在锅炉直吹式制粉系统中,由于各分支管道长度、结构、布置上有差别,使得各管道的风粉分配很不均匀,因而直接影响到锅炉的安全经济运行。在直吹式制粉系统中,装置节流元件,来均衡各管道阻力,解决风粉分配不均匀问题,已取得了一定的效果。如淮北电厂~#1炉采用弧型节流元件,解决了送粉管道的堵粉问题。在一些新机组上也采取了这种措施。但
In the boiler direct blowing pulverizing system, due to the differences in length, structure and layout of the branch pipes, the distribution of the air powder in each pipeline is very uneven, which directly affects the safe and economical operation of the boiler. In the direct blowing pulverizing system, the device throttles the components to balance the resistance of the pipes and solves the problem of the uneven distribution of the powder, which has achieved certain effects. Such as ~ # 1 furnace in Huaibei Power Plant using arc throttle components, to solve the powder feeding pipe plugging problems. In some new units have also taken such measures. but
