In a coal fired power plant electrostatic precipitators are installed to control emission of

Options

(a) NO2
(b) SPM
(c) CO
(d) SO2

Correct Answer:

SPM

Explanation:

In recent years, the increases in toxic substances of NOx and/or SPM(Suspended Particulate Matter) from vehicles come to be serious problem.About the correlation between the traffic volume in our model and the real volume, we obtained the correlation coefficient of 0.74. Simultaneously, we got the result that the concentration of NOx was approximately 70 to 230 ppm. That of SPM was approximately 40 to 100 μg/m³.
