Steam and Condensate - A basic overview of a steam

2020-3-9 · A separator is a body in the pipeline which contains a series of plates or baffles which interrupt the path of the steam. The steam hits the plates, and any drops of moisture in the steam collect on them, before draining from the bottom of the separator. Steam passes from the boiler into the steam mains.

US5435138A - Reduction in turbine/boiler thermal

A method of reducing turbine inlet temperature excursions during sudden load demand reductions on a steam turbine, the turbine being coupled to a controllable source of high pressure, high temperature steam, incorporates throttling of steam within the steam source in conjunction with steam throttling at the turbine so as to apportion temperature drops between the source and turbine.

Dynamic Study of the Boiler Outlet to Turbine Inlet

The steam hammer system extends from the outlet of the boiler superheater to the inlet of the steam turbine. The superheated steam exits the boiler at a temperature of 550 degC and a pressure of 260 bar abs and passes through the system at 2400 t/hr and a density of 85 kg/m3. In sections of the system the steam velocity is as high as 50m/s.
