For coal-fired boilers: coal rate of 8 ~ 20%; clear coking coal-fired system 50 ~ 95%; to reduce sulfur emissions 20 ~ 30%; to reduce harmful gas emissions 50 to 95 percent; firepower improve about 20%; lower value of about 14% of spontaneous combustion, and life brought about by the extension of the boiler to reduce the repair cycle of the furnace, flue, heating surface, such as equipment maintenance Qing Jiao role in enhancing the stability of combustion, reducing harmful gas emissions and other benefits.

对于燃煤锅炉：节煤率为8～20％；清除燃煤系统结焦50～95％；降低硫排放20～30％；降低有害气体排放50～95％；火力提高20％左右；降低自燃值14％左右，并带来延长锅炉使用寿命，减少维修周期，对炉膛、烟道、受热面等设备具有清焦保养作用，提高燃烧的稳定性，减少有害气体的排放等效益。

Based on it,three dimensional numerical simulation of Natural Gas Rebuming is carried out.With the typical tangentially fired boilers in China as research object,it is set up that the pulverized coal combustion models and the NOx models.Through CFD method,the combustion process is simulated.All of these will promote the engineering applications of fuel reburning technology.

在此基础上，对燃煤锅炉的天然气再燃过程进行了系统的三维数值模拟，以我国典型的四角切圆煤粉锅炉为研究对象，建立了煤粉扩散燃烧和污染物NOx生成-还原模型，采用计算流体力学方法，模拟其燃烧过程，促进了再燃低NOx技术应用的推广。

Boiler tubes for all types of fuel such as coal, gas, oil, black liquor and biomass.
