BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable supply system for simultaneously supplying heat and electric power for commercial use, industrial use and the like.

[0002]

[Prior Art and Problems] In recent years, the utilization of coal has been reconsidered as an alternative energy to oil. In developing countries, which are the major producers of coal, while coal occupies the mainstream of energy, high-quality coal is consumed in specific industries such as exports, other electric power, and steelmaking, and low-calorie coal is used as a private demand. Occupies most. In developing countries, in addition to these energy situations, the power supply situation is bad, the power supply cannot keep up with the rapidly increasing power demand, power outages in large cities are not uncommon, and there are many non-electrified cities even in rural areas. Even if self-generated power is used to cope with such power circumstances, there are only generators that use expensive oil, and small-scale fueled by low-calorie coal, which accounts for the majority of private demand. Power generation system is undeveloped.

In developing countries, due to the above-mentioned energy situation and electric power situation, it is expected to develop a portable supply system which simultaneously supplies heat and electric power with low-calorie coal as fuel.

On the other hand, even in developed countries, at present, the shift of energy use from oil dependence to coal is being pursued, and the development of the above-mentioned portable supply system is awaited.

In order to meet the above-mentioned demand and provide the above-mentioned small-sized portable system, it is necessary to improve the arrangement position configuration of the conventional solid fuel combustion device and the steam boiler. That is,
Since the conventional fuel device and the boiler are connected in a plane (series), it cannot be installed without a large installation area. Also, in this conventional system,
When the high temperature combustion gas generated in the solid fuel combustion device is introduced into the steam boiler through the flue, the heat is unnecessarily dissipated on the introduction path, so that the thermal efficiency of the steam boiler is reduced.

The present invention has been made by paying attention to the above-mentioned demands and problems.
Operation control related configurations are divided into groups and each container is equipped with equipment to make it portable. None Stacked those containers in a fixed layout and arranged three-dimensionally so that they can be installed in a small installation area. It is also an object of the present invention to provide a simultaneous heat and power supply system capable of introducing high temperature combustion gas generated in a solid fuel combustion device into a steam boiler with wasteful heat dissipation.

The solid fuel combustion apparatus 1 is a low-calorie coal, its coals, wood chips, wood powder, or wood solid products (pellets) made by compressing bark, and mixed compression of coal and wood powder. It is a device that uses various solid objects such as pieces (bio-call), waste solid pieces (pellets, tablets, etc.) made by mixing and compressing waste plastics and bark or paper waste as fuel. The combustion chamber 1 has a structure in which a chain stoker 1-2 is provided in a furnace barrel 1-1, and a blower 1-3 is connected to the furnace barrel 1-1, and a solid fuel charging port 1-4 is provided. The solid fuel, which is provided at one end and is supplied from the input port, is supplied to the chain stoker 1-2 and burned by the combustion air sent from the blower 1-3, and the input port 1-4 is also provided.
The other end on the opposite side is communicated with the steam boiler 2-1 of the group 2 so that the high-temperature fuel gas is directly introduced into the steam boiler 2-1. Therefore, the upper plate of the container C ₁ and the lower plate of the container C ₂ are provided with a communication port 9 at a portion corresponding to the other end of the furnace body 1-1, and the high temperature combustion gas generated in the combustion device 1 is directly vaporized. It is configured to be introduced into the boiler 2-1. At the input port 1-4 of the combustion device 1, a solid fuel injection facility composed of a fuel storage 1-5, an input conveyor 1-6, etc. is installed in the container C.
_You will be contacted by opening the door 6 of ₁ . In addition, the blower 1-3
Is a blower that blows the primary combustion air a ₁ toward the chain stoker 1-2, and a blower that blows the secondary combustion air a ₂ from the wall of the furnace barrel 1-1 toward the flame in the furnace barrel. Yes, the combustion air of both of these causes complete combustion.

