Product application
Hot flue gas fluidized bed hot air furnace can supply heat for such equipments as rotary drier, vertical drier, hammer drier, indirect drier, dry-grinding plants for slag micro-powder, air swept coal mill or dry-grinding plants for pulverized coal, fertilizer granulator, powder drying tower waste-heat power generation for concurrent heating material mixing & seasoning, and also to dry and bake such industrial raw materials or products as slag, clay, filthy mud, carbide slag, complex fertilizer, industrial plaster, plasterboard, fine iron powder sulfur ore concentrate, laterite ore, siderite, Zinc leaching residues coal dust and coal slime.
Working characters
1.Wide application for fuel.
It can use raw coal whose heating capacity over 6270KJ/Kg, or various bituminous coal, anthracite, lignite, and even gangue whose heating capacity is 1500Kcal/Kg.
2.Temperature in chamber is about 1000 °C, outlet temperature of chamber is about 850 °C, stable and even.
3.High combustion efficiency, coal burn-off rate: 99%, thermal efficiency rate: 95%, carbon content in ash: 2%;
4. Non-coking, suitable for making cement mixture and filler for other building product;
5.Easy ignition, long-time banking fire, intermittent banking fire time up to 16~48 hours, no need to re-ignite when restarts the banking fire.
6.Adjustable outlet temperature of the hot gas, convenient heating gas pipeline.
7.Clean burning, low NOX flue gas, desulfurization inside furnace, and solid sulfur in coal slag.
8.Achieving automatic PLC control, low working temperature.
9.Long service life, less wearing parts, low maintenance expense
Combustion way
1 broken coal particles with diameter below 10mm are sent evenly into the fluidized bed of the furnace chamber with coal feeder.
2The high pressure blasts from the blower are injected by the equal pressure bellows into the furnace chamber through nozzle button pores on the distributor. The blasts from all directions from the air bed to support coal particles and charging material for fluidized boiling combustion.
3The coal particles and coal slag crash and split mutually till burning into cinders in high temperature.
The features of our combustion way:
1.Large contact area between air and fuel;
2.High relative motion speed;
3.Long burning of fuel in fluidized bed;
4.Fast burning speed, high burning rate;
5.Energy saving and environment protection.
