Abstract: In an improved system for recovering heat from a combustion gas produced by burning wastes, the combustion gas or combustible gas produced by partial burning of the wastes subjected to dust filtration in a temperature range of 450-650null C. at a filtration velocity of 1-5 cm/sec under a pressure of from null5 kPa (gage) to 5 MPa before heat recovery is effected. The dust filtration is preferably performed using a filter medium which may or may not support a denitration catalyst. Heat recovery is preferably effected using a steam superheater. The dust-free gas may partly or wholly be reburnt with or without an auxiliary fuel to a sufficiently high temperature to permit heat recovery. The combustion furnace may be a gasifying furnace which, in turn, may be combined with a melting furnace. If desired, the reburning to a higher temperature may be performed under pressure and the obtained hot combustion gas is supplied to a gas turbine to generate electricity, followed by introduction of the exhaust gas from the gas turbine into a steam superheater for further heat recovery. The system can raise the temperature of superheated steam to a sufficient level to enhance the efficiency of power generation without possibility of corrosion of heat transfer pipes by the combustion gas or combustible gas.

Abstract: The system for producing combustion ash of cellulose-containing wastes, provided with a kneading device 3 for kneading cellulose-containing wastes with a prescribed amount of liquid fuel oil, a molding device 5 for molding said kneaded mixture, and a combustion furnace 7 for burning said moldings, is characterized in that the humidity conditioning furnace 6 for adjusting the water content of said moldings is arranged between said molding device and said combustion furnace. Since the water content of said moldings is adjusted by the humidity conditioning furnace at the time of burning said moldings, the organic substances (cellulose or the like) are burned almost perfectly. Consequently, the present invention has the advantage of being able to produce combustion ash of good quality without generating such combustion residue as graphite and black smoke.
