China Low Cost China Quality Coal Fired Hot Air Furnace

Description:
GMF series coal-fired hot air furnace is a kind of hot air generator that burns coal directly. It has such advantages as high efficiency, energy saving, cleanness and environmental protection, it is widely used in the industries of chemistry, building materials, ceramics, metallurgy, feedstuff, fertilizer and so on, nowadays it is the first choice to replace oil-fired and gas-fired hot air generator.
Work Principle:
GMF series coal-fired hot air furnace consists of coal-fired machine, coal-fired chamber, and heating 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 coal-fired chamber,. The chamber is built of fire resistant materials. The particles impact, aggregate and drop in the coal-fired chamber. Clean hot air from heating exchanger at about 1000 then mixes into a certain amount of cool air, the mixture at the suitable temperature flows into dryer(such as spray tower, rotary kiln, oven, drying house, flash dryer, fluidized bed etc.) 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.
Product Characteristics:
1. Meet the demand of environmental protection.
2. Save energy, heat efficiency can be reach to 95.
3. Hot air is very clean, purity, not any dirty
4. Temperature of hot air can be adjusted easily, 60~1000 adjustable.
5. Equipment is durable, low cost of operation, easy maintenance.
Application:
It is widely used for drying or heating in chemical industry, ceramics industry, fertilizer industry, water purifying agent industry, building materials industry and so on.
