Title: Combustion equipment and method of preventing accumulation of flue ash
Inventor: MURAKAMI KAZUO
IPC: F23J3/00
Filed: 2000-01-27
Abstract: PROBLEM TO BE SOLVED: To improve reliability and maintainability by preventing the accumulation of ash in the tilted flue of combustion equipment. SOLUTION: When a flue on the upstream side of an electroprecipitator 6, which removes dust in exhaust gas generated by the combustion of fuel in a furnace, is a tilted flue 9 with ascending inclination along the flow of gas, the accumulation of the flue ash of the furnace is prevented by heated air using the flow path of air. The air is heated by mixing cool air taken out from the flue on the downstream side of a primary air ventilator or the forced ventilator 1 of powdered coal conveying air with hot air taken out of a flue on the downstream side of an air preheater 5, as the purge medium feeding flow path 10 used of purging system which blows out ashes accumulated on the bottom part of the tilted flue.  When the furnace 4 is heavily loaded, the reverse flow of the combustion exhaust gas containing sulfuric acid gas from nozzles 12 to purge piping 10 and the choking of nozzle 12 by the clogging of the nozzles 12 with intruded ash in the combustion gas into the nozzles 12 can be prevented by slightly opening a purging valve at the tilted flue 9 to predetermined valve travel on the upstream side of the electroprecipitator 6 arranged to the flue of combustion exhaust gas and flowing in the small amount of air from the nozzle 12 arranged inside the tilted flue 9.
