ZLRF Series Hot Air Furnace

ZLRF series metal fuel-oil indirect heating hout-air furnace, a hot-air heating device (heat efficiency could reach 65%-85%), which is designed by ourselves The outlet hot-air temperature could be 300. Moreover, if special design, the temperature will reach 500~800. Fume and air take each pipe so that the air after be heat transferred will be clean. It can be matched with all kinds of drier and is widely used to heat and dehumidify the agricultural products such as foodgrain, seed, fodder, fruit, dehydrated vegetables, mushroom, agaric, white fungus, tea-leaves, tobacco leaves, etc. and food, pharmaceuticals, chemical raw materials, etc.

Applications:

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, 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.

Features:

The furnace uses the high temperature resistant method so that its life is much longer than the life of the pipe arrangement hot air 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. Various 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.

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 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 low 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).
