IPC: F23G5/46
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To perform a complete combustion without discharging smoke to the outside by a method wherein one end of a circulating current pipe being connected to a smoke- discharging cylinder, is opened at an outside air inlet, and the other end is extended and introduced to a space between a grate of a combustion chamber, and a water tray in a refractory housing, by inserting a motor fan. SOLUTION: Smoke which generates accompanying the combustion of waste, is introduced again, together with soot, to a space between a grate 2 of a combustion chamber 2 and a water tray 10 in a refractory housing 8, from a smoke discharging port 3 and a smoke discharging cylinder 12 through a circulating current pipe 13 on the outside. In this space 16, the soot portion is mixed with steam which generates from hot water in the water tray 10, and falls in the water tray 10. Then, one part is fed into the combustion chamber 2 again by the grate 6, together with the outside air, and the other rises in the refractory housing 8 by a convection phenomenon in the path, a forcible circulation action by a motor fan 15, and a rising air current which is caused by a hot water evaporation action of the water tray 10. Then, the ascended part is joined with the smoke of the combustion chamber 2 by a communication port 12a, and introduced to the smoke discharging cylinder 12 while doing so, and is discharged to the circulating current pipe 13 again.
