The device adopts a new fin structure technology with low thermal resistance and high heat transfer coefficient. The heat exchange efficiency is 20% higher than that of traditional equipment. The use of self-developed heat-insulated combustion chambers improves the utilization of coal and can save energy by more than 15%. In the high temperature zone, high temperature resistant special metal materials are used as liners, and the service life is more than double that of similar products. The device's heat output temperature reaches 300°C to 500°C, and the thermal efficiency is over 85%. At the same time, because the equipment uses coal, oil, gas, vegetation, straw, waste, etc. as fuel, the indirect heat exchange can directly output clean hot air, which can replace the current steam heat exchanger, heat transfer oil heat exchanger and electric heaters and other traditional model. It is understood that hot air furnaces are widely used as important drying equipment in the chemical, metallurgical and food industries.
New type hot blast stove in North China drying plant is highly energy efficient
Hengshui City, Hebei North China Drying Equipment Factory developed a new generation of high-efficiency energy-saving hot stove, with a large amount of heat, thermal efficiency, low energy consumption, long service life and other characteristics. At present, the hot blast stove is not only popular in the domestic market but also indirectly exported to the international market.
