Abstract: A method and apparatus for providing a steam boiler/combuster and gasifier that uses a primary dirty fuel, such as waste materials, or high-polluting fossil fuels, and a secondary low-polluting fuel, such as biomass fuels for co-generation of electricity while reducing harmful emissions. The primary fuel is burned in the combuster to create steam in the steam boiler. The steam turns a steam turbine thereby powering a first generator. The dirty exhaust from the combuster is scrubbed by a gasifier. The secondary fuel and oxygen are added to the dirty exhaust in the gasifier creating gas and ash. The gas powers an engine that turns a second generator and releases a cleaner exhaust.

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 450-650° C. at a filtration velocity of 1-5 cm/sec under a pressure of from −5 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.
