A METHOD OF OPERATING AN INCINERATOR COMPRISING A DEVICE FOR CAPTURING ASH ENTRAINED BY FLUE GAS

摘要

A method of operating an incinerator (100) for solid fuel, said incinerator (100) comprising a device (160) for separating ash from flue gas, which method comprises the step of collecting ash deposits originating from the flue gas comprising ash from the incinerator (100) resulting in collected ash; To improve the flowability of the ash collected, the method comprises the step of introducing a powdery additive material comprising i) clay and ii) calcium carbonate into the flue gas comprising ash wherein the flue gas comprising ash has at the location where the additive material is introduced a temperature of at least 700˚C, wherein the additive is introduced with a rate R of at least 0.1 times the mass of ash in the stream of flue gas comprising ash.
