Swapan Basu, Ajay Kumar Debnath, in Power Plant Instrumentation and Control Handbook, 2015. 8.0 General. Auxiliary steam in a power plant plays a vital role during start-up of the boiler and turbine. In many plants with smaller and medium sized units there may be separate auxiliary steam headers for the boiler and turbine.

Capture of CO2 Emissions from Coal Fired Power Stations

The steam is superheated and supplied to a three stage steam turbine which drives the power generator. The combustion gasses passed through a gas treatment plant where the SOx, NOx, and particles are removed, with the remaining gasses including CO 2, passing out of the flue into the atmosphere. Methods Used to Remove CO2 From Coal Fired Power
