Industrial boilers are widely used in electric power generation systems to provide the steam that drives large electricity generating turbines. All large industrial boilers are fired by carbon fuel sources such as natural gas, waste gases (co-gen) or coal, which are expensive and result in waste gases that must be treated to prevent air pollution and minimise global warming.
Air preheater (APH) systems recover the lost heat from a boiler’s stack gas in order to enhance the boiler’s efficiency. The heated air from stack gases optimises the boiler’s combustion rate or thermal efficiency, which in turn lowers fuel consumption. Such systems all have one thing in common: They also depend on precise air flow measurement provided by flow meters operating under very high temperature conditions in dirty, hazardous environments.
FCI’s MT100 and ST102A multipoint air/gas flow meters combine state-of-art electronics technology with application-proven precision air flow sensors in a rugged industrial package designed for the most demanding hazardous plant and building operating environments. They provide precision, temperature-compensated direct mass flow measurement of air for highly reliable, repeatable control with low maintenance requirements.
All MT100 and ST102A flow meters have been independently tested and verified to comply with IEC safety directives for EMC and LVD, and carry the CE marking. Optionally available for processes with hazardous, potentially explosive gases and/or dust, they can be ordered with FM/FMc, ATEX or IECEx and other HazEx agency approvals for Division II/Zone 2, or Division 1/Zone 1.
