Exploration and Practice of Optimizing Industrial Coal Powder Boiler Pulverization System
Taking Shaanxi Yanchang Coal Yulin Energy and Chemical Co.,Ltd.as an example,in view of the problems such as the substandard pulverized coal fineness of the boiler pulverizing system,the large deviation of the air speed of the primary air duct at the outlet of the pulverizer,and the poor combustion effect of pulverized coal entering the furnace,the pulverizer loading force char-acteristics,separator baffle opening characteristics,pulverizer output characteristics and other adjustment tests were carried out for the pulverizer system,the pulverized coal fineness at the outlet of the pulverizer was adjusted to a reasonable level according to the characteristics of the actual coal burning,and the reasonable range of recommended parameters for the optimal operation of the pulverizer was provided.At the same time,in response to various problems discovered during the adjustment and testing process of the boiler powder making system,basic measures for subsequent equipment operation and maintenance,as well as technical transformation routes,have been proposed.This method is of great significance for improving the overall equipment status of the thermal power workshop by on-site adjustment and testing,identifying existing problems and solving them one by one.
