Related Product Searches:Coal Furnace,High Quality,Coal furnace, hot air furnace,JRF
Principle of workThe furnace is an universal . It can be used with many kinds of dryers.The furnace 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, other farming products, food, medicine, chemical raw material, light and heavy industry products.
ApplicationThe 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 different channels, without any pollution for the heating. The heat efficiency rate is high (up to 60 - 75%). The temperature increase is fast. The furnace is small in size, easy in the installation, reliable in the operation and Iow in the price (making a comparison with one ton boiler, the price of this system is only half price of the heating system for the boiler.).

Note: The environmental temperature standard takes 18±2.The thermal value for the coal takes 5500kcal/kg for the calculation.
The hot air temperature in the table is decided according to the air output. When the temperature is more than 300,the internal wall will be made from stainless steel ,but its price is different.
