Summary :
I plant the JRF series of vertical tube metal body of indirect heating hot air furnace products, after several upgrades to achieve the leading level in the country. The furnace integrates combustion and heat exchange into a whole, and the heat transfer of the furnace body at high temperature is the most new heating technology. The smoke and air each go their way, heating absolutely no pollution, high thermal efficiency (up to 60-75%).
Heating up fast, small size, convenient installation, reliable use, and low price (compared with a ton of boiler), the heating system is equivalent to only half the price of the boiler heating system. The high temperature resistant measures, so that the service life is greatly higher than that of tubular furnace, hot air temperature output up to 300. C. also introduces flue gas longitudinal flow heat sink and negative pressure suction exhaust, heat exchange part no dust accumulation, no need to clean, stable thermal performance. Can use all kinds of coal or firewood for fuel, and is equipped with two times into the wind device burning completely. The technical and economic indicators of the furnace has reached the leading level in the country.
The furnace is universal hot air heating device, supporting the use of drying equipment and various materials, widely used in food, feed, seed, fruit, dehydrated vegetables, letinous edodes, fungus, tremella, tea, tobacco and other agricultural products, food, medicine, raw material in chemical industry, heavy industry products, heating and dehumidification, can also be used for various facilities the heating and dehumidification warehouse etc..
At present, the furnace has been formed series, the output of heat （1.04-0.25)×108J/h，(1.67-0.29)×108J/h,(2.5-3.34)×108J/h,4.18-6.27)×108J/h,(10.45-1.25)×108J/h,(22.9-25)×108J/h,41×108J/h 66.8×108J/hEight products, such as the formation of the three series.
