1. Introduction to Gas Flow Meter

Gas flow meter is an instrument for measuring gas flow rate. Install in the pipeline to record the amount of gas flowing through. Can measure blast furnace gas flow meter, coke oven gas mass flow meter, gas, air, nitrogen, acetylene, phosgene, hydrogen, natural gas, nitrogen, liquefied petroleum gas, hydrogen peroxide, flue gas inspection, methane, butane, chlorine, gas, biogas, carbon dioxide, oxygen, compressed air, argon, toluene, benzene, xylene, hydrogen sulfide, sulfur dioxide, ammonia,

2. What are the specific application scenarios of Venturi flowmeter in power plants?

The core application scenarios of Venturi flowmeter in power plants revolve around precise measurement and energy consumption control of various fluid media, covering the entire process of main and auxiliary systems.

The measurement of the main steam system is mainly used for monitoring the flow of the main steam and reheated steam of the generator set. By accurately measuring the steam flow and calculating the coal consumption and plant power consumption rate in conjunction with pressure and temperature parameters, it is a thermal performance test for power plants The core equipment for AGC load dispatch is the equipment for measuring the amount of waste. Some units with a capacity of over 300MW will install multiple Venturi flow meters in the main steam header and high and low side pipelines to achieve zoning measurement. 2. The measurement of the feedwater system is applied to the measurement of boiler feedwater and condensate flow, and accurate measurement of feedwater flow is a key parameter for balancing the boiler steam water system and regulating the superheated steam temperature

. It can also be used to calculate the thermal efficiency and water replenishment rate of boiler flushing and combustion leakage. Some supercritical units will install Venturi flow meters in the feedwater bypass and condensate fine treatment inlet and outlet to avoid the problem of conventional orifice plates being easily eroded and worn by two-phase flow of steam and water. 3. The measurement of the flue gas system includes monitoring of the exhaust gas, primary air, and secondary air flow at the outlet of the induced draft fan: Wind measurement is used to control the concentration of coal powder transportation and ensure the stability of boiler combustion; -Secondary air metering combined with oxygen analyzer to achieve combustion optimization, reduce NOx emissions and coal consumption; -Some power plants will also install Venturi flow meters in the desulfurization and denitrification inlet flue to accurately measure the flue gas flow rate to match the dosage of chemicals. 4. Auxiliary system measurement covers various auxiliary media measurement in the power plant: - Circulating cooling water flow rate: Monitor the circulating water flow rate of the condenser section shed, calculate the condenser end difference and vacuum degree, and evaluate the heat transfer efficiency; -Compressed air, desalinated water, and fuel flow rates: used for auxiliary energy consumption accounting and material consumption statistics, such as compressed air metering in air compressor stations, which can assist in energy-saving renovations; -Ash water and desulfurization slurry flow rate: used for medium balance control in pneumatic ash removal and wet desulfurization systems to avoid pipeline blockage or excessive dosage of chemicals.
