In the above-mentioned smoke washing device, the exhaust gas from the incinerator is brought into gas-liquid contact with an absorbing liquid such as water or an alkaline aqueous solution, whereby chlorine gas or S in the exhaust gas is discharged.
Although it is intended to remove 0x and the like by absorbing it in the absorbing liquid, saturated water vapor generated when gas-liquid contact is made in the smoke washing device is cooled while being discharged from the chimney and discharged from the chimney. When exposed to the outside air, it is further cooled and often produces white smoke consisting of white steam.If this white smoke contains acidic mist such as hydrochloric acid, it is thought that it may have an unfavorable effect on environmental protection. Moreover, even if the acid mist is completely removed in the smoke washing device and the white smoke is composed of only water, the white smoke may contain harmful substances. There is a demand for the exhaust gas to be emitted in a state of eliminating white smoke, since it is likely to cause doubts among the three parties or may impair the aesthetics.

The superheater exhaust gas supply path for supplying the combustion exhaust gas from the combustion type superheater is provided to the reheater provided in the middle of the reheating pipe for guiding the exhaust steam from the high pressure side turbine to the low pressure side turbine. Therefore, the combustion exhaust gas from the combustion type superheater can be supplied as a heat source to the reheater through the superheater exhaust gas supply passage to reheat the exhaust steam from the high pressure side turbine. Therefore, it is not necessary to use a separate fuel as in the conventional case in order to heat the exhaust steam from the reheater. Alternatively, even if a separate fuel is used, the amount used can be reduced. Furthermore, since the white smoke prevention device is provided with a white smoke prevention air supply passage for supplying heat of the combustion exhaust gas from the reheater, the exhaust gas from the reheater is supplied through the white smoke prevention air supply passage. The exhaust gas from the smoke washing device is heated to a temperature higher than the dew point by leading it to the white smoke prevention device and joining it with the exhaust gas from the smoke washing device or by exchanging heat with the exhaust gas from the smoke washing device. Since the temperature can be discharged from the chimney, the exhaust gas from the chimney can be diffused into the atmosphere without producing the white smoke even when cooled by the outside air. In order to achieve the purpose of preventing the white smoke,
For example, it is conceivable that a part of the steam generated from the waste heat recovery boiler is guided to a white smoke prevention device to be indirectly heated, but in this configuration, not only the piping becomes long, but also it is supplied to the steam turbine for power generation. Because the amount of steam is reduced by that much,
With this configuration, exhaust gas from the reheater can be used as compared with the case where power generation efficiency deteriorates, so the purpose of white smoke prevention can be achieved with short piping without affecting power generation efficiency. can do.

That is, by effectively utilizing the heat quantity of the combustion exhaust gas from the combustion type superheater, not only the fuel conventionally used in the reheater can be omitted or saved, but further, By effectively using the combustion exhaust gas from the reheater, the exhaust gas from the incinerator can be discharged from the chimney without white smoke without using a new energy source, which gives a beautiful appearance. It was possible to provide an incinerator for municipal solid waste that can eliminate the inconvenience such as damage.
