| 摘 要： | 神华煤容易结焦，单独燃烧可能影响锅炉的安全运行。在一台容量为1025t／h的双炉膛锅炉上，对容易结焦的神华煤和不易结焦的平混煤进行了分层掺烧的数值模拟和性能试验研究，在数值模拟中研究了炉膛内的速度场和温度场的分布，在性能试验中研究了不同掺烧比例下锅炉燃烧特性、排放特性及经济性。研究结果表明：神华煤掺烧量的增多和分层时燃烧位置的提高将导致炉膛结焦倾向增大、Nq浓度下降，但对锅炉热效率影响不明显。并且在不同的分层掺烧方式下，二次风的配风方式有不同的优化值，应通过优化调整试验确定。

| Abstract: | The boiler would suffer severe ash deposition propensity when only Shenhua coal with low ash fusion temperature was supplied.Taking Shenhua coal with low ash fusion temperature and Pinghun coal with high ash fusion temperature as fuel in a 1 025 t/h double-furnace boiler,the numerical simulation and performance tests of layered-combustion were performed.The velocity and temperature distribution of furnace area were analysed by numerical simulation,the characteristic of combustion,emission and economy were s... |
