Steam turbines start-ups - imp.gda.

Steam turbines start-ups 171 Prior to switching on the turning gear, oil system is started up. It is always necessary to check whether lube oil pumps has started and whether all bearings are supplied with oil. Control of lube oil pressure and temperature, as well as rotor axial displacement and eccentricity is necessary. The turning gear can be

Boiler (power generation) - Wikiped

A boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi ) but, at pressures above this, it is more usual to speak of a steam generator .

Marine Control Systems: Integrated Systems for All Aspec

In case of the steam propulsion ship the steam from the boiler enters in to the turbine and in turn it is coupled with reduction gear so some of the automatic controls used are. Controlling the speed of the rotation of the turbine in turn it controls the speed of the ship.

Bridge Control Of Steam Turbines With Associated Boile

Author: H O Walker 2010-2-12 · Also, steam is much less dense than liquid water so high velocities are necessary for significant energy transfer. This was recognized by James Watt, who deemed turbines impractical for steam power under the engineering limitations of the time. At the present time, however, steam turbines provide over 80% of electric power.

CHAPTER 4 Steam power plants - WIT Pre

When properly operated and maintained (including proper control of boiler water chemistry), steam turbines are extremely reliable. They require controlled thermal transients as the massive casing heats up slowly and differ-ential expansion of the parts must be minimized. 5. Environment: Emissions associated with a steam turbine are dependent on the

Theory of Steam Turbines - Thermodynamics - Nuclear Pow

In general, a steam turbine is a rotary heat engine that converts thermal energy contained in the steam to mechanical energy or to electrical energy.In its simplest form, a steam turbine consist of a boiler (steam generator), turbine, condenser, feed pump and a variety of auxiliary devices. Unlike with reciprocating engines, for instance, compression, heating and expansion are continuous and
