Abstract: The invention relates to a method for reducing the emission of organic products of incomplete combustion in the off-gases of incineration systems, wherein the off-gas containing the organic products is treated at a temperature from 150.degree. C. to 500.degree. C., under oxidative conditions, with a denox catalyst or a modified denox catalyst. A method is also provided wherein a denox catalyst may be utilized for removing organic products and nitrogen oxides from off-gases.

Abstract: The total evaporator heating surface of a steam generator with circulating atmospheric or pressurized turbulent layer firing is distributed over several partial surfaces which are arranged in a turbulence-type combustion chamber (1) in a flow-bed cooler (7) or in a waste-heat steam generator (9). The partial surface through which flow takes place first, is dimensioned for the required low-load operation of the steam generator. The steam generator is so regulated that during increasing load of the steam generator the flow-bed cooler (7) receives an increasing quantity of solids, and during sinking load it receives a decreasing quantity of solids.
