GAS TECHNOLOGY: Boiler NOx Emissions - Plant Engineering

In many areas, industrial boiler operators face stricter regulation of NOx emissions, even with the use of clean natural gas. In some areas, operators are required to meet what are called "Ultra-Low NOx" (ULN) requirements, typically less than 10-12 ppm. It is widely believed that the ULN requirements will be broadened to more areas. In []

The choice of pitch and wall thickness for a given SCR installation is determined mainly by the dust content of the flue gas. For low-dust applications, channel sizes of 2-4 mm with e.g. 0.4 mm wall thickness are selected.

Effect of Low-NOx Combustion on PM10 Emissions from

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 the Cited by: 5Publish Year: 2013Author: Dunxi Yu, Chang Wen, Minghou Xu[PDF]1.2 Anthracite Coal Combustion - US EPAhttps:// has been combusted primarily in fluidized bed combustion (FBC) boilers because of its high ash content and low heating value.
