[Applications]
  This fumace is supported for each kind of material drying equipment as a kind of general hot air unit, which is widely used for dehumidification of cereal, seed,feed and fruit, heating and wer extraction of vegetables, mushroom, Jew's-ear, tea, tobacco, food, pharmaceutical products, chemical raw materials and light and weight industrial products, as well as for heating of various facilities and dehumidification of warehouses.

[Working Principle]
  Combining burning and heat exchange as a whole, this furnace adopts the novel indirect  heating technology of performing heat exchange at high ternperature position of the furnace, inside which, smode and air flow separately, heating has no contamination, thermal efficient reaches 60-75%, therefore, it features speedy temperature rise,comact dimension. convenient installation, reIiabIe operation and Iower cost(only half of that by boiler heating system

note:

1. The outout temperature means the raised ternperature from 20'C of input temperature.
2. lf the output temperature is high than 300'C. the inner wall of furnace is made of raw
materials, such as stainless and so on that can withstand high temperature. The price should be kiscussed face to face.
3. The fuel value of coal is calculated based on 5500kcal/kg
