ABSTRACT:
A method of and an apparatus for operating a circulating fluidized bed reactor having a furnace with a discharge port for exhaust gas, and a particle separator having an inlet connected to the exhaust gas discharge port and an outlet duct for the exhaust gas and a return duct for separated solids. The method includes the steps of arranging a bypass duct bypassing the particle separator, and conducting a partial flow of exhaust gas along the duct for increasing the fly ash content in the exhaust gas after the separator. The bypass duct is advantageously provided with means for controlling the flow of exhaust gas in the bypass duct.
