PROCESS AND APPARATUS FOR PRODUCING FUEL GAS

摘要

In a process for producing fuel gas from domestic and industrial waste, old tires, plastic scrap, paint and varnish sludges, light shredded automobile scrap and the like, the waste is pyrolyzed in the absence of air in a pyrolysis device. The volatile pyrolysis products formed in the pyrolysis are gasified with addition of air or oxygen-enriched air to form the fuel gas. The volatile pyrolysis products are introduced into a free space reactor by means of subatmospheric pressure. The gasification of the volatile pyrolysis products is carried out in the free space reactor. The volatile pyrolysis products are gasified using their own heat of reaction.
