In large-scale p. f. fired boilers, large deviations of flue gas temperature and velocity often exist at furnace exit and at horizontal flue pass along furnace width, making overheat, ash accumulation and slag boding of convection heating surface. Tests on a 2000MW utility boiler affirm:flue gas temperature deviation on convection heating surface arive from velocity deviation, which arise from residual rotation at furnace exit.

In large-scale p. f. fired boilers, large deviations of flue gas temperature and velocity often exist at furnace exit and at horizontal flue pass along furnace width, making overheat, ash accumulation and slag boding of convection heating surface. Tests on a 2000MW utility boiler affirm:flue gas temperature deviation on convection heating surface arive from velocity deviation, which arise from residual rotation at furnace exit. Residual rotation at furnace exit can be eliminated by decreasing revolving intensity of airflow in furnace. Through injecting overheated air anti-tangentially into furnace, results show: residual ratation at furnace exit becomes small, an uniform velocity distribution along furnace width can be expected on horizontal flue pass, and aerodynamics in furnace is less affected.

某电厂200MW机组的冷、热态试验结果表明:高温对流受热面的烟气温度偏差是由速度偏差引起的,而水平烟道中的烟速不均是由于炉膛出口的残余扭转引起的,消除和削弱炉膛出口的残余扭转就应使炉内气流的旋转强度减弱。因此,在冷态模化试验台上进行了三次风反切的试验研究,结果发现:通过三次风反切,能够削弱炉膛出口的扭转残余,在水平烟道中形成一个较为均匀的速度分布,且对炉内空气动力结构无明显影响,这对机组的安全经济运行起促进作用。

Finally, the means to decrease the deviation are introduced.

为了防止大型电站锅炉炉内结渣,减轻高温对流受热面处烟气温度偏差,本文提出了二次风燃烧器喷口反切布置的同心圆燃烧方式。通过对炉内气相流动的冷模试验研究和数值模拟,单颗粒炉内运动的数值模拟和颗粒群在炉内运动的冷态试验研究结果表明:合理的二次风反切可在炉内形成“风包粉”燃烧方式,且使水平烟道内高温对流受热面处的气流速度和颗粒得到均匀分布,这对防止炉内结渣、减轻高温对流受热面热偏差起促进作用。
