Emission Characteristics of Gas-Fired Boilers in Beijing

30/06/2017 · The emissions of NO x, SO 2, and CO for gas-fired boilers in Beijing were 11121 t, 468 t, and 222 t in 2014, respectively. The emissions were spatially allocated into grid cells with a resolution of 1 km × 1 km, and the results indicated that top emitters were in central Beijing. The uncertainties were quantified using a Monte Carlo simulation.

01/07/2018 · Furthermore, according to the revised Emission Standard of Air Pollutants for Boilers in Beijing (BMEPB, 2015), the NOx emission of the new built boilers must be lower than 30 mg/m 3 since April 1, 2017. Simultaneously, for the retrofitted boilers, the emission standard of NOx has dropped from 150 mg/m 3 to 80 mg/m 3.
