発電施設で処理することが望ましい。On the other hand, RDF is extremely uneconomical for incineration at refuse incineration plants because the energy required for its production is not small. It is desirable to process at a waste power generation facility using a gasification and melting furnace system that can generate power more efficiently than using it as fuel for boilers.

ブルの原因になる。For this reason, the combustion temperature of the melting furnace becomes too high, so that it is necessary to blow cooling air or steam into the melting furnace or to recirculate the exhaust gas of the gas turbine. As the temperature of the combustion exhaust gas introduced into the heat boiler decreases, the efficiency of the steam generator decreases, and in the latter case, it is necessary to install pipes for recirculating the exhaust gas from the gas turbine, which increases costs, This may cause difficulties in handling or cause problems such as pipe corrosion.
