2020-5-15 · Huge quantities of coal burned in coal fired boilers were needed to provide heating and vapor for the production processes in CW, IFP, and LG industries, and large amounts of SO2, NOx, PM, and VOCs are released. To our knowledge, few studies were conducted focus on emissions of coal fired boilers applied in these 3 types of industries.

Effect of Low-NOx Combustion on PM10 Emissions

2019-5-25 · The effect of low-NOx combustion technologies on particulate emissions from coal-fired boilers is much less known. It is investigated in this work by experiments on two 200 MW coal-fired boilers, one with low-NOx combustion and the other with conventional combustion. Collection of particulate matter with an aerodynamic diameter of up to 10 μm (PM10) was carried out at the inlet of
