Method for optimizing structure of a fluidized bed boiler and fluidized bed combustion boiler manufactured according to this method

摘要

Fluid boiler with heat exchange surfaces of adjacent with a stationary oxidation fluid layer (2) in suspension, which consists of a layer of inert material with a height up to 1 mA granules of a size up to 3 mm in which fluid boiler is equipped with a combustion air to the fluidized bed to zafukanie (2) in suspension under pressure of 3000-10500 Pa to achieve fluidization velocity from 0.3 to 1.3 m / s, measured at ambient temperature and pressure, and the secondary air inlet, a heat transfer surface formed on the transfer of 10 to 50% of heat output fluidized bed boiler of (2) in suspension adjacent to such a heat transfer surface, the heat transfer surfaces are formed by at least a part of the walls of the combustion chamber (1) of the boiler and possibly an additional heat exchanger (5) of heat, at least partially immersed in the fluidized bed (2) in suspension.
