4 tph high-efficiency WNS series gas-fired steam boiler project for the coal mining industry

Guizhou Shuicheng Mining Co., Ltd. is a large-scale enterprise group focusing on the coal production and processing. Its business also covers the chemical processing of coal, electric power, coal machine manufacturing, etc. The company's mining area is mainly composed of the Shuicheng mining area and Zhina mining area, with rich geological reserves, complete coal types and good coal quality. Its main coal products include washing mixed coal, sieving mixed coal, anthracite and smelting refined coal, which are the ideal coal types for the electric power, chemical, building materials, metallurgy and other industries. This time, in order to further improve the coal product quality and production efficiency, Shuicheng Mining ordered a set of high-efficiency WNS series gas-fired steam boiler from ZOZEN, and achieved the desired effect of energy saving and emission reduction.

ZOZEN WNS series gas-fired steam boiler is a typical kind of high-efficiency and energy-saving steam boiler. The boiler proper adopts the wetback structure. With the advanced low-NOx burner, the boiler can achieve the high efficiency, low backpressure and low-emission operation. The boiler also has sufficient steam storage space and heating surface, so it can produce high thermal power and high-quality steam with high efficiency. Besides, ZOZEN installs the energy-saving devices such as the economizer and condenser at the end of the flue gas duct to lower the exhaust gas temperature to 60°C and below, which can reduce the heat loss and further improve the thermal efficiency. It is understood that the thermal efficiency of ZOZEN WNS series steam boiler can reach over 98%. It has been awarded the honorary title of energy efficiency star for many times and has been favored by users in various industries.
