Industrial coal-fired boilers include chain grate boilers and circulating fluidized bed boilers. The efficiency of circulating fluidized bed boilers can reach more than 84% and has the advantages of low nitrogen, environmental protection, high efficiency and low pollution. It is suitable for large-scale central heating and cogeneration of heat and power. The chain grate coal fired boiler efficiency is more than 77%, and the investment of boiler equipment is lower. It is the most widely used type of coal-fired boiler.
The water wall of ZOZEN coal-fired boiler adopts close drainage water wall pipe, which solves the problem that the temperature of the outer surface of the furnace wall is generally higher than the national standard due to the radiation of high temperature flue gas, reduces part of the heat loss and improves the thermal efficiency of the boiler. Reasonable air conditioning device can achieve precise air distribution and improve combustion efficiency. The thermal efficiency of ZOZEN coal-fired boilers can reach more than 82%. All kinds of boiler produced by ZOZEN Boiler are developed through careful design, and their thermal efficiency is generally higher than that of similar products.
