锅炉二次风流量及磨煤机一次风流量的准确测量

Accurate Measurement of Boiler Secondary Air Flow and Mill Primary Air Flow

火力发电厂锅炉二次风流量和磨煤机一次风量自动控制系统稳定可靠的投入是机组安全稳定运行的重要保证,也是保证机组协调系统投入品质的基础。本文介绍采用防堵型阵列风量测量装置对锅炉二次风流量进行测量,采用FCI公司的MT86HT型热扩散式气体流量计对磨煤机热风流量和冷风流量分别进行测量,准确可靠测得锅炉二次风流量和磨煤机一次风量。

The stable and reliable input of boiler secondary air flow auto-control system and the mill primary air flow auto-control system is an important guarantee for thermal power plant. It is also the basis of the quality of CCS. This article describes the measurement device for boiler secondary air flow which is using blockades array air flow measuring device. And the measurement device for mill primary air flow which is using the gas flowmeter based on thermal diffusion of MT86HT type of American FCI. This accurate and reliable measures the boiler secondary air flow and the mill primary air flow.
