METHOD AND APPARATUS FOR COMBINED STEAM BOILER/COMBUSTER ANDGASIFIER

摘要

A method and apparatus for providing a steam boiler/combuster (12) and gasifier (26) that uses a primary dirty fuel, such as waste materials, or hi gh- polluting fossil fuels, and a secondary low-polluting fuel, such as biomass fuels for co~-generation of electricity while reducing harmful emissions. Th e primary fuel is burned in the combuster (16) to create steam in the steam boiler (14). The steam turns a steam turbine (18) thereby powering a first generator (22). The dirty exhaust (24) from the combuster (16) is scrubbed b y a gasifier (26). The secondary fuel and oxygen are added to the dirty exhaus t in the gasifier (26) creating gas and ash. The gas powers an engine (30) tha t turns a second generator (32) and releases a cleaner exhaust.
