■ JRF Series Coal Fuel Hot Air Furnace manufactured  by our company was designed by China Agricultural Enginnering  Institute, Through five  times  improving,  its quality  is  in  the  leading position  in China,  It had been approbated as China patent product on February 2.1989. The  furnace  integrates  combustion  and  heat exchange  in  its  one body and adopts  the  newest  indirect  heating  technology with  the temperature  increase  is  fast, The  furnace  is  small  in  size.  easy  in installation, The smoke and the air go into the different channels with any pollation  for  the heating,the heat efficiency  rate  is  high  (up  to 65-80%),  reliable  in operation,  cheap  in price  (compared with 1  ton of boiler, its price of heating system  is half only  ). Being adopted  the measure of high temperature resistant its life is longer than calandria type hot air  furance greatly. The  temperature of  sent hot air will be 300°C.  If adopt special design  ,the  temperature of sent hot air will be  500°C-800°C. Meanwhile  being adopted  vertical   washing heat sink and negative pressure mode  to  remove smoke,  the place of heat exchange does  not accumlate dust, so  it  does not need  to clean and  its  thermal performance  is  stable.  It  can  use all  kinds of coal or dieseloil as  fuel.Being equipped secondary air  in devices, its combustion is fully ,All technical and economic indexes are in leading place domestic.

■ The  furnace  is  the universal hot air equipment.  It  is used with other equipment  for drying  various materials. The  furnace  is widely  used for the heating and moisture removing for the grain, seed, feed, fruit, dehydrated  vegetable, mushroom, agaric, white fungus, tea, tobacco leaf, other  farming products,  food, medicine, chemical  raw material, light and heavy industry products.

■ At present  the  furnace has  ten varieties and  three series,  Its heat  to be output:

■ Remark:
1.The output temperature means the raised temperature from 20℃of input temperature.
2.If the output temperature is high than 300℃. The inner wall of furnce is made of raw materials, such as stainless steel and so on that can withstand high  temperature. The price should be discussed face to face.
3.The fuel value of coal is calculated based on 22990 kj/kg
4.The layout of equipment will be provided as request.
5.The output temperature will be 500℃-800℃when it is designed specially. The price should be discussed face to face.
