Method for Identifying Areas of Sulfidation on Water-Wall Tubes in Coal-Fired Boilers …
2015/8/20 · In Japan, pulverized-coal-fired thermal power plant boilers are operated with a high two-stage combustion ratio to reduce NOx emissions. This combustion ratio forms a strongly reducing atmosphere containing H2S at the burner zone. Water-wall tube materials, such as low-alloy steel, sulfidize severely in such an atmosphere. In the past few years, wastage of the …

Pulverized coal-fired boiler - Wikipedia
Pulverized coal-fired boiler. A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox. The basic idea of a firing system using pulverised fuel is to

Mercury Stable Isotope Fractionation During Coal Combustion in Coal-Fired Boilers: Reconciling Atmospheric Hg Isotope Observations …
2019/1/2 · During coal combustion in coal-fired boilers at 1200–1500 C, most of Hg in the feed coals is volatilized, leaving trace levels of Hg in bottom ash (< 1%, Table S1). Because lighter Hg isotopes have higher volatilization velocities, the residual Hg in the bottom ash
Read MoreBoiler Combustion | CleanBoiler.org
As a safety factor to assure complete combustion, boilers are fired with excess air. One of the factors influencing NOx formation in a boiler is the excess air levels. High excess air levels (>45%) may result in increased NOx formation because the excess nitrogen and oxygen in the combustion air entering the flame will combine to form thermal NOx.
