Measurement and control of pulverized coal feed quantity for pulverized coal boiler of power plant

Abstract

Abstract: Abstract:The factors influencing on pulverized coal flow in pulverized coal conveying pipeline were analyzed. The problems existed in combustion process of pulverzed coal boiler in power plant were expounded. The principle and the defects of the microwave solid flowmeter were introduced. A newtype microwave solid flowmeter was adopted. The defects of traditional microwave flowmeter were overcome. The realtime noncontact measurement of the pulverized coal density was realized, and the pulverized coal feed quantity of the pulverized coal boiler was controlled effectively.

Key words: Keywords:microwave solid flowmeter, pulverized coal boiler, flow, measurement
