<p>A system for pyrolysis and combustion of combustible solid material, such as waste, which comprises a pyrolysis chamber (24) having a series of spaced vertically disposed movable grates (37,38,40,42), forming a plurality of stages in the pyrolysis chamber (24). Movable grates (37,38,40,42) being synchronized for successive actuation whereby the charge of feed material (10) is successively passed through each of the stages to the bottom of the pyrolysis chamber (24). Air is introduced into each of such stages and into the bottom of the pyrolysis chamber (24). A feed-lock apparatus is provided including a hopper (14) for receiving particulate feed material and means (16,18) for compressing the particulate feed material into a compacted block (26) which temporarily functions as a gas seal from the pyrolysis chamber (24), and for introducing the compacted block into the upper section of the pyrolysis chamber (24). An exit conduit (64) is provided for removing overhead fuel gas from the pyrolysis chamber (24). An ejector, is provided for introducing the overhead fuel gas from the exit conduit (84) into a combustion chamber (73). A water-filled discharge conveyor (58) is provided in the bottom of the pyrolysis chamber (24), and removing the resulting slurry therefrom.</p> |
