MNT Enviro Tech Continuous Emission Monitoring System uses emission rate calculations to determine compliance. It does this by using a sample probe to extract a small sample of flue gas through a pump into the CEMS system. Facilities using fossil fuels often use a dilution-extractive probe to dilute the sample with clean, dry air. A continuous emission monitoring system (CEMS) is the total equipment necessary for the determination of a gas or particulate matter concentration or emission rate using pollutant analyzer measurements and a conversion equation, graph, or computer program to produce results in units of the applicable emission
