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.Working Principle:GMF series hot air generator system 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.Structure: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 dirty4. 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.Technical parameter:TypeHeating value×104kj/h(×104kcal/h)Temperature (°C)Coal consumption (kg/h)Heating efficiency (%)Working typeTotal weight (t)Install area (m2)GMF3012650-45085-95≥65Mechanical feeding hand out the slag8-106×10GMF6025150-450160-180≥6513-157×10GMF8033450-450210-230≥60Mechanical feeding the slag machinery16-188×10GMF10041850-450280-30019-209×11GMF12050250-450350-37021-2310×12GMF20083650-450500-55028-3013×15Company Information:   FAQ:1.
