JRF Model Industrial Coal Combustion Hot Air Furnace for Grain/Coal
Combustion Hot Air Furnace
Working Principle
The furnace combines the combustion with the heat exchange, using
the latest indirect heating technology that the heat exchange is
taken place at the position of the high temperature in the furnace.
The smoke and the air go into the dierent channels, without any
pollution for the heating. The heat ef‑ciency rate is high (up to
60-75%).The temperature increase is fast. The furnace is small in s
ize, easy in the installation, reliable in the operation and low in
the price(making a comparison with one ton boile r, the price of
this system is only half price of the heating system for the
boiler).

Characteristics
The furnace uses the high temperature resistant method so that its
life is much longer than the life of the pipe arrangement hot a ir
furnace. The furnace uses the smoke and air longitudinal splashing
heat radiation sheets and the negative pressures smoke elimination
mode. There is no dust collected on the heat exchange position.
There is no need to carry out the cleaning. The heat feature is
stable. V arious coal and wood can be used as the fuel. The furnace
is equipped with the air leading device and the combustion is
complete. All the technical and economic indexes of the furnace
have reached the advanced level at home.
Material to be dried
The furnace is the versatile 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, s
eed,feed, fruit, de-watering vegetable. mushroom, edible fungus,
tremella, tea, tobacco leaf, other farming products, food,
medicine, chemical raw material ,light and heavy industry products.
