Descriptions

YRF-A direct combustion type oil fuel (gas) hot air furnace: amount of supplied heat is 300000-15000000 kcal/h; the temperature of supplied air is 150-750℃ (adjustable); thermal efficiency >95％; operation life be over 10 years. And adapt two times air distributed technology, etc; the smoke is pure and clean. It has been used successfully for drying many materials such asreinforcing silica, kaolin, terra alba,  magnetic powder, etc. 

YRF-B heat exchange type oil fuel (gas) hot air furnace: for furnace type with below 8000000 kcal/h of amount of supplied heat, heat exchange chamber and combustion chamber forms one integration. Material is refractory brick and 20g, temperature of supplied air be below 350℃ . For furnace type with 1000000-10000000 kcal/h of amount of supplied heat, heat exchanger and combustion chamber are separated, material of heat exchanger is 20g, temperature of supplied air be below 350℃, material of heat exchanger is SUS304; if temperature of supplied air be below 550℃; material of heat exchanger is 310S, temperature of supplied air be below 750℃. Thermal efficiency of YRF-B heat exchange type oil fuel (gas) hot air furnace >80％ and its discharge is up to grade. 

The burner of YRF-A, YRF-B oil fuel (gas) is made by Germany or Italy. It iscontrolled by computer and its use is safe and its operation is convenient.
