MBL-H heat-exchange coal-fired hot air generator consists of MBL coal-fired machine, hot gas purifying chamber, and heat exchanger. Coal-fired machine supplies the primary heat. Raw (soft) coal is fed into the coal hopper through the coal feeder. The coal at a certain height is delivered by chain grate into the burning chamber of coal-fired machine. With the help of combustion fan, hot semi-coal gas produced by burning coal erupts from fire outlet of coal-fired machine and enters in hot gas purifying chamber. The chamber is built of fire resistant materials; hot semi-coal gas begins secondary combustion in purifying chamber. The dusts impact, aggregate and drop in the purifying chamber. Hot air from purifying chamber enters into flue gas inlet of heat exchanger, exchange heat with cool air in heat exchanger, hot air out from heat exchanger at the suitable temperature flows into dryer for drying. Temperature of hot air can be adjustable according to the demand. When hot air is supplied continuously, its temperature fluctuates between ±5. Cinder is discharged from the other side of coal-fired machine by deslagging machine. At present we have different types of heat-exchange coal-fired hot air generator to be selected by customers, which provide 0.25 to 20 million kcal, out temperature ranges from 50550(Based on the actual conditions). Advantages:1/ Meet the demand of environmental protection. No secondary pollution, good operating conditions.2/ Hot air is very clean, there is no influence on quality of product.3/ Total heat efficiency >754/ Temperature of hot air can be adjustable between 50 to 550. When hot air is supplied continuously, its temperature fluctuates between ±5.5/ Operate simply, adjust easily.6/ High security, there is no danger of explosion.7/ Equipment are durable, low cost of operation, easy maintenance. Hot air is very clean, whichcan beused todry or heat such materials as foodstuff, pharmaceutical intermediates etc.
