Injection machine is a new type of coal auxiliary equipment, through special mechanical design, can improve the efficiency of pulverized coal combustion, in order to save fuel, improve the combustion rate of the role. Injection machine is also called coal powder spraying machine is a new type of coal, coal equipment, can greatly reduce the amount of coal, to eliminate the waste of coal!
Injection machine is the new coal-fired equipment, mainly used for industrial boilers, heating boilers, thermal oil furnace and other various types of boiler, can replace fuel, gas and electric heating heat energy equipment, which can save 50% of energy. Special coal boiler heating temperature is too high; heating time; excessive air distribution inside the furnace; the furnace negative pressure suction air heating furnace; low temperature.
This product can greatly reduce the labor intensity of personnel, has the characteristics of reducing costs, improving economic efficiency, to achieve environmental indicators.
Injection machine always should pay more attention in use:
1, before ignition, must clean burning platform, dianwang wood, the first to open a small burner for 4-5 minutes, then open the pulverized coal burner, should be appropriate to control the coal feed quantity, increases gradually, under normal circumstances, the flame is red with yellow, pulverized coal burner is complete.
2, when the ignition with bituminous coal, when the temperature rose to 700 degrees, or other available anthracite coal.
3, the furnace temperature to 400-500 degrees, in order to adjust the furnace temperature difference, large nozzle block brick can be gradually reduced.
4, coal should go through the crusher, make the coal particle size of not more than 2 cubic centimeters, coal to dry, no iron into the machine to prevent accidents.
5, coal powder machine rotating part must be lubricated, if found abnormal sound, should immediately stop check, running to keep the normal transportation quantity of coal. No empty, to prevent the cold air into the furnace temperature effect.
6, coal powder machine is shut down, should close the funnel and gate, to be hit in order to stop coal. When starting to be empty in normal operation, then open the funnel.
As a new type of coal injection coal, coal equipment, mainly used for drying, annealing, tempering, steam boiler etc.. The first injection machine for handsome sites such as: plant, foundry, steel rolling mill, steel mills, cement plants, all coal-fired boiler plant industry, alternative fuel, gas and electric heating thermal energy equipment, thereby saving energy 40-50%. Injection machine can greatly reduce the labor intensity, reduce the cost and improve the economic benefits etc..
Injection machine has convenient ignition furnace temperature, easy control, stable product quality, production characteristics. The machine has the advantages of simple structure, compact structure, convenient installation and maintenance, reduced labor intensity and reduced energy consumption. The first handsome coal injection has the advantages of high thermal efficiency, energy saving and increasing production, no waste gas discharge, and the production is not affected by the rainy weather, bring significant benefits to the factory.
The principle of injection machine: first coal grinding roller and grinding into the area, grinding roller rolling mill in coal under. The grinding roller loading force is an important parameter of the coal mill run safely and economically with roller loading force, pressure roller grinding, the fineness of the pulverized coal, coal output increased, coal particle characteristic coefficient n increases, the milling coal consumption decreased, but the coal mill equipment vibration, wear quickly, reduce the service life of the mill part. First, the machine has a handsome coal supply multi-stage crushing, transportation and other processes, features a complete. With a uniform, thorough combustion, no black smoke, etc., both to save 50% coal-fired, but also meet the requirements of environmental protection, is the enterprise to reduce costs, reduce pollution indicators essential products. Raw coal through the machine a series of grinding process into a very fine powder, by the wind blade to 150 mm water column of the pressure into the furnace in the suspension of combustion to achieve the purpose of complete combustion
