Steam Turbine Bypass Valves

The bypass function requires valves to quickly and accurately change load on the turbine during startup, emergency, or clean-up situations. Turbines and boiler tubes are among the highest cost and critical assets within a power generation facility, and for this reason, they must be adequately protected from having to operate outside their normal process temperature and pressure conditions.

PDF Catalog of CHP Technologies, Section 4. Technology

Steam turbines differ from reciprocating engines, internal combustion engines, and gas turbines in that the fuel is burned in a piece of equipment, the boiler, which is separate from the power generation equipment. The energy is transferred from the boiler to the steam turbine generator by an intermediate medium, typically steam under pressure.

STEAM POWER CYCLE - MassEngineers.com

STEAM POWER CYCLE . Power plants generate electrical power by using fuels like coal, oil or natural gas. A simple power plant consists of a boiler, turbine, condenser and a pump. Fuel, burned in the boiler and superheater, heats the water to generate steam. The steam is then heated to a superheated state in the superheater.

Steam systems | Steam Turbo - Micro steam turbines, small

Most steam systems raise high-pressure steam in the boiler, then reduce the pressure before the steam is actually used. That's because high-pressure steam is more energy-dense, so it's more efficient to move from the boiler to the point of use than piping low pressure steam over long distances.
