Description

  The present invention relates to a device for storing and supplying energy by waste incineration.

  There is a waste incineration facility that generates waste heat by collecting combustion heat obtained by incinerating waste, generating steam, generating power by a turbine, and supplying power. In recent years, waste power generation is expected to play a role as a regional decentralized energy supply facility, and for that purpose, stable energy supply is indispensable. However, since the waste composition is mixed and large in fluctuation, the amount of generated steam also fluctuates greatly, and there is a problem that stable power supply is difficult. In addition, there is a demand for the development of an effective technology for storing energy generated by waste power generation.

  As a countermeasure against fluctuations in power generation, a technology has been disclosed in which an auxiliary power generation device (photovoltaic power generation panel) and a storage battery are provided side-by-side to suppress and compensate for fluctuations in power generation in waste power generation (Patent Document 1).

  Further, as a technology for storing energy obtained by waste power generation, a technology is disclosed in which waste heat from a waste incineration facility is used to generate power by a thermoelectric power generation element, and water is electrolyzed to produce, store, and use hydrogen. (Patent Document 2).

  According to the present invention, in any of the first to twelfth inventions, steam is generated by a boiler using heat of exhaust gas from an incinerator, and the steam is used to drive a steam turbine to generate power by a generator. The water is electrolyzed by the water electrolysis device to obtain hydrogen, and the hydrogen and nitrogen are used to produce ammonia in the ammonia production device. The combustion heat energy obtained by incinerating waste in an incinerator Is used to obtain ammonia as an energy source.

  According to the present invention, in a waste incineration facility provided with an incinerator, energy can be stored in the form of ammonia or supplied to a demand destination. Ammonia is easy to store for a long time at normal temperature and normal pressure, and because ammonia can be produced on a large scale, it is easier to store a large amount of energy than power storage by a storage battery. Further, ammonia has a high value as energy, such as being usable for many uses and having a high ability to follow a change in load, and can realize effective energy supply and storage. Further, the waste incineration facility can be used as a regional decentralized energy supply facility for producing and storing energy.

  In the fifth invention, since the heat from the heat exchanger that obtains heat by recovering heat from the exhaust gas from the boiler is used as a heat source in the water electrolysis device and the ammonia production device, the conventional applications have been limited. The retained heat of the exhaust gas, which is relatively low-temperature waste heat, can be effectively used, and the overall energy conversion efficiency is increased.

  In the sixth invention, since the cooling wastewater is supplied to the water electrolysis device from the cooling tower that cools the exhaust gas from the boiler with the cooling water and discharges the cooling wastewater, the raw water is supplied from the outside. There is no need, and the treatment of cooling wastewater can be simplified.

  In the seventh invention, oxygen obtained together with hydrogen in the water electrolyzer is supplied to the incinerator as an oxidizing gas for combustion, so that the generated gas (oxygen) is effectively used and the combustion efficiency of the incinerator is increased. And the combustion in the incinerator is stabilized, and the generation of harmful substances such as CO and NOx can be suppressed.

  In the eighth invention, a part of the ammonia produced by the ammonia producing device is burned by the ammonia burning device, and the superheated steam supplied from the boiler to the steam turbine is further heated by the retained heat of the generated ammonia combustion exhaust gas. Since the pressure is increased, the power generation efficiency of the steam turbine is improved.

  In the ninth invention, oxygen generated together with hydrogen in the water electrolysis device is supplied as an oxidizing gas to the ammonia combustion device according to the eighth invention, so that the generated gas (oxygen) is effectively used and the ammonia combustion device is used. The combustion efficiency of the device 16 increases.

  In the tenth invention, since part of the ammonia produced by the ammonia producing apparatus is supplied to the incinerator as an auxiliary fuel, there is no need to procure kerosene, city gas, etc. as an auxiliary fuel from the outside, and the operation is performed. Costs can be reduced.

  In the eleventh invention, the ammonia combustion exhaust gas from the ammonia combustion exhaust gas is discharged from the heat exchanger after being used to further superheat the superheated steam from the boiler in the heat exchanger. Is supplied to at least one of the incinerator, the boiler, the inlet of the denitration device or the flue on the upstream side of the denitration device, so that the ammonia combustion exhaust gas stirs and mixes in the combustion chamber and the secondary combustion section. The so-called circulating exhaust gas (EGR) effect promotes and stabilizes combustion and secondary combustion in the combustion chamber, reduces the generation of CO and thermal NOx, and reduces the residual ammonia in the ammonia combustion exhaust gas to reduce NOx. Denitration reduces NOx emissions, suppresses boiler corrosion, and effectively utilizes the heat possessed by the ammonia combustion exhaust gas. Also, by supplying ammonia combustion exhaust gas to the inlet of the denitration device or the flue on the upstream side of the denitration device, the incinerator exhaust gas is reheated using the retained heat of the ammonia combustion exhaust gas and incinerated for denitration. The reheating device required for reheating the furnace exhaust gas is not required, or the reheating can be reduced. Further, since the residual ammonia in the ammonia combustion exhaust gas reduces NOx as a denitrifying agent, it is not necessary to supply ammonia as a denitrifying agent from outside for reducing NOx, or the amount of ammonia supplied from outside is reduced. Can be reduced.

