Patent ID: 7028624

Claim:
Method of continuous treatment of domestic waste, which comprises: a) providing a reaction space; b) feeding the waste to be treated to said reaction space at a controlled rate; c) concurrently compacting said waste to form a stopper preventing leakage of gases from said reaction space; d) feeding an oxygen-containing gas to said reaction space, whereby to affect the combustion of said waste and produce gases and solid material; e) controlling the temperature in the reaction space by activating means for controlling the temperature of said oxygen-containing gas; f) causing said oxygen-containing gas to pass through said solid material, thereby causing said oxygen-containing gas to react with said solid material, whereby to produce fuel gases and ash; wherein, the composition and quality of said fuel gases are controlled by determining the desired equilibrium constant of the reaction of said oxygen-containing gas with said solid material and maintaining said desired equilibrium constant by controlling the temperature in the reaction space and the ratio of the waste to the oxygen-containing gas, which ratio is controlled by controlling the rates of feeding said waste and said oxygen-containing gas to said reaction space; and wherein, the feeding of the waste is done by providing two conduits, each comprising a piston at its end and disposed at right angles to each other and operating said pistons in a synchronized manner in which one of said pistons to carries out the forward stroke when the other of said pistons carries out its rearward stroke and vice versa, thereby allowing continuous operation of said apparatus.
