1. Calculation formula for flue gas flow rate when sampling with pitot tubes in thermal power plants

According to the Bernoulli equation: or Δ P=1/2 ρ V ^ 2, where Δ P is the pressure difference collected by the pitot tube, ρ is the flue gas density, and V is the flue gas flow velocity. The flue gas flow velocity can be calculated using this formula, and the flow velocity multiplied by the cross-sectional area equals the flow rate. Besides, ρ=PM/nRT， The temperature and pressure of the flue gas are related, and the pressure should be basically atmospheric pressure. Temperature has a significant impact, so a temperature sensor is needed to measure the temperature and perform temperature compensation. If necessary, pressure compensation should also be done.

2. How to calculate the flue gas flow rate of a boiler?

1. The first step in determining the boiler flue gas flow rate is to understand the boiler model and the heat generation of the fuel used. Zheng limb 2. For gas boilers, the calculation formula for flue gas flow rate is: flue gas flow rate=flow rate of carbon dioxide and water vapor produced by natural gas combustion+flow r

3. The calculation method for flue gas flow rate of coal-fired boilers is similar to that of gas boilers, and Changqiao needs to consider the products of fuel combustion and the issue of excess air during the combustion process.

3. What are the types of mass flow meters

4. How to convert units in flue gas flow calculation?

1 centimeter=0.01 meter 1 square centimeter=0.0001 square meter high. The smoke flow rate of the boiler is calculated as follows: smoke flow rate x cross-sectional area=243 meters/second x (2820x00001) square meter=68.72 cubic meters per second.

5. How to calculate the smoke flow rate of the boiler? To calculate the flue gas flow rate of a boiler, it is necessary to determine the boiler flue gas volume based on the boiler model and fuel calorific value. If it is a gas boiler, the calculation method for the hood of the boiler is as follows: the flue gas flow rate of the gas boiler=the flow rate of carbon dioxide and steam generated by natural gas combustion+unburned nitrogen+excess air. The calculation method for coal-fired boilers is similar.
