Abstract
A gas converter is disclosed, especially for the treatment, including dissociation, of gases produced in the pyrolysis of waste materials. The converter includes a feeder for airtight feeding of fuel from the upper region of the reactor tower to the bed of hot fuel, a gas outlet, and a slag removal system. The reactor tower is furnished at its lower end near the conduits for the admission of air and gases with a rotating distributor member. The feeder is provided by a bucket-wheel valve arrangement.
Claims13
A gas converter for subjecting a reactant gas produced by any of various thermal reactions, such as the pyrolysis of waste materials, to a high temperature cracking or dissociation reaction which comprises:
- a vertical, tubular reactor;
- means at the upper end of said reactor for introducing a particulate solid fuel;
- grate means at the lower end of said reactor for supporting a column of said fuel;
- an open-top annular slag pan positioned at the lower end of said reactor beneath said grate for receiving slag produced by the combustion of said solid fuel;
- a distributor member cooperating with the wall of said reactor to form an annulus through which slag can pass downwardly into said slag pan;
- means for introducing combustion supporting air and reactant gas to said reactor to an area adjacent the underside of said distributor member, said distributor member serving to direct a mixture thereof outwardly towards said annulus through which it passes upwardly into said solid fuel column;
- and means at the upper end of said reactor for discharging gaseous reaction products formed by the high temperature cracking of the reactant gas.
