Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank.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
Feb 19, 2020 · Boiler feedwater (BFW) pumps are an important part of many different industrial plants and facilities. These pumps are a special class of high-pressure centrifugal pumps used in many different models and sizes in many different plants, units, and production facilities. However, BFW pumps are not well-known by many engineers and operators.Get Price
As obstruction can cause premature wear of the pumps, the BOLLFILTER Simplex Type 1.88.2 placed upstream of the boiler feed water pump removes impurities from the boiler feed water and as such protect the pump. After being used in the turbine, the steam is cooled down and condensed before being returned to the boiler from the hot well. As a Get Price
