1, Heating method: hot air flue and heating simultaneously in two ways. Start from the furnace flue length wear along Room 1/2 above the heater bags worn smooth from the furnace room. 2, energy: (a) negative pressure combustion technology, to ensure that coal combustion transparent. Allow energy from the burning begins. (2) long composite stove flue, flue gas heat utilization above 95% 3, and durable: Use high-quality refractory furnace at 1400 ℃ for long-term use at high temperatures without damage.
