A method for rapid activation SLEP Furnace, characterized in that: (1) increase half-heated air into the furnace volume, the heating temperature was subsequently raised by a half furnace 900 ° C to 950 ° C; air is added through the air duct by the blower SLEP semi heating furnace, the combustible gas activation resulting combustion generates heat to increase the furnace temperature, the furnace body in a safe range, to adjust the frequency of the blower, blower speed control, to control the amount of air into the control furnace temperature; by adjusting the blower the frequency and size of air valve opening, so that the furnace temperature was controlled at SLEP .950 0C; (2), changing the air distribution SLEP furnace waste heat boiler location, to improve the utilization efficiency of the exhaust gas, so that the steam production is increased; the furnace exhaust SLEP position with the wind exhaust duct is provided in the middle thereof, using…
