Abstract

A process and an arrangement are disclosed for operating a composite power station with a circulating fluidized bed furnace for solid fuels, in particular brown coal. The object of the invention is to recover and use combustion gas with high caloric values, i.e. to ensure an optimum post-combustion of the flue gas in order to achieve a maximum entrance temperature in the gas turbine. For that purpose, the flue gas partial current (15) is diverted in the substoichiometrically operated area of the fluidized bed furnace, upstream of the secondary air inlet (5), or the boiler is substoichiometrically operated as a carburetor and fresh air is added to the flue gas after the flue gas is cleaned and before it is subsequently burned. To implement this process, the combustion gas channel (15) is embedded in the substoichiometrically operated area of the fluidized bed furnace, upstream of the secondary air inlet (5), or the air channel is subdivised upstream of the boiler into controllable partial channels. One partial channel is embedded in the fluidized bed furnace and the other partial channel is embedded in the flue gas channel or in the post-combustion device.
