More practical in drying coal equipment is large drum dryer, high temperature and strong drying, drying coal is even and wet, suitable for a variety of coal drying, pulverized coal dryer is also a drum drying structure, with technology And the environment changes, the new heat source form is widely and widely applied, and the environmental impact assessment is adopted to avoid the coal ban and ensure the continuous operation of the pulverized coal drying line.
The new form of heat source for pulverized coal dryers is mainly the form of fuel and the change of the introduced heat medium. The traditional pulverized coal drying heat medium is mainly formed by coal-fired heating. The main advantage of coal-fired heating is the low cost, mainly the circulating application of drying pulverized coal, and the current environmental protection form, coal-fired supply The heat is gradually being eliminated. The new situation is mainly new clean fuels, such as natural gas, coal gas, biomass fuel, etc., and the heat source equipment also forms gas-fired burners, gas generators, biomass burners and the like due to different fuels.
The transformation of the form of heat source comes from the change of China's energy structure, on the other hand, it is also the inevitable requirement for the nationalization and deepening of China's hot environmental protection. The pulverized coal dryer adopts a new type of heat source, which can maintain high efficiency, environmental protection and continuous production, thereby promoting the high-quality development of coal cleanliness, coal drying and upgrading, and improving the coal market price and application.
