Coal fired power plants Non-invasive flow measurement on .

Non-invasive flow measurement on boiler feed water flows. Coal fired power plants belong to the most common power plants in the world. By burning coal, feed water is heated up into steam for subsequent electricity generation. Measuring the feed water flows to the boiler is of crucial importance for continuous process optimization and to avoid premature failure of the tubes.

Boiler Efficiency - an overview | ScienceDirect Topi

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.

Coal Fired Boiler Emissions Test - E

Entropy tested the exhaust gases from the Unit 1 coal-fired boiler. The furnace burns bituminous coal. Gases from the combustion furnace pass through two electrostatic precipitators (ESPs) to control particulate. Gases exiting the ESPs pass through a flue gas desulfurization unit (FGD), to remove SO2, and are then exhausted through a stack.
