FCI ST80, ST100 and MT100 Thermal Mass Flow Meters

The ST80, ST100 and MT100 Thermal Mass Flow Meters from Fluid Components International (FCI) are designed to offer accuracy, repeatability, ease of operation, installation and low maintenance to enhance plant performance while driving costs down in waste-to-energy incineration plants.

Waste incineration plants (WIP) applying waste-to-energy (WTE) technologies provide an economical and decreased waste footprint alternative to conventional organic waste disposal. WIPs convert their waste streams into electrical power by burning the waste to heat steam boilers, which in turn drive turbine electric power generators.

The WIP combustion process uses forced draft primary air and grate air, and in some systems secondary air, that all must be measured for efficient mixing and boiler control. All WIP systems require the measurement of the air mass flow rate to control the boiler properly and treat end-of-process hot flue gases.

FCI’s ST80, ST100 and MT100 Series Thermal Mass Flow Meters are used for measuring WIP boiler system intake air and back-end flue gases. The meters are suitable for use in high-temperature, dirty plants with fly ash residue, due to their rugged, no-moving parts design that is resistant to clogging and fouling over a long life.

FCI’s compact thermal dispersion mass flow meters are direct mass flow instruments that do not require the addition of costly temperature or pressure sensors, or their added wire-runs and pipe penetrations. Their insertion-style configuration provides an easy, cost-effective solution to install for the larger line sizes common in waste-to-energy incineration plants.

Typical WIP requirements that FCI meters meet include pipe diameters that range in diameter or square/rectangle sizes from 200 to 2500 mm, temperatures of 0 to 260°C and pressures of 0.05 bar [g].
