摘要
提出了一种煤量平均热值计算方法,为电厂运行人员配煤掺烧时提供了可量化的参考;同时提出一种应对煤质劣化情况下送风自动的投入解决方案和自清灰式风量测量装置,进一步改善送风系统自动调节效果,对同类型机组送风系统的自动调节优化有一定参考意义.
Abstract
A method of calculating the average calorific value of coal quantity is proposed,which provides a quantifiable reference for the power plant operators when coal blending at the same time,a solution of inputting the air supply automation in case of deterioration of coal quality and a self-cleaning air volume measuring device are proposed to further improve the effect of the automatic adjustment of the air supply system,which is of some reference significance for the optimisation of the automatic adjustment of the air supply system of the same type of units.
