Specific embodiment
Hereinafter, the burner of embodiment of the present invention is illustrated based on attached drawing.In addition, burning of the invention fills
Structure shown in embodiment not limited to the following is set, in the range of not changing inventive concept, can suitably change and implement.
The present inventor is conceived to the formation of the clinker during bamboo burning, and by experimental study by by bamboo with
Other biological material mixes the generation that whether can inhibit clinker.
As biological material, there are the barks of the thinnings of deodar and cypress etc..This bark is industrial waste, at present
As bark compost, it may be considered that use bark as biomass fuel.
Bark contains a large amount of calcium component, and burning bark can generate calcium oxide (CAO) in ashes.The inventors discovered that such as
Fruit calcium oxide (CAO) is present in ashes, even if not reducing ashes there are potassium oxide (K2O) in ashes by burning bamboo
Fusing point, can also prevent the generation of clinker.
Therefore, in the present invention, the material for bark being mixed with bamboo wood material and being obtained is used as biomass fuel and is burning
It burns in room 1.Illustrate embodiments of the present invention referring to Fig. 2.
In the Fig. 2 for indicating embodiment of the present invention, burner has structure identical with device shown in FIG. 1.It is right
It is omitted the description here in same section mark the same symbol in order to avoid repeated explanation.
As shown in Fig. 2, combustion chamber 1 is provided with the input port 12A for supplying biomass fuel, by bark 22 and bamboo wood material
21 mixed biomass fuels 2 are put into from input port 12A.Then, the biomass fuel 2 mixed with bamboo wood material 21 of bark 22 fires
It burns.In Fig. 2, by 22 blacking of bark in biomass fuel 2.
As described above, by mixing the bark 22 of the coniferous trees such as the deodar of appropriate amount, cypress with bamboo wood material 21, it can
To prevent the generation of clinker.As a result, clinker will not block the hole 11A of fire grate 11, it can supply and burn from the hole 11A of fire grate 11
Air, so as to maintain continuous burning.Bark 22 can be the bark of the broad leaf tree in addition to coniferous tree.
Again, it is preferred to process bamboo wood material, make it easier to burn, such as directly cuts bamboo or be made into fragment.
Table 1, which illustrates, mixes bamboo wood material and bark, when changing mixing ratio and the burning of bamboo wood material and bark, is based on
The softening points of the burning ashes that the JISM8801 characteristic melting temperature of ashes " measure " is determined, fusing point and melt flows point it is molten
Melt the result of characteristic.Recycle the ashes that burn under three kinds of states: the bamboo wood material of 30% weight and the bark of 70% weight, 50%
The bamboo wood material of weight and bark, the bamboo wood material of 80% weight and the bark of 20% weight of 50% weight.It is made and is tried using ashes
Heap is tested, the laser heating test reactor in furnace, and measure temperature when specific change occurs for test reactor shape.Here, softening point is
The apex of test reactor melts and starts the temperature being rounded, and fusing point is test reactor melting, and height becomes the apparent widths of bottom
Half when temperature, melt flows point is the one third of height when smelt flow reaches fusing point to supporting station, highly
Temperature.
Table 1
As shown in table 1, when bark and bamboo wood material mix combining combustion, mixed proportion is 80% weight of bamboo wood material and bark
The fusing point of burning ashes in the case where 20% weight is also 1250 DEG C.Since the temperature in combustion chamber 1 is about 1000 DEG C,
It can learn that burning ashes will not melt, the generation of clinker can be prevented.
Next, to mixing bark with bamboo wood material and changing mixing ratio the potassium oxide (K that generates when burning2O), aoxidize
Calcium (CaO) and silica (SIO2) the weight of metal oxide be measured, and by the knot for the weight % ratio being measured to
Fruit is shown in Fig. 3.In Fig. 3, black circles are silica (SiO2), black triangle is potassium oxide (K2O), black square is
Calcium oxide (CaO).
As shown in figure 3, even if the mixed proportion of bamboo wood material and bark changes, silica (SiO2) ratio also without too
Big variation, but when the mixed proportion of bamboo wood material increases, potassium oxide (K2O) increase, calcium oxide (CaO) is reduced.Also, it is reaching
To 85% weight bamboo wood material and 15% weight bark before, calcium oxide (CaO) in ashes is higher than potassium oxide (K2O).?
In the state that calcium oxide (CaO) is more, the fusing point of ashes is 1127 DEG C or more, will not generate clinker.
Thus, it is only necessary to the mixed proportion of bamboo wood material 21 and bark 22 in biomass fuel is set, so that in burning ashes
The weight % of calcium oxide (CaO) is greater than potassium oxide (K2O weight percent).
It is 85% weight in bamboo wood material 21 according to Fig. 3, before bark 22 is 15% weight, the calcium oxide (CaO) in ashes
More than potassium oxide (K2O), but bamboo and bark are all grown in nature, present in calcium and potassium be to change, because
This, it may be desirable to, use bark 22 and the mixed biomass of 80% weight bamboo wood material 21 below more than 20% weight
Fuel 2, so that calcium oxide (CaO) can more reliably be greater than potassium oxide (K in ashes2O)。
In addition, bark is easy to tangle, become blocky if only bark, it is difficult to be used as fuel, but work as bark 22 and bamboo
When material 21 mixes, bamboo wood material 21 can inhibit bark 22 entangled with one another, can inhibit to become blocky, also have and be easily processed biomass
The advantages of fuel 2.As described above, failing the bamboo made full use of and bark by using as industrial waste, can provide not
The biomass fuel for generating clinker, without carrying out the modification etc. of bamboo.
In the case where the bottom surface of combustion chamber 1 is arranged in fire grate 11, if using the bamboo wood material 21 and bark of aforementioned present invention
22 mixed biomass fuels 2 burn, then will not generate clinker, can make ash while keeping combustion air supply
Cinder is fallen downwards from the hole 11a of fire grate 11.
Burner shown in Fig. 2 is equipped with the fire grate 11 for carrying out air supply in the bottom surface of combustion chamber 1, supplies and fires from bottom
Air is burnt, but the form of combustion chamber is without being limited thereto, can be applied to various combustion chambers.
