Steam Turbine - Department of Energy
with natural gas and coal. A 500 kW steam turbine utiliz-ing a natural gas fired boiler will have estimated NOx emissions in the range of 26-81 ppm (at 3% oxygen). A larger 15,000 kW CHP steam turbine integrated with a natural gas boiler will have estimated NOx emis-sions in the range of 81-226 ppm (at 3% oxygen). This 15,000 kW steam turbine

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.

Feedwater Deaerators | Oxymiser | Hurst Boiler
This steam is induced through a stainless steel spray valve assembly which causes the high velocity steam to break the water down to a fine mist through a violent scrubbing action. The deaerated water spills over to the tanks storage compartment for use by the boiler, and the gases are vented to …
