Kohlenstaub Heißluftofen für Schlackenmühle

Working principle Our pulverized hot air furnace is national patent.It consists of pulverized coal burner,oil ignition system, combustion system. The qualified pulverized coal is ejected into the furnace with high speed. Then the pulverized coal and air can be rotated with high speed while burning.the black fire head at the exit of the burner is very short,only 300-500mm. As the big negtive pressure zone is formed at the end of the flame, non burnout coal can be drawn into the negative pressure zone and burned again.so the coal burn-off rate can be up to 99%. Because the flame is very big from the coal burner, the temperature of the furnace can be controled below the ash melting point, so the slag can be well discharged. Our furnace adopts non-NOX burning technology, hot air furnace is designed with reduction and oxidation zone area and the coal burning can be formed like gas burning. Main features: wide coal flexibility.high automation.stable heat supply.convenient operation of oil ignition system its burn-off rate up to 99%, low pollution.less investment, return in a short cycle.Modol Heat capacity (kj/hr) dimension WHAJ-MP-1 4.18*106 3000*1500*4000 WHAJ--2 2*4.18*106 4500*2500*4200 WHAJ-FT-3 3*4.18*106 5800*2800*4500 WHAJ-FT-4 4*4.18*106 6000*3000*5200 WHAJ-FT-5 5*4.18*106 7200*3500*5500 WHAJ-FT-6 8*4.18*106 7500*4400*6200 WHAJ-FT-8 50*106 8000*5500*6480 WHAJ-FT-10 70*106 8716*5500*6600 WHAJ-FT-12 80*106 9520*5500*7000 WHAJ-FT-14 100*106 10050*6600*7800 WHAJ-FT-16 120*106 11000*6600*7800 WHAJ-FT-18 140*106 11000*7000*7800 WHAJ-FT-25 250*106 12500*7500*8500
