Effect of Low-NOx Combustion on PM10 Emissions from

Sep 24, 2013 · 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 …

Low-NOx Burners for Industrial Boilers | HPAC Engineering

Jan 09, 2013 · Internal view of a low-NOx burner for an industrial boiler. There are three major types of combustion-related NOx: thermal, fuel bound, and prompt. Thermal. Thermal NOx is created by high flame temperature in the presence of oxygen. The key to limiting thermal NOx is to reduce peak flame temperature and restrict oxygen availability and exposure
