摘要: A system and method for producing product gas using residual waste liquor is described with a gasifier reactor having a fluidized bed located therein. The gasifier reactor is heated to a predetermined temperature range with either an external heater or a second fluidized bed located at a position below the first fluidized bed. A heat exchanger may be positioned in the first fluidized bed and/or the second fluidized bed for indirectly heating the respective fluidized beds. Condensing heat exchanger means recovers heat from the product gas and condenses an acid gas therefrom for recycling the chemicals. A reagent is sprayed in the condensing heat exchanger means to clean the product gas. Pressurization allows the cleaned product gas to be directly fired in a turbine.
