What are the main types of flow meters used for measuring primary and secondary air in power plants?
Thread Content
As the title suggests, the temperature of primary and secondary air is usually around 300 degrees. 1. So what type of flow meters are generally used in power plants to measure air flow? 2. Additionally, for the steam used for soot blowing, the pressure is generally around 1 MPa and the temperature is about 300 degrees; what type of flow meter is suitable for measuring flow in such pipelines?
I. For the measurement of primary and secondary air flow rates, we generally use heat mass flow meters
Multi-throat flow meters are suitable for measuring the flow rate in the primary and secondary air ducts of power plants. http://bbs.hcbbs.com/thread-577811-1-1.html There are pictures and explanations here. You can take a look.
