Second, the heating stove:
1. The fully automatic coal-fired hot blast stove adopts the indirect heating technology that integrates combustion and heat exchange, and uses the high temperature part of the furnace body for heat exchange. The flue gas and the air go their own way, the heating is pollution-free, the thermal efficiency is as high as 65-80%, the heating is fast, the volume is small, the installation is convenient, the use is reliable, and the price is low (compared with a 1-ton boiler, this heating system is only equivalent to a boiler half the price of the heating system). High temperature resistance measures are taken, so that its life is greatly improved compared with the tube-type hot blast furnace, the output hot air temperature can reach 300 degrees Celsius, and the output hot air temperature can reach 500-800 degrees Celsius with a special design, and the flue gas longitudinally washes the heat sink and Negative pressure suction smoke exhaust method, no dust on the heat exchange part, no need to clean, stable thermal performance. Various coals or materials can be used as fuel, and it is equipped with a secondary air inlet device, which can burn completely. The individual technologies of this furnace The economic indicators have reached the domestic leading level.
The furnace is a universal hot air heating device, which is used in conjunction with drying equipment for various materials. It is widely used in food, seeds, feed, fruits, dehydrated vegetables, shiitake mushrooms, fungus, white fungus, tea, tobacco leaves and other agricultural products, food, pharmaceuticals, etc. Heating and dehumidification of chemical raw materials, light and heavy industrial products. It can also be used for heating of various facilities and dehumidification of warehouses.
2. The composition of the equipment:
The main body of the hot blast stove, the chimney, the waste heat recovery device of the chimney, the combustion-supporting device, the fan, the electronically controlled temperature measuring equipment, the air inlet duct, the return air duct, and the ventilation device, etc.
3. The working principle of the equipment:
The hot blast stove produces pure hot air with a temperature as high as 180°C. The metal pipe directly enters the space required for heating through the air outlet of the hot blast stove (the rear part can be ventilated with a canvas bag). Adjust the air volume and temperature of the space (additional valve adjustment if local high temperature is required), and the main fan on the top of the hot blast stove recycles the waste heat from the chimney and the air in the required heating space. The combustion-supporting device reasonably adjusts the oxygen intake of the hot blast stove, controls the size of the flame, and controls the temperature of the air outlet; add an automatic humidification device for humidification.
4. Features of the equipment:
The rotary heat exchange method is adopted, and the heat energy conversion efficiency is high; the chimney heat energy recovery device has a high heat energy utilization rate.
Pipeline air supply is used to heat the air and send it into the room. The air is fresh and the temperature is uniform; no water is used, there is no hidden danger of scale and freezing, and there is no need to install additional radiators, and there is no secondary heat exchange; the five sides of the hot blast furnace body are all There is 50mm thickness of excellent glass wool insulation, which reduces the loss of heat, and the overall heat utilization rate reaches more than 90%.
Adopt more excellent negative pressure oxygen-enriched combustion technology, not picky about coal or other fuels, no matter what kind of coal is used, it can ensure transparent combustion, and completely avoid the uneven furnace temperature, impermeable combustion, and flue gas caused by positive pressure combustion. defects such as spillage and partial burning; walk at the starting point—from burning.
The heat exchange part in the furnace – the refractory tube is manufactured by our company’s patented anti-corrosion technology, which can be used at a high temperature of 1450 ° C for a long time without damage, so that the trouble-free operation of the hot blast stove has been improved by 3-5 years, and the overall service life has reached 8 years above.
The whole set of equipment saves investment, is easy to operate, safe and reliable, basically has no maintenance costs, is easy to install, and has excellent heating effects. It is an ideal heating equipment for offices, workshops, flower greenhouses, vegetable greenhouses, poultry breeding and other industries.
5. Coal-fired saving: This method of coal-fired is less than 50% of that of ordinary hot water boilers and steam boilers
6. Use environment: offices, painting workshops, textile workshops (with automatic humidification), flower greenhouses, vegetable greenhouses, poultry breeding greenhouses, etc.
