JFR Series Coal Combustion Hot Air Furnace

Description

JFR Series Coal Combustion Hot Air Furnace

WORKING PRINCIPLE

The furnace combines the combustion with heat exchange in one and using the latest indirect heating technology that heat exchange is taken place at the high temperature position of the furnace. The smoke and air are divided to different air ducting to avoid the pollution on heating process. The heat efficiency rate is high (up to 60-75%). The temperature increase is fast. The furnace is easy for installation and reliable for operation, and the price is low (compare to the one ton boiler, the price of this heating system is only half of the price for boiler heating system.).

FEATURES

This furnace has the high temperature resistant so that its using life is much longer than the pipe arrangement hot air furnace. And it uses longitudinal splashing heat radiation fin and the negative pressures smoke elimination method. There is no dust collected on the heat exchange position so it’s no need to carry out the cleaning. The heat feature is stable. Various coal and wood can be used as the fuel. The furnace is equipped with the air leading device to ensure the combustion is complete. The technology of this furnace has reached the advanced level in China.

APPLICATION

This furnace is versatile hot air equipment. It is used as a heating device to the drying equipment. It is widely used for the heating and moisture removing for the grain, seed, feed, fruit, de-watering vegetable, mushroom, edible fungus, tremella, tea, tobacco leaf, and other farming products. It also used for the products in food, medicine, chemical, light and heavy industries.
