摘要
Abstract
The coal pulverizing system of the 300MW coal-fired boiler in a thermal power plant is equipped with the ZGM95G medium speed mill. In view of the problem of too large coal fineness, poor uniformity of pulverized coal and uneven distribution of pulverized coal in the pulverizing system, optimized tests of the pulverizing system were conducted under the single-variable method. The influence of different factors (opening in separator and load pressure of milling system) on the uniformity, the fineness of pulverized coal and the consumption of coal mill is analyzed and compared. Finally, the optimal operating parameter of the o-pening in separator plate is 53' and the load pressure of mill is 9. OMPa. It is showed that the uniform index of pulverized coal can reach 1.16 and satisfy operating requirement under the optimal operating parameters. Moreover, the measure of installing adjustable coal distribution equipment at the back of the separator of coal mill is presented, which improves the uniformity of pulverized coal allocation. Practical operation proves the optimal operation parameters are fit well.关键词
