    A method of treating process gases coming from a gasification reactor before entry of such process gases into a system of waste heat utilization. The process gases are cooled off to a temperature of at least 800 DEG C. before entry thereof into the waste heat system. Thereafter, the gases are extensively freed of solid matter in a cyclone separator system located ahead of the convective cooling system, and thereafter the gases are cooled off further to a temperature of at least 250 DEG C. in a convective cooling system.

    The invention relates to a method for treating generator gases produced in gas generators before entering them in a heat recovery system.
    The purpose of the invention is to increase the efficiency of heat transfer and reduce energy consumption.
    The drawing shows a diagram of an apparatus for carrying out the method.
    The generator gas leaving the gas generator with a temperature of 1500 ° C is cooled in the pipeline 1 to or below by indirect heat exchange on the pipe cooling surfaces 2 (such as a pipe in a pipe). Between the pipe surfaces 2 and the wall of the pipeline 1, an insulating padding mass 3 is additionally provided. Pipeline 1 is provided on the outside with -. cleaning elements 4 that clean the cooling surfaces as they become soiled. The gases then enter the cyclone 5, in which a part of the solid particles in the gas is deposited.
    This cyclone is installed in tank 6. In the cyclone, mixing of the generating gas that started in pipeline 1 continues due to the presence of solid particles in the gas stream. The heat recovery boiler, in which convective heat exchange is carried out, is provided with various cooling surfaces 7 and 8, 9 and 10 arranged along the walls of the boiler, made in the form of
