Enhance Emissions Monitoring Systems

Posted on 13th Apr 2017 in Fox Thermal Applications

Emissions Monitoring SystemThe Federal Clean Air Act (FCAA) requires the U.S. EPA to set national ambient air quality standards to ensure public health. State agencies, as well as regional and metropolitan air quality management districts, are responsible for ensuring attainment and maintenance of these standards. These agencies have published rules and regulations regarding NOx and CO emissions from industrial, institutional and commercial boilers, steam generators, and process heaters.

Owners or operators of units subject to these regulations may install a non-resetting totalizing fuel flow meter to measure the total fuel used by each individual unit, as shown in the figure on the right. The regulations specify mass flow measurement of fuel usage and if a volumetric flow meter is installed it must compensate for pressure and temperature using integral gauges. The thermal mass flow meter’s ability to deliver a direct reading of mass flow rate of natural gas and other fuel gases - without temperature and pressure compensation - provides a simple, reliable and costeffective method for tracking and reporting fuel consumption.

The thermal mass flow meter features a variety of analog and digital output signals to easily interface with the emissions management system and an integrated, non-resetting totalizer helps manufacturers meet air quality management equipment requirements. The instrument also offers a very broad measurement range (100 to 1 typical) and is suitable for very low velocity flow measurement.
