Abstract:
1. An incinerator comprising: a cylindrical combustion chamber; and a plurality of combustion-promoting blast pipes each of which is disposed so as to project from one location on an inner wall of the combustion chamber, extend in a vertical direction thereof and exit to exterior from another location, wherein the combustion-promoting fluid blast pipes are of a triple-pipe construction, each comprising an air-supply pipe, a steam/gas-supply pipe which is provided concentrically outside of the air-supply pipe for supplying steam or combustible gas, and a water pipe which is provided concentrically further outside thereof for protecting the air-supply pipe and the steam/gas-supply pipe from heat, and a plurality of nozzles are provided on each of the combustion-promoting fluid blast pipes, the nozzles being positioned facing in one circumferential direction of the combustion chamber so that a combustion-promoting fluid blown out from the combustion-promoting fluid blast pipes forms a swirling flow within the combustion chamber; and the air-supply pipes and the steam/gas-supply pipes in the combustion-promoting fluid blast pipes are connected respectively to a high-pressure air-supply source and a steam/gas-supply source, so that air and either steam or combustible gas or both can be blown from each of the supply sources into the combustion chamber as the combustion-promoting fluid via the combustion-promoting fluid blast pipes.
