Technical introduction

Fluid bed hot air furnace (boiling furnace):Coals are crushed into particles which is about 1 to 3 mm. Then the coal can be burnt in the furnace. Coals are sent to furnace combustion chamber uniformly by coal feeder. Then coals are injected into furnace body by high-pressure air produced by blower and orifices distributed on air distributor. Air cushion produced by air scattered from various directions hold coal particles and furnace materials are burnt in fluidized state. Coal particles and coal slags turn repeatedly under high temperature and mutual friction is formed between materials. Then, materials collide and are decomposed until they are burnt off. This kind of combustion method is characterized by large contact area, high relative speed, long staying time, fast combustion speed and high burn-off rate. Therefore, the aims of saving energy and protecting environment are realized. This product has been widely applied to industrial kilns and boilers for many years.
This kind of boiler can be used for rotary dryer, vertical dryer, hammer type dryer, indirect dryer, small slag powder production line, air swept coal mill, coal powder mill and fertilizer pelleting production line. It has been widely applied to drying and calcination for industrial raw materials and relevant products, such as: Slag, clay, coal, carbide slag, compound fertilizer, industrial gypsum board, iron powder, sulfur concentrate, late rite, side rite, zinc leaching residue etc. 


Product performance:
1. Wide adaptability: it can use various coals such as bituminte, anthracite, lignite, sawdust and coal gangue.
2. The temperature of furnace is about 1000 degree centigrade; the temperature of furnace outlet is about 850 degree centigrade; running temperature is very uniform; heat support is very stable;
3. High combustion efficiency; the burn-off rate of coal powder can reach about 98%; thermal efficiency can reach over 95%; the carbon content of ash is lower than 2%; it is not easy to produce cokes; good activation;
4. Easy to ignite; the time used for banking fire is long; discontinuous banking-fire time can reach to 16 to 48 hours. Start after banking-fire, there is no need for re ignition.
5. The temperature of flue gas outlet can be adjusted; the outlet for heat support is convenient and flexible.
6. Clean combustion; low NOX content in flue gas; can realize desulfuration in furnace which can make sulfur enter furnace slag in solid state;
7. The system can realize PLC automatic control methods; low labor intensity;
8. Long service span for furnace body; less wear parts; less maintenance cost;
