Answer / Gaurav Kumar Sinha

To measure the volumetric flow of gas in a waste heat recovery boiler, you can use various flowmeters such as orifice plates, venturi tubes, or rotameters. However, for high-temperature applications, a vane-type or turbine flowmeter might be more suitable due to their ability to handle higher temperatures and pressures. In addition, it is important to consider the gas composition and any potential corrosive effects on the measuring instrument.
