Steam turbines and gearing arrangement - Energy conversion

Steam turbines and gearing - operating principle 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 it after giving off the most of it. The high pressure steam from the boiler expands in nozzles to crate a high velocity steam jet.

Life on a Fletcher Class Destroyer in the 1950's | Naval

Jul 31, 2013 · Astern elements were provided in the LP turbine. To go astern you had to shut off steam to the ahead turbines before you could admit steam to the astern turbine. Control was manual; by hand wheels mounted on a large gage board adjacent to the engine in response to engine order telegraph signals from the bridge.

Water Handbook - Steam Purity | SUEZ

Precise system control is required for the operation of modern superheated steam turbines. Solids in the steam leaving a boiler can deposit in the superheater and turbines, causing costly damage. For this reason, close control of steam purity is critical. Steam purity refers to the amount of solid, liquid, or vaporous contamination in the steam.

Boiler Follow Mode and Turbine Follow Mode and - control

Apr 29, 2017 · Turbine Follow Mode: Turbine control valves maintain a set pressure while the boiler fires to maintain load. Drawback here is a slower generation response. There are variations with this scheme, in that the turbine control valves can be fully opened at higher loads to minimize the energy penalty associated with the DP loss across them.
