    摘要: There is provided a circulating fluidized bed steam generator (CFB) having an improved structural support system and an improved combined hot solids-gas separator for separating gas and solids from a combined gas-solids stream. The combined hot solids-gas separator is in the form of a cyclone assembly having a plurality of wall portions forming a separation chamber and an inlet for passage of a combined gas-solids stream into the separation chamber. The lowermost extent of the inlet forms a threshold over which the combined gas-solids stream flows in entering the separation chamber. The separation chamber is operable to separate the combined gas-solids stream into a predominantly gas exit stream and a predominantly solids exit stream in a manner by which separated out solids to be discharged from the separation chamber via the predominantly solids exit stream are collected within the separation chamber at a location lower than the inlet. The cyclone assembly further includes a separated solids discharge for the discharge therethrough of the predominantly solids exit stream having the collected separated out solids therein and a gas outlet duct for outward flow of the predominantly gas exit stream out of the separation chamber.

    摘要: Method and apparatus for controlling the distribution of secondary air (30) between at least two fuel burners (14,16) in a multiple fuel combustor (16). Total chemical energies of the individual fuel streams (44,60) are determined and compared (64,66) with the total combustor chemical energy input (62) for controlling biasing means (32,34). The determination of at least one individual fuel total chemical energy content (60) may optionally include a prompt neutron activation type analyzer (48) for on-line measurement of specific fuel chemical energy (59).
