The ST80, ST100 and
MT100 thermal mass flow meters from Fluid Components International (FCI) offer
accuracy, repeatability, ease of operation, installation and low maintenance to
enhance plant performance while driving costs down in in waste-to-energy
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, all of which 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 ideal for measuring WIP boiler
system intake air and back-end flue gases. 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.
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.
No matter the FCI
flow meter model series, these thermal mass flow meters support WIP needs. Typical
WIP requirements that FCI meters meet include pipe diameters that range in
diameter or square/rectangle sizes from 200mm to 2500mm, temperatures of 0¡C to
260¡C and pressures of 0,05 bar [g].
Model ST80 Series
The ST80 air/gas
flow meter features a unique dual technology flow element that combines the
advantages of fast response with high accuracy over a broad flow range. The
ST80 is suitable for use at temperatures up to 454¡C. It operates over a flow
range of 0.07 to 305 NMPS. Flow accuracy is ±1.0% reading, ±0.5% of full scale,
with repeatability of ±0.5% reading.
Model ST100 Series
The ST100 is a
thermal dispersion technology flow meter that combines the industry’s most
feature- and function-rich electronics with advanced flow sensors. The result
is a truly advanced solution for industrial processes and plant applications.
In addition to the
single-point Model ST100, the ST102A dual-point averaging meter is an
economical solution to achieve higher accuracy in larger pipe or duct sizes
with non-repeatable or flat profile flow conditions. The ST100 Series meters
operate over a flow range of 0.07 to 305 NMPS with accuracy of ±0.75% reading,
±0.5% full scale, with repeatability of ±0.5% reading.
Model MT100 Series
The MT100 is an
insertion type, multipoint (3-8 points) thermal flow meter specifically
designed for difficult to measure big diameter pipes and large ducts, such as
in industrial power generation combustion air intakes, stacks and flues. It
operates at temperatures up to 454¡C over a flow range of 0.07 to 305 NMPS. Up
to eight flow sensors can be placed in the flow stream, either as individual
tap points or as an array across a single mast. All sensors are averaged to
produce accurate, repeatable flow measurement of ±1.75% of reading, ±0.5% of
full scale with repeatability of ±0.5% reading.
All of these
instruments are compatible with a client’s control system, featuring multiple
4-20mA, NAMUR NE43 compliant analogue outputs, HART, Modbus, Foundation
Fieldbus, and/or Profibus-PA and -DP. They are all available for powering via
24Vdc or 115/230Vac.
