Study on the Concentration Measurement of the Pollution Gases from Coal-Fired Power Station

摘要

CO2 is a main kind of pollution gases discharged from coal-fired power station. The relationship between gas concentration and pressure, temperature is deduced base on the law of Beer-Lambert and the theory of gas line-shape. The tunable diode laser spectral technology is used to analyze the changing regularity of the peak, half-peak width of the absorption curve with pressure and temperature.
