摘要
针对某电厂一台300 MW前后墙对冲燃烧锅炉,通过上层停运磨通入一次风,改变磨煤机组合、机组负荷、炉膛氧量以及一次风温、一次风量等参数,研究了不同燃烧方式对NOx排放及锅炉经济性的影响,提出了锅炉高效低污染运行的合理方式。
The effect of NOx emission characteristics and boiler economy of different kinds of combustion techniques were studied in a 300MW opposed wall firing boiler by flowing primary air through upper stopped pulverizern and by changing combination of pulverizers,unit load,furnace oxygen,primary air temperature and flow etc.Reasonable boiler operating suggestions of high efficiency and low pollution were then proposed.
