IRON AND STEEL PLANT GAS FLOW MEASUREMENT
Thermal mass flow meters are used in steel production plants for combustion control, compressed air and nitrogen flow control. In addition, the thermal mass flow meter is ideal for monitoring natural gas, nitrogen and argon to improve product quality and protection.
Steel Production and Combustion Control
Steel processing uses large amounts of energy for its processing. One of the most important ways to reduce energy consumption is to optimize the combustion control of boilers and furnaces. Optimal air-fuel ratios are achieved when monitoring the burners’ air and fuel ratios. This practice significantly reduces natural gas (or propane) energy costs and improves process efficiency.
Thermal mass flow meters are ideal instruments for this application. They require no separate temperature or pressure compensation, have no moving parts, are highly accurate and repeatable, and cause very little pressure drop compared to other measurement methods. In addition, thermal mass meters have a 100:1 turn down ratio, which is critical for optimizing combustion control.
Compressed Air or Nitrogen Flow Control
The steelmaking plant has many applications for monitoring compressed air flow. In addition, air contains a significant amount of oxygen, which reacts with steel at high temperatures and forms oxides, so nitrogen is used instead of air. In both cases, thermal mass flow meters are ideal for measuring these gases.
Control of Nitrogen and Argon Gases
Monitoring the nitrogen and argon flow rate for bottom mixing of molten steel helps to remove bubbles and other impurities. The proper mixture of nitrogen and argon directly affects the quality of the steel. Sage Prime and Sage Paramount Thermal Mass Flowmeters are the optimum solution for this critical application.
