A system for the combustion of moist ligneous and other wastes, such as sawdust and compacted household rubbish in order to generate heat. The system includes a crusher-extractor to divide the waste matter entrained in an air stream to produce a fuel mixture that is fed into one input of an exchanger-separator whose output supplies a pyrolytic burner coupled to a boiler. The hot fumes from the boiler are fed back into the other input of the exchanger-separator which serves to mix fresh divided waste with residue or unburned waste extracted from the fumes, and to separate the waste material to be consumed in the burner from the hot gas and moisture.

A system provided with a pyrolytic burner cooperating with a boiler for effecting the combustion of a mixture of divided waste such as ligneous waste entrained in a stream of air to produce heat, said burner comprising: A. an enclosure defining a pyrolysis chamber having inlet and outlet openings, the mixture being blown into the inlet opening and being advanced in said chamber in a flow path from the inlet to the outlet opening; B. a metal thermally-conductive core having an elongated form disposed in said enclosure and extending substantially from the inlet to the outlet opening thereof to transfer some of the heat of combustion from the outlet opening to the inlet opening; and C. means to retard the advance of said mixture in said chamber, said means being constituted by a metallic element having pores therein to define a grid or screen-like structure which divides the chamber into an upstream section and a downstream section with respect to said flow path, the transfer of heat by the core being in a direction opposed to the flow path direction whereby pyrolysis of the mixture takes place in the vicinity of the inlet opening and combustion is substantially complete at the outlet opening.
