2  · 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

Power Plant -

A variety of EBARA's devices and technologies are used in power plants. Many of EBARA's products and technologies are employed in a number of power plants all over the world, for example, high-pressure boiler feed pumps, large-capacity cooling water pumps, and water treatment equipment for nuclear power plant condensate and cooling water systems.

Boiler Feed Water Pumps & Condensate Pumps

Large industrial condensate pumps may also serve as the feedwater pump. In either case, to force the water into the boiler, the pump must generate sufficient pressure to overcome the steam pressure developed by the boiler. This is usually accomplished through the use of a centrifugal pump.

Design of Boiler Feed Pump Turbines

In other words, the necessary power and speed of the BFPT are determined by the requirements of the pump. In a fully integrated and dynamic system such as this, a large portion of the design requires developing a proper heat balance that will optimize the plant performance. In general, the boiler feed pump turbine uses both steam from the

What is the TDBFP in thermal power plants? Ho

TDBFP stands for TURBINE DRIVEN BOILER FEED PUMP. These kind of pumps are generally designed for large capacities. Boiler feed pump is coupled with a smaller turbine and these turbines are steam driven. Steam is derived from different sources (suc