The above-mentioned boiler 2-1 of the first group 2 has a large number of smoke tubes 2-3 formed in the lengthwise direction thereof, and a smoke passage 2-4 communicating with the solid fuel combustion device 1 through a communication port 9. And the flue is connected to the smoke pipe 2-3. The communication means between the flue 2-4 of the boiler 2-1 and the communication port 9 is the flue 2
A plurality of combustion gas inlets 2-5 are opened in the lower part of -4 and are arranged in the length direction of the steam boiler 2-1. The steam boiler 2-1 communicates with a small boiler 10 composed of a large number of water pipes standing upright so as to surround the communication port 9 from three sides,
The hot water produced by this boiler is designed to flow in. The steam boiler 2-1 connects the exhaust side of an appropriate smoke pipe 2-3 to the exhaust heat exchanger 2-2, and the exhaust heat exchanger is equipped with the heat exchanger 11 of the heating circuit, so that the exhaust heat The heat is exchanged by the method, and the hot water obtained is supplied to baths, kitchens, sinks, heating, and other places that require hot water. The steam boiler 2-1
Along with the small boiler 10, it is connected to the steam hetter 3-1 of the second group 3 and the generated steam is distributed and supplied as the turbine generator 4-1 of the third group, steam for heating factories and houses, and the like. The steam boiler 2-1 is high on the communication port 9 side,
The exhaust heat exchanger 2-2 side is arranged so as to be inclined low, and the scattered dust is collected in the dust (soot) receiver 2-6 provided at the bottom of the low side. The reason why the steam boiler 2-1 is installed obliquely in this way is that in the conventional boiler, dust is accumulated in the boiler to deteriorate the thermal conductivity and reduce the thermal efficiency. Therefore, the boiler is frequently cleaned. I had to. However, if the steam boiler 2-1 is installed obliquely as described above, the dust will be collected in the dust receiver 2-6, so that the thermal conductivity will not deteriorate, and thus the thermal efficiency will not decrease, and the boiler will be cleaned every other day ( For example, every 5 to 7 days), it is possible to contribute to labor saving, shortening of operating time, etc. The soot and smoke that has passed through the exhaust heat exchanger 2-2 in the first group 2 passes through the well-known dust collecting device 2-8 and the chimney 2
-It is introduced to -7 and smoke is exhausted. The chimney 2-7 is dust.
In order to prevent the dust from being mixed in with the flue gas, a dust collection cylinder 2-9 that moves vertically is provided at the lower part inside. As shown in FIGS. 11A and 11B, the dust collecting cylinder has a dust collecting device 2 on the peripheral wall.
-Smoke exhaust inlet 2-10 is opened at the location corresponding to -8, and dust collection tube 2
-9 is connected to the dust collector 2-8, and the upper part of the dust collector 2-9 is closed to provide a smoke exhaust pipe 2-11. The lower part is formed into a tapered shape to open and close the on-off valve 2-12. It is constructed by mounting the lower end of the on-off valve on the jack 2-13. Dust collector 2
-9 is a jack operation to raise it so that the smoke exhaust inlet 2-10 communicates with the dust collector 2-8, and at the same time, the smoke exhaust passage 2-14 directly connected from the chimney 2-7 to the steam boiler 2-1. Smoke outlet 2-15
If the dust collector 2-9 is closed, the soot and smoke that has passed through the exhaust heat exchanger 2-2 is introduced into the dust collector 2-9, and the smoke is discharged from the smoke exhaust pipe 2-11.
From the lower end of the pipe, it flows into the pipe, flows out into the chimney 2-7, and is discharged. On the other hand, dust (soot) introduced in the dust collector 2-9
Is separated from the smoke and collects in the lower part of the dust collecting cylinder, and is less likely to be mixed in the flue gas. For dust collected in the lower part of the dust collecting cylinder 2-9, lower the jack 2-13, open the on-off valve 2-12 and pull out and clean. The reason for providing the smoke exhaust passage 2-14 that directly connects the chimney 2-7 and the steam boiler 2-1 is to prepare for the case where the dust collector 2-8 fails to operate due to a power failure or a failure.
If this happens, use the jack to operate the dust collector 2-9.
And the smoke exhaust introduction port 2-10 are lowered, the communication port to the dust collector 2-8 is closed by the cylinder wall, and at the same time, the smoke exhaust port 2-15 of the smoke exhaust passage 2-14 is opened and steam is discharged. Temporarily directly discharge the soot and smoke from the boiler 2-1. As the dust collector 2-8, a well-known product (for example, a dust collector called Super Klon SK type manufactured by Imai Co., Ltd., located in Ota-ku, Tokyo) is used.

The steam heter 3-1 of the second group 3 is for distributing the steam generated in the steam boiler 2-1 and the small-sized boiler 10 to the turbine generator 4-1 and the steam for heating such as houses and factories. It is a well-known machine, and those pipes are piped to the places where they are needed. The operation control device 3-2 includes a solid fuel combustion device 1, a fuel injection facility 1-6, a steam boiler 2-1, a dust collector 2-8, a power receiving and transforming facility 4-2 described below, and a standby power generation device 4-.
3. This is a well-known device that operates while controlling centrally the hot well tank 3-5, etc., and prepares a desk 3-3, a chair 3-4, etc. for the staff to monitor. Although this control device exemplifies a well-known system in which a staff member operates while monitoring the status of various devices, a fully automatic system may be introduced by introducing a computer. In addition to these facilities, the second group 3 also has a well-known hot well tank (return water tank) 3-
5, water and hot water supply pump 3-6, source water tongue 3-7, chemical injection unit 3-8, etc. are installed.

The turbine generator 4-1 of the third group 4 is
Electric power is generated by a steam turbine (not shown) that rotates with the steam generated in the steam boiler 2-1 and the electric power is transmitted to the power consumption facility via the power receiving and transforming facility 4-2. It is already well known (for example, see Shinko Co., Ltd. located in Minami-ku, Hiroshima, catalog “Energy saving by steam turbine power generation”). In addition to the above-mentioned equipment, the third group 4 is equipped with a backup power generation device 4-3, a fuel tank 4-4 for this backup power generation device, and the like.
