Mercury emissions from coal-fired power stations: The

About 30% of the electricity produced in the Netherlands is generated by coal, all of which is imported. At the same time, the co-combustion of biomass is becoming increasingly important. For the last 25 years, the fate of the elements/trace elements in general and of mercury in particular has been studied in great detail. It appears that on average 50% of the mercury is removed in the ESP

EMISSIONS OF SULFUR TRIOXIDE FROM COAL-FIRED …

Emissions of sulfur trioxide (SO3) are a key component of plume opacity and acid deposition. Consequently, these emissions need to be low enough not to cause opacity violations and acid deposition. Generally, a small fraction of sulfur in coal is converted to SO3 in coal-fired combustion devices such as electric utility boilers. The emissions Of SO3 from such a boiler depend on coal sulfur

Dynamic inferential NOx emission prediction model …

The selective catalytic reduction (SCR) decomposition of nitrogen oxide (de-NO x) process in coal-fired power plants not only displays nonlinearity, large inertia and time variation but also a lag in NO x analysis; hence, it is difficult to obtain an accurate model that can be used to control NH 3 injection during changes in the operating state. In this work, a novel dynamic inferential model

Boiler Efficiency - an overview ScienceDirect Topics

The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.
