Historical and Future Emission of Hazardous Air Pollutants ...

The consumption of natural gas in Beijing has increased in the past decade due to energy structure adjustments and air pollution abatement. In this study an integrated emission inventory of hazardous air pollutants (HAPs) emitted from gas-fired combustion in Beijing was developed for the period from 2000 to 2014 using a technology-based approach.

Emission Characteristics of Gas-Fired Boilers based on ...

Gas-fired boilers will become the main stationary sources of NOx in Beijing. However the knowledge of gas-fired boilers in Beijing is limited. In the present study the emission characteristics of NOx SO2 and CO from gas-fired boilers in Beijing were established using category-specific emission factors (EFs) from field measurements. In order to obtain category-specific EFs boilers
