内启闭无泄露给粉机

Powder feeder with internal gate and leakproofness

NGF型内启闭无泄漏给粉机是火力发电厂锅炉燃烧系统主要的给粉设备，能把煤粉连续、均匀地供给锅炉燃烧系统。通过调整叶轮转速调节给粉量，从而调整锅炉燃烧状态，保证锅炉稳定、安全运行，也可用于建材、冶金、化工等行业的给粉系统。

该产品采用国际领先技术，其专利技术为我厂独有。为方便用户的不同需要，我厂可配套变频调速控制系统。

该机可与冲击式流量计配套使用，以实现给粉量的瞬时计量和累计计量，提高燃烧效率，降低飞灰中的可燃物。

Model NGF powder feeder with internal gate and leakproofness is a major pulverized coal feeding equipment in combustion system of power plant to feed coal into boiler continuously and evenly. The feed quantity can be adjusted by means of adjustment of vane rotating speed so that the boiler can run stably and safely.

This feeder can also be used in material feeding system of building metellurgy and chemical industries.

The instantaneous feed quantity and accumulated feed amount can be obtained if this feeder is used mating with impact flowmeter produced by our factory. Thus the boiler combustion efficiency can be increased and combustible material in the fly ash can be decreased.
