Flow meters optimise waste-to-energy boiler measurement

Louise Smyth

Engineers challenged with designing or operating waste-to-energy incineration plants will find the ST80, ST100 and MT100 Thermal Mass Flow Meters from Fluid Components International (FCI) offer them accuracy, repeatability, ease of installation and low maintenance to enhance plant performance while driving costs down.

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 the ideal solutions to measuring WIP boiler system intake air and back-end flue gasses. In high-temperature, dirty plants with fly ash residue, these thermal flow meters excel with a rugged, no-moving parts design that is resistant to clogging and fouling over a long life.

The 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 is the easiest, most cost-effective solution to install for the larger line sizes common in waste-to-energy incineration plants.
