Overview:
Industries relying on combustion processes—such as power plants, steel foundries, and chemical plants—face a common challenge: accurately measuring flue gas flow in moist environments. Flue gas, often laden with moisture, particulates, and sticky contaminants, creates harsh conditions that can compromise the performance and lifespan of traditional flow measurement devices.
Thermal Mass Flow Meters have emerged as a reliable solution, offering unparalleled accuracy, durability, and efficiency in these demanding applications. In this blog, we’ll explore how Leomi Instruments’ Thermal Mass Flow Meters overcome the unique challenges posed by moisture in flue gas environments, ensuring precise and reliable measurements.
The Challenges of Moist Flue Gas Measurement:
Flue gas from combustion processes typically contains a complex mixture of nitrogen, carbon dioxide, carbon monoxide, water vapor, and particulate matter. Measuring flow under such conditions presents several challenges:
-
- Moisture Interference: Moisture content affects the accuracy of many conventional flow meters, leading to unreliable readings and frequent calibration issues.
- Particulate Build-Up: Sticky particulates and dirt in the gas can clog sensors, degrade performance, and increase maintenance requirements.
- High Temperatures and Variable Flow Rates: Flue gas systems often operate under extreme temperature conditions, with highly variable flow rates that many flow meters struggle to accommodate.
- Pressure Drops: Traditional flow meters like orifice plates and pitot tubes introduce significant pressure drops, limiting their suitability for low-flow or fluctuating conditions.
Thermal Mass Flow Meters: A Game-Changer for Flue Gas Applications:
Thermal Mass Flow Meters are designed to address these challenges head-on. Unlike traditional technologies, these flow meters measure mass flow directly by sensing the heat carried away by the gas stream, making them inherently resistant to moisture and particulates.