  In the twelfth invention, ammonia is produced in the combustion chamber because a part of the ammonia produced by the ammonia producing apparatus is supplied to the incinerator, the inlet of the denitration apparatus or the flue upstream of the denitration apparatus. NOx is reduced and denitrified to reduce NOx emissions. Further, since ammonia reduces NOx as a denitrifying agent in a denitrification device, it is not necessary to supply ammonia as a denitrifying agent from outside for NOx reduction. Or the supply amount of ammonia from the outside can be reduced.

<Tenth embodiment>
The tenth embodiment shown in FIG. 11 is different from the eighth embodiment in FIG. 9 in that the ammonia combustion exhaust gas from the ammonia combustion device 16 further heats the superheated steam from the boiler 2 in the heat exchanger 11. After being used, it is discharged from the heat exchanger 11, and the ammonia combustion exhaust gas is supplied to the incinerator 1, the boiler 2, the inlet of the denitration device 6 or the flue upstream of the denitration device 6. Has been added.

  The ammonia combustion exhaust gas used to raise the temperature of the superheated steam in the heat exchanger 11 is partially supplied to the incinerator 1 with respect to the next positions A1 to A3 and the superheater 2B in FIG. At position B and at position C relative to economizer 2C. The position A1 is a furnace side wall and a ceiling of the combustion chamber 21, below the grate 26 a to 26 c, a furnace downstream end wall, and ammonia combustion exhaust gas is supplied to the combustion chamber 21 from at least one of these positions. . The ammonia combustion exhaust gas is supplied from the furnace side wall toward the center of the combustion chamber 21, downward from the ceiling, upward from the grate, and upstream from the furnace downstream end wall. The position A2 is located in the gas mixing section 23, and the ammonia combustion exhaust gas is mixed with the unburned gas so as to promote the mixing of the flow P of the unburned gas and the flow Q of the combustion gas flowing from the combustion chamber 21. The gas is supplied so as to promote stirring and mixing with the secondary combustion air received in the gas mixing section 23. Further, the position A3 is located in the secondary combustion chamber 29, and is supplied so as to promote the stirring and mixing of the unburned gas flowing from the gas mixing section 23 and the secondary combustion air. It is preferable that the position where the ammonia combustion exhaust gas is supplied to the secondary combustion chamber 29 be a position where the incinerator exhaust gas from the combustion chamber 21 can be retained in the temperature atmosphere of 850 ° C. or more for 2 seconds or more. As a result, the dioxins are decomposed to prevent the emission of dioxins.

  Ammonia combustion exhaust gas is supplied to the contact heat transfer chamber 2A-3 of the boiler 2, that is, the superheater 2B, at a position B which is an inlet of the superheater 2B (the lower part of the contact heat transfer chamber 2A-3 in FIG. 13). I have.

  Further, as shown in FIG. 13, the ammonia combustion exhaust gas is supplied to a position C which is an inlet of the economizer 2C (an upper part of the economizer 2C in FIG. 13).

  Further, as shown in FIG. 11, the ammonia combustion exhaust gas is also supplied to the inlet of the denitration device 6 or the flue upstream of the denitration device 6.

  In the tenth embodiment configured as described above, when the waste is put into the incinerator 1 from the waste inlet 22, the grate (the dry grate 26a, the combustion grate 26b, and the post-combustion grate 26c). Above, the combustion air is received and burned from below the grate 26a, 26b, 26c, and combustible unburned gas and primary combustion exhaust gas are generated by the combustion of waste. The residue is discharged from the incineration ash outlet 24 as incineration ash.

  The combustion chamber 21 receives the supply of the ammonia combustion exhaust gas from the position A1, that is, from below the furnace side wall, the ceiling and the grate 26a to 26c of the combustion chamber 21, and the ammonia combustion exhaust gas supplied to the combustion chamber 21 is supplied. Prevents the flame temperature from becoming excessively high in the combustion chamber 21 and sufficiently stirs and mixes the combustible unburned gas and the combustion air in the combustion chamber 21, so that combustion is promoted and stabilized. Thus, the generation of CO is reduced, and the generation of thermal NOx is reduced by suppressing the generation of a local high-temperature field. Furthermore, residual ammonia in the ammonia combustion exhaust gas reduces NOx generated in the combustion chamber to denitrate, thereby reducing NOx emissions.

