ABSTRACT:
Freshly harvested agricultural materials having a moisture content no greater than 45% by weight are burned in a furnace in which the housing thereof is divided into preburning and afterburning spaces by a baffle wall. The preburning space contains a horizontally arranged first grating adjacent the baffle wall and a second grating adjacent the first and inclined upwardly therefrom and juxtaposed with an inlet in the housing for the introduction at a constant rate of the materials onto the inclined grating, the upper portion of which is fed by a first portion of primary air for the removal of moisture from the materials, while a lower portion of the inclined grating is fed with a second portion of primary air for the air-deficient burning of the dried materials and the production of combustible gases. The horizontal grating is fed with a third portion of primary air for driving the combustible gases along the baffle wall, which acts to deflect the gases in a counterflow to the flow of the materials, the gases mixing with secondary air introduced through at least one air inlet formed in the baffle wall, the mixture being burned completely in the afterburning space.
