Characteristics of indirect gas hot blast stove

product overview

The furnace adopts a new indirect heating technology that integrates combustion and heat exchange, and exchanges heat at the high-temperature parts of the furnace body. Smoke and air go their separate ways, heating is absolutely pollution-free, with a thermal efficiency of up to 65-80%, fast heating, small size, easy installation, reliable use, and low price (compared to a 1-ton boiler, this heating system is only half the price of a boiler heating system). High temperature resistance measures have been taken, which greatly improves its lifespan compared to a tubular hot air stove. The output hot air temperature can reach 300 degrees Celsius, and a special design can output hot air temperature of 500-800 degrees Celsius. At the same time, the smoke longitudinal flushing heat sink and negative pressure suction smoke exhaust method are used, and the heat exchange part does not accumulate dust, does not need to be cleaned, and the thermal performance is stable It can use various types of coal or materials as fuel and is equipped with a secondary air inlet device for complete combustion The technical and economic indicators of this furnace have all reached the advanced level in China.

Characteristics of indirect gas hot blast stove

Product Features

This furnace is a universal hot air heating device, used in conjunction with various material drying equipment Widely used in grain, seeds, and feed Heating and dehumidification of fruits, dehydrated vegetables, shiitake mushrooms, fungus, Tremella fuciformis, tea, tobacco and other agricultural products, food, pharmaceuticals, chemical raw materials, and light and heavy industrial products It can also be used for heating various facilities and dehumidification in warehouses.

Application scope

Mainly suitable for drying materials that are not allowed to be contaminated, or for drying thermosensitive materials at lower temperatures. Such as milk powder, pharmaceuticals, synthetic resins, fine chemicals, etc. This heating device uses steam, thermal oil, flue gas, and other carriers to heat the air through various forms of heat exchangers.
The essential problem of indirect hot blast stove is heat exchange. The larger the heat exchange area, the higher the heat conversion rate, the better the energy-saving effect of the hot blast stove, and the longer the life of the furnace body and heat exchanger. On the contrary, the size of the heat exchange area can also be identified from the flue gas temperature. The lower the smoke temperature, the higher the heat conversion rate, and the larger the heat exchange area.
