The subject of the invention is an apparatus fro combusting fuel to heat a fluid. Said apparatus comprises a fluidized bed combustor (12); means (40) for conveying combustion bed solids to the gasifier; a fluidized bed gasifier (10); means for classifying particulates in the gasifier; means(62, 64) for removing the gaseous products and small particulates from the gasifier and injecting them into the combustor; injector means (64) consisting of perforated pipes located near the bottom of said fluidized bed combustion bed; said perforated pipes having outlets that are spaced relatively closely together compared to the depth of the combustion bed and said perforated pipes being placed relatively close to each other compared to the depth of the combustion bed. An application is handling multiple fuels in a bubbling-bed fluidized bed combustor, a number of elements being combined together and a number of systems utilizing these elements in order to be able to appropriately process different types of fuels |
