摘要

A process for burning sewage sludge in a burner, comprises using a circulating vortex layer for burning solid fuel, e.g. raw brown coal, at atmospheric pressure and between 750 and 950 deg C. A process for burning sewage sludge in a burner, comprises using a circulating vortex layer for burning solid fuel, e.g. raw brown coal, at atmospheric pressure and between 750 and 950 deg C. The smoke gas and circulating bed material are separated, and returned to the combustion chamber. The fuel and the sludge are supplied to the return line. The sludge is fed into a coal stream section which is between 100 and 250 deg C.
