Boiler (power generation) - WikipediaDeze pagina vertalen

Haycock and wagon top boilers. For the first Newcomen engine of 1712, the boiler was little more than large brewer's kettle installed beneath the power cylinder. Because the engine's power was derived from the vacuum produced by condensation of the steam, the requirement was for large volumes of steam at very low pressure hardly more than 1 psi (6.9 kPa) The whole boiler was set into brickwork ...

Maintenance and Overhaul of Steam Turbines WGP42 05 · PDF-bestand

Steam turbines are fundamentally the same regardless of whether they drive a simple 500 shaft horsepower (SHP) fan or drive a 1,000 MW generator. In all cases, steam is expanded through rows of stationary and rotating blading which convert the energy in the steam into mechanical energy.

Stabilizing a 46 MW -Stage Utility Steam .

A 46 MW 5,500 rpm stage single casing utility steam turbine experienced strong subsynchronous rotordynamic vibration of the first rotor mode; preventing full load operation of the unit. The root cause of the vibration stemmed from steam whirl forces generated at secondary sealing locations in combination with flexible rotor-bearing system. Several attempts were made to eliminate the ...

Steam Turbine Bypass Valve Vibration - Control

08.08.2014 · We have a large steam turbine which drives a 4 pole generator (Approx 750 MW of power). The turbine has 4 steam control valves that drive steam into the machine. If, for whatever reason, the plant experiences a shutdown, those valves close and another 4 valves open (the bypass valves) which drive the steam to a different circuit through the condenser. Our problem right now is that we are ...
