Hot blast stove combines combustion and heat transfer as one of the latest indirect heating technologies for heat transfer at high temperature of the furnace body. Smoke and air are in different ways. The heating system has absolutely no pollution, high thermal efficiency (up to 60-75%), fast heating, small size, convenient installation, reliable use and low price (compared with a ton of boilers, the heating system is only equivalent to a boiler). Half of the price of the heating system. 二、性能特点：
Two, performance characteristics:
High temperature resistance measures have been adopted, which greatly prolongs the service life of the hot blast stove compared with the tubular stove. Longitudinal flue gas scouring heat sinks and negative pressure smoke exhaust mode have been adopted. There is no dust deposit in the heat transfer part, no need to clean up, and the thermal performance is stable. All kinds of coal or firewood can be used as fuel and equipped with two intake devices for complete combustion. All technical and economic indexes of the furnace have reached the leading level in China.
Three, adapt to the material:
The utility model is a universal hot air device and is matched with the drying equipment of various materials. Widely used in food, seeds, feed, fruits, dehydrated vegetables, mushrooms, agaric, tremella, tea, tobacco and other agricultural products, food, medicine, chemical raw materials, light and heavy industrial products, heating and dehumidification, but also for various facilities and warehouse dehumidification.
The four major environmental advantages of hot stove are:
1, energy saving
An index in hot blast stove is called heat exchange area. When the heat transfer volume is constant, the larger the heat exchange area, the higher the heat transfer efficiency of the stove, and the more energy-saving it will be. The multi-return heat exchange technology is adopted in our hot blast stove, which makes the travel of flue gas in the stove longer, the number of heat exchanges with the wind more, and the area of heat exchange larger, so as to improve the thermal efficiency and save coal consumption.
The hot blast stove adopts negative pressure combustion and positive pressure heat exchange. The positive pressure heat transfer of hot blast stove is the method of blowing into the furnace, while the negative pressure heat transfer is the method of sucking the induced draft fan out of the furnace. Even after many years, there is damage somewhere in the furnace, because the air path is positive pressure, and the smoke path is negative pressure, the wind will leak into the smoke path. Then the fire will be weakened, in the burned position, because the wind outflow, the temperature of this part will be reduced, will delay the speed of damage. This is what we call damage self repair. Because smoke can not enter the wind, and more importantly, it ensures the safety of breeding.
Hot blast stove does not need radiator, which reduces the heat consumption of secondary heat exchange and does not need to worry about the hidden dangers of scale and ice. Each hot blast stove has its own fully automatic temperature control equipment, which only needs manual coal feeding.
4, long service life
The life of hot stove is mainly determined by the anti burning technology of the furnace. The high-temperature heat exchange part (heat-resistant tube) in our furnace adopts the seamless steel pipe specially designed for hot blast stove, which can be used for a long time at 1300 C without damage.
