There are three applications for thermal mass flow meters that support the use of industrial furnaces and smelters in metal production; including air/fuel, flue and stack gas monitoring, and argon, nitrogen, and oxygen measurement.
- Furnaces – air and fuel, flue and stack gas monitoring
- Argon and nitrogen for tank blanketing and stirring
- Air/fuel ratio control on the furnace
Air / Fuel / Flue / Stack Gas Monitoring
Furnaces are used in a wide variety of industries and facilities including metals. When using an industrial furnace in a manufacturing process, air/fuel monitoring, flue, and stack gas monitoring are often needed and satisfied with thermal mass flow meters.
Measure Gas Flows
Different gases are used in the production of metal, including natural gas, oxygen, chlorine, argon, and nitrogen. A minimum gas flow is needed in these processes often, and thermal mass flow meters often work well in these applications. Additionally, lower gas usage can affect product quality, and thermal mass flow meters measure gas flows to ensure the optimum amount of utilized gas.
Argon & Nitrogen for Blanketing and Stirring
Argon and Nitrogen gas are used as a blanketing gas in many production applications of various metals. Thermal mass flow meters measure the flow rate of gases to the different blanketing application to ensure adequate coverage.
Argon and Nitrogen are also used for bottom stirring in metal products, and pressure monitoring of these gases is needed to obtain the proper mix for optimum steel quality.
Air/Fuel Ratio Control on Furnace
Stoichiometric ratio control on furnaces in the smelting process of metals is critical to product quality. Sage meters in conjunction with oxygen monitoring provide optimal control in furnace air/fuel ratio control loops.
