The steam can be used to drive turbines which produce electricity. Alternatively, the boiler can simply be used to heat water or other kinds of fluid. As it recycles some of the energy used, a waste heat boiler, or waste heat recovery boiler, can reduce the fossil fuel consumption and financial running costs of a system.Get Price
What is a Boiler? Boiler Definition Boilers are defined as "Boiler is a closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is super-heated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels, from electricity or nuclear energy.Get Price

2020/6/2 · Steam generators are ideal for on-demand situations. They are smaller and easier to start up compared to steam boilers and, thus, may be used as auxiliary boilers. Generators usually do not have the same maximum capacity as fuel fired boilers, so they are best for applications that require point of use dry steam.Get Price
A steam 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.Get Price
Steam Power Station: Components, Application, and Working Mechanism. Steam Boiler, Thermal Power Plants.
