电站锅炉钢球磨制粉、燃烧系统现状和发展

Present situation and development of ball mill pulverized coal preparation system and com bustion system of utility boilers

为使大容量燃煤锅炉很好地适应燃料品种及成份变化,分析电站常见的钢球磨制粉、燃烧系统的运行特性,建议采用一种宽幅调节特性的制粉、燃烧系统,以提高锅炉机组运行可靠性和经济性,有效控制NOx等污染物排放。

In order to adapt the large utility boilers to the change of coal grade and composition,the article analyzes the operation performance of ball mill pulverized coal preparation and combustion systems ,suggests to adopt a new approach so called pulverized coal preparation and combustion systems with wide-range control characteristics in an attempt to improve the reliability and economics of boiler unit and effectively control NOx etc.pollutants emissions.
