摘要
针对锅炉飞灰可燃物含量对锅炉效率及机组的整体运行经济指标的直接影响,本文从运行煤质、煤种、煤粉细度、锅炉负荷、过量空气系数、配风方式与炉内空气动力场、热风温度、燃烧工况等方面,对飞灰可燃物进行含量影响因素的理论分析,并结合设备实际情况找到了可能造成飞灰可燃物含量升高的各种因素。同时,根据找出的问题原因,提出降低飞灰可燃物的重点应对措施。
The content of combustibles in the fly ash of the boiler has a direct impact on the efficiency of the boiler and economic indicators of the overall operation of the unit. This paper introduces the theoretical analysis of the influencing factors of the content in the aspects of the quality of coal,the type of coal,the fineness of the pulverized coal,the load of the boiler,the excess air coefficient,the way of air distribution,the aerodynamic field within the boiler,the temperature of the hot wind,the combustion condition... etc. In addition,it introduces possible factors causing the content to rise base on the actual situation of the equipment. Finally,it puts forward relevant solutions to reducing the combustibles.
