What are the various methods for measuring flue gas flow rate?
Thread Content
Let’s discuss the various methods for measuring flue gas flow rates. It is generally assumed that the flue gas in question is the gas exiting the boiler, containing some ash. What types of flow meters are used? Standard literature recommends the use of Venturi meters and vortex flow meters; however, in practice, V-cone meters seem to be more practical. How can flue gas flow rates be measured?
Vortex flow meters can be used when high precision is not required, while thermal flow meters are suitable for applications where high precision and low moisture content are necessary
Well, I see that the vortex street method is also recommended by many people. Could you explain in detail the specific measurement methods, such as the steps involved?
