| 摘 要： | 为了既提高锅炉热效率,又确保NOx排放浓度低于650 mg/m3,采用正交试验的方法进行了锅炉的燃烧优化调整.结果表明:上层磨煤机分离器折向门开度、省煤器出口氧量、炉膛与大风箱差压以及OFA风门开度是影响锅炉热效率和NOx排放的4个关键因素.为此确定了一套最优组合方案:上层磨煤机分离器折向门开度为"6",省煤器出口氧量为3.7%,炉膛与大风箱差压为800 Pa,OFA风门开度为25%.按照这一最优组合方案进行了验证试验,结果锅炉热效率达到87.12%,NOx排放浓度为640 mg/m3.

| Abstract: | To improve boiler thermal efficiency and ensure NO_x emission to be lower than 650 mg/m~3,orthogonal experimental method was adopted to carry out the combustion optimizing coordination of boiler.Results show that the deflector opening of the top mill separator,oxygen content at outlet of economizer,pressure difference between furnace and wind box,opening of OFA damper are the four key factors which influence the boiler thermal efficiency and NO_x emission.An optimum combination scheme was determined,of whic... |
