2019-5-4 · 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.
2016-7-14 · STEAM TURBINE-GENERATOR SHAFT GROUNDING PRINCIPLES Historically, the problems and solutions to electrostatic and magnetically induced voltages on the steam turbine-generator shafts of the test utility's steam electric stations have been a continuous one.

ZOZEN boiler as a pioneer in China's boiler industry,can provide many professional types of industrial boiler ,such as,gas&oil boiler, coal-fired boiler, biomass boiler, thermal fluid heater and other series of more than 400 varieties of specifications.
2019-5-15 · A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Sir Charles Parsons in 1884.[1][2] Because the turbine generates rotary motion, it is particularly suited to be used to drive an electrical generator—about 85%
