The high clean direct coal fired hot air furnace is mainly composed of a coal burner, a high temperature purifying room, a mixing air chamber and a control system. Its main characteristics are high hot air cleanliness, low running cost , safe and convenient operation. The heating capacity of a single hot is 500,000~20,000,000 kcal / h, and the maximum output temperature is about 1000 degree centigrade. It can be connected to spray tower, rotary kiln, fluidized bed, air dryer, drying room, oven and other drying equipment to dry the product.
Technical characteristics:
(1) full combustion, no black smoke in hot air and clean operation environment；
(2) hot air clean and high dust content of 30 ~ 120mg/Nm ;
(3) thermal efficiency >95%;
(4) hot air temperature adjustment is convenient, adjustable below 1000 degrees, and continuous heating air temperature stability is + 5 egree centigrade；
(5) the operation and the adjustment is very convenient.
(6) the safety of equipment is high and there is no danger of explosion.
(7) the equipment has strong durability, low running cost and simple maintenance.
(8) all hot air enters the drying plant, and the production process does not increase the discharge port.
