, is
adjusted to an appropriate amount. Further, the flow rate,
temperature, and pressure of the exhaust gas as various
parameters for treatment of the exhaust gas and ash that
are generated by combustion are adjusted to appropriate
amounts in the design range. Various parameters are not
limited to those listed above.
[00801
The treatment of the exhaust gas that is generated by
combustion is performed such that mainly NOx, SOx, and
dust, which are regulated by the Air Pollution Control Law,
are equal to or lower than the regulation values. For
example, as to NOx, a denitrification method by two-stage combustion and a chemical or a catalyst is used. Ammonia or urea is used as the chemical at this time. Further, as to
SOx, a desulfurization method by a chemical is used. As the
chemical at this time, in the in-furnace desulfurization,
limestone is used, and in the flue-blown desulfurization,
slaked lime is used. Dust is captured by a bag filter. The
exhaust gas in which soot has been treated is discharged
outside the system (atmosphere) at a flow velocity of about
m/s (at actual temperature) through a chimney. As the
ash, there are BA (bottom ash) and FA (fly ash), each of
which is stored in a storage tank and discharged outside
the system by a vehicle or a ship at a certain time. The
ash is effectively used outside the system or is subjected
to waste treatment (in a final disposal site). Various
parameters for treatment of the exhaust gas and ash
generated by combustion, which are adjusted by the
adjusting unit 160, include parameters for appropriately
performing treatment of the exhaust gas or discharge of the
ash.
Examples
[0081]
An experiment was performed to verify the rates of
increase or decrease in the chlorine component and alkaline
component of the fuel produced by the method for producing fuel and the device for producing fuel according to the present invention.
[0082]
(Example 1)
The components of the raw material before cutting,
which is sorghum, were analyzed, and the amount of chlorine
component and the amount of alkaline component were
measured. Further, the same raw material was cut to a size
of about 30 mm, washed with water, and then compression
molded into fuel in a state where water was adhered to the
raw material. At this time, the raw material was compressed
at pressure of 300 MPa to mold a columnar fuel having an
axial dimension of about 50 mm. Then, the components of the
fuel were analyzed, and the amount of chlorine component
and the amount of alkaline component were measured. The
component analysis was performed using an ion chromatograph
(manufactured by Thermo Fisher Scientific) for the chlorine
component and using an atomic absorption spectrophotometer
(manufactured by Shimadzu Corporation) for the alkaline
component.
[0083]
The rate of increase or decrease in the chlorine
component of the fuel with respect to the raw material
((the amount of chlorine component of fuel)/(the amount of
chlorine component of raw material) x 100%) and the rate of increase or decrease in the alkaline component (a sodium component and a potassium component)((the amount of alkaline component of fuel)/(the amount of alkaline component of raw material) x 100%) were calculated from the amount of the chlorine component and the amount of the alkaline component of the raw material before cutting and the amount of the chlorine component and the amount of the alkaline component of the fuel after compression molding.
The rate of increase or decrease in the chlorine component
was 14%, and the rate of increase or decrease in the sodium
component was 77%, and the rate of increase or decrease in
the potassium component was 39%.
[0084]
(Comparative Example 1)
After the raw material was washed, it was dried to a
moisture content of 40%, and then the raw material was
compression-molded into fuel. Other matters are the same as
those in Example 1. The rate of increase or decrease in the
chlorine component was 89%, and the rate of increase or
decrease in the sodium component was 140%, and the rate of
increase or decrease in the potassium component was 118%.
[0085]
(Comparative Example 2)
After the raw material was washed, it was dried to a
moisture content of 10%, and then the raw material was compression-molded into fuel. Other matters are the same as those in Example 1. The rate of increase or decrease in the chlorine component was 117%, and the rate of increase or decrease in the sodium component was 160%, and the rate of increase or decrease in the potassium component was 118%.
[00861
Fig. 10 is a graph showing the rates of increase or
decrease in chlorine, sodium, and potassium components in
Example 1, Comparative Example 1, and Comparative Example
2.
[0087]
Next, an experiment was performed to verify the
optimum pressure in the compression molding process for
obtaining the appropriate intensity of the fuel.
[00881
The compression molding process was performed by
changing the compression pressure with respect to the raw
material to 0 MPa, 150 MPa, and 300 MPa, and the intensity
of the fuel in each case was measured. With respect to the
intensity of the fuel, force was applied to a columnar fuel
after compression from an axial direction and a lateral
direction, and force at the point in time when the fuel
collapsed was measured and determined as the intensity of
the fuel. Fig. 11 shows the ratio of intensity of the fuel
at each compression pressure in a case where the optimum intensity of the fuel is set to 100%. In a case where the compression pressure was 150 MPa, the intensity of the fuel was 50% of the optimum intensity, and in a case where the compression pressure was 300 MPa, the intensity of the fuel was 140% of the optimum intensity.
Industrial Applicability
[00891
The present invention is useful in providing a method
for producing fuel and a device for producing fuel, in
which it is possible to sufficiently remove a chlorine
component and an alkaline component in a raw material while
reducing energy consumption.
