摘要

电站锅炉运行中一次风煤粉浓度的测量十分困难

尤其是乏气送粉锅炉一次风煤粉浓度的测量目前还没有可行的方法。在试验台上进行乏气送粉煤粉浓度测量的试验研究

得出温度不变且气流速度一定时

煤粉与空气混合前后的静压差与煤粉浓度线性相关。试验结果为乏气送粉煤粉浓度的测量提供了新的思路和方法

Abstract

In operational parameters of the pulverized coal burner

the measurement of pulverized coal concentration in primary air is very difficult

having no effective monitoring method. Especially for measuring pulverized coal concentration in primary air for boilers using exhaust gas to convey the pulverized coal

there is no feasible method up to now. Hence

it has certain infuence upon thorough study on operational behavior of burners

on operation optimization of them

on equipment retrofitting and improving combustion performance etc.. Througth establishment of test stand for measuring concentration of pulverized coal

the experimental study on measuring concentration of pulverized coal using exhaust gas to convey has been carried out

obtaining linear correlation between static pressure difference before and after mixing pulverized coal with primary air under conditions of constant temperature and fixed gas flow velocity

and the concentration of pulverized coal

providing new thinking and method for measuring concentration of pulverized coal using exhaust gas to convey.
