    Abstract: An apparatus allowing the use of low-grade solid fuel powders (coal, lignite, peat) and products derived therefrom during cold starting periods and for backing up combustion chamber operation at low load. The pilot burner (1) has an auxiliary and pilot igniter which burns gas produced by gasifying low-grade fuel in a gasification unit (6) and a main igniter which burns the low-grade fuel powder in a storage silo (5). The combustion air is heated in an air heater (10) by the gas produced by gasifying low-grade fuel in gasification unit (6). In particular, turbulence is set up in the combustion air sent to the outlet of the pilot igniter. Application to combustion apparatus including steam generators of thermal power stations.

    Abstract: A burner for the direct heating of a fluid by the combustion of an assisted spray liquid and a gaseous substance. Above a grating are arranged spray nozzles for the spraying liquid and injectors for the gas. The said spray nozzles and injectors have independent and respective feed systems. They are arranged in space so as to enable the flowing of the fluid to be heated up, in such a way that the combustion produces a distributed giving off of heat insuring the homogenous heating up thereof in combination with convection means contributing to the stirring thereof. The burner is applicable, to steam generators, to the heating of premises and to the depollution of polluted smoke.

    Abstract: A grating for an incinerator of combustible waste comprising a plurality of parallel juxtaposed bars disposed transversely in the incinerator and extending lengthwise thereof to provide a support surface on which waste is advanced in the course of its combustion. The bars are arranged in two sets alternating with one another, the bars of one set being fixed and the bars of the second set being reciprocally movable. The bars of the one set are secured at gradually lowered positions in the incinerator to provide a downward inclination of about 15.degree. with the horizontal in the lengthwise direction of advancement of the waste. The bars of both sets are inclined with the horizontal at an angle of about 30.degree. in a direction opposite the downward inclination in the lengthwise direction. The bars of the second set are reciprocally movable in a direction parallel to their inclination and neighboring movable bars are connected by a linkage for movement in opposite direction, whereas neighboring coupled pairs of movable bars are driven conjointly.
