Title: Swirling melting furnace
Inventor: TANIGUCHI YUKIHISA
IPC: F23G5/32
Filed: 2000-04-03
Abstract: PROBLEM TO BE SOLVED: To increase the recovery rate of molten slag and prevent environmental pollution by substantially completely melting char, burnt ash and the like in a swirling melting furnace. SOLUTION: Two nozzles 2 are disposed on a trunk of a swirling melting furnace 1 in the upstream and downstream directions with a given interval therebetween. Uncombusted carbon, such as char, burnt ash or the like is blown into the furnace 1 from the nozzles 2. The diameter of an exit 6 of the furnace is rendered 0.6 or less times of the inner diameter of the furnace 1, and the distance between the centers of the two nozzles is rendered two or more times of the inner diameter of the nozzles. Thus interference between the jets blown out from the two nozzles 2 can be prevented. In addition, since a gas flow is inversed at the exit 6 and reaches the upstream portion, dwell time of char (ash) in the furnace can be prolonged.  Further, since it became possible to keep the temperature in the furnace at the melting temperature or more of the particles, the amount of molten slag can be increased.