  The unburned gas flows around the front end portion 25a of the intermediate ceiling 25 and flows into the gap 27 between the ceiling and the intermediate ceiling as a flow P, while the combustion gas flows around the rear end portion 25b of the intermediate ceiling and contacts the furnace side wall. It flows as a flow Q into the gap 28 with the intermediate ceiling. The flow P and the flow Q face each other in the gaps 27 and 28, and collide and are mixed in the gas mixing unit 23. Ammonia combustion exhaust gas is supplied to the gas mixing section 23 at a position A2, and the ammonia combustion exhaust gas supplied to the gas mixing section 23 is mixed with the unburned gas from the combustion chamber 21 and the secondary gas received by the gas mixing section 23. Since the secondary combustion is promoted and stabilized by promoting the stirring and mixing with the combustion air, the generation of CO is reduced, and the generation of thermal NOx is reduced by suppressing the generation of a local high-temperature field. Furthermore, the residual ammonia in the ammonia combustion exhaust gas reduces NOx and denitrates, thereby reducing NOx emissions.

  The unburned gas and the secondary combustion air mixed in the gas mixing section 23 are subjected to secondary combustion in the secondary combustion chamber 29. At this time, in the secondary combustion chamber 29, the supply of the ammonia combustion exhaust gas is received from the position A3, and as a result of the supply of the ammonia combustion exhaust gas from the position A3, the stirring and mixing of the unburned gas and the secondary combustion air are promoted. Thus, since the secondary combustion of the unburned gas is promoted and stabilized, generation of CO is reduced, and generation of thermal NOx is reduced by suppressing generation of a local high-temperature field. Further, the incinerator exhaust gas from the combustion chamber 21 can be retained in the secondary combustion chamber at a temperature of 850 ° C. or more for a time of 2 seconds or more, and dioxins are decomposed to prevent emission of dioxins. Furthermore, the remaining ammonia in the ammonia combustion exhaust gas reduces NOx and denitrates, thereby reducing NOx emissions.

  The incinerator exhaust gas after the secondary combustion in the secondary combustion chamber 29 is led to the boiler 2, and generates steam in the evaporator 2A of the first radiation chamber 2A-1 and the second radiation chamber 2A-2, and thereafter, The above-mentioned steam is converted into superheated steam in the superheater 2B of the first radiation chamber 2A-3 of the contact heat transfer chamber.

  Ammonia combustion exhaust gas is supplied to the inlet position B of the superheater 2B, and the incinerator exhaust gas is diluted with the ammonia combustion exhaust gas. Therefore, the temperature of the incinerator exhaust gas is a temperature at which corrosion of the boiler heat transfer tube occurs. This can be suppressed, and the concentration of the corrosive gas (HCl) can be reduced, thereby suppressing the corrosion of the boiler.

  After the temperature is raised in the superheater 2B so that the steam becomes superheated steam, the incinerator exhaust gas is guided to the economizer 2C. Since the ammonia combustion exhaust gas is also supplied to the economizer 2C at the inlet position C, the condensate from the condenser (not shown) is heated by the economizer 2C by the retained heat of the incinerator exhaust gas and heated. In this case, since the retained heat of the ammonia combustion exhaust gas is also used for heating the heated water, the temperature of the heated water is increased accordingly, and the retained heat energy of the superheated steam from the boiler is increased.

  The incinerator exhaust gas used to make the condensed water into heated water in the economizer 2C is guided to a denitration device 6, as shown in FIG. 11, where NOx in the incinerator exhaust gas is decomposed and denitrated. The incinerator exhaust gas is regarded as detoxified exhaust gas. Ammonia combustion exhaust gas is supplied to an inlet position of the denitration device 6 or an upstream flue of the denitration device 6, and reheats the incinerator exhaust gas by using the heat retained in the ammonia combustion exhaust gas. Therefore, a reheating device required for reheating the incinerator exhaust gas for denitration is not required, or reheating can be reduced. Further, since the residual ammonia in the ammonia combustion exhaust gas reduces NOx as a denitrifying agent, it is not necessary to supply ammonia as a denitrifying agent from outside for reducing NOx, or the amount of ammonia supplied from outside is reduced. Can be reduced.

<Eleventh embodiment>
The eleventh embodiment shown in FIG. 12 is different from the first embodiment in FIG. 2 in that a part of the ammonia produced by the ammonia production device 2 is supplied to the incinerator 1, the inlet of the denitration device 6 or upstream of the denitration device 6. The point that is supplied to the side stack is added.

  Ammonia supplied to the incinerator 1 reduces NOx generated in the combustion chamber to denitrate and reduce NOx emissions. Since the ammonia is supplied to the inlet position of the denitration device 6 or the flue upstream of the denitration device 6 and reduces NOx as a denitration agent, it is not necessary to supply ammonia as a denitration agent from the outside to reduce NOx. Or the supply amount of ammonia from the outside can be reduced.
