Steam drum—the top drum of a boiler where all of the generated steam is collected before entering the distribution system, p. 293. Steam trap—a device used to remove condensate or liquid from steam systems, p. 294. Superheated steam—steam that has been heated to a very high temperature so

2012-5-10 · A simple steam turbine CHP system needs a boiler and steam generator to raise the steam to drive the unit. The fuel can be any fossil fuel as well as biomass fuels. For highest electrical conversion efficiency, the steam will be condensed at the exit of the steam turbine, creating the largest pressure drop possible across the turbine blades.

Swapan Basu, Ajay Kumar Debnath, in Power Plant Instrumentation and Control Handbook, 2015. 3.6.6.1 Requirements of Condensate Polishing Unit. Boiler pressure is the key factor for determining the requirement of a CPU system (see Figure II/3.6.6-1).For the steam generator plant with low steam pressure (below 40 kg/cm 2), the requirement of a condensate polishing unit is usually avoided.

2018-10-17 · The steam turbine is a device for obtaining mechanical work from the energy stored in steam. Steam enters the turbine with a high energy content and leaves after giving up most of it. The high-pressure steam from the boiler is expanded in nozzles to create a high-velocity jet of steam…

2020-5-5 · Boiler master, for main steam header pressure control With all the above control loops in auto mode, the boiler is finally placed into auto mode. The controls automatically respond (firing rate control as well as air flow controls with O2 trim) to maintain the desired steam pressure.
