Boilers are generally used to provide a source of steam or hot water for facility heating and process needs. In steam and condensate systems ('''Figure 5'''), heat is added to water in a boiler causing the water to boil and form steam. The steam is piped to points requiring heat, and as the heat is transferred from the steam to the building area or process requiring heat, the steam condenses to form condensate.
Purpose of Boiler water treatment. 1) To prevent the scale formation in the boiler and feed system 2) To prevent corrosion in boiler and feed system. 3) To control the sludge formation and prevention of carry over with the steam. 4) To maintain the boiler water in alkaline condition and free from dissolved gases.
Jul 30, 2019 · Boiler Economiser and Waste Heat Recovery Concept. Boilers are generally designed to produce steam from water. Water is converted to steam by transferring both sensible and latent heat. Sensible heat is the amount of heat required to increase the temperature of water at constant pressure without changing its liquid state,
Combustion Training. A boiler is an enclosed vessel in which water is heated and circulated, either as hot water, steam, or superheated steam for the purpose of heating, powering, and/or producing electricity. The furnace of the boiler is where the fuel and air are introduced to combust; fuel/ air mixtures are normally introduced into
Aug 01, 2000 · Boiler bypass lines must be installed with care to prevent serious difficulties from developing in the system. A circulator on the boiler side of the bypass raises the return water temperature. A circulator on the system side of the bypass lowers the supply water temperature. Boiler manufacturers emphasize bypass lines today—and with good reason.
The main purpose of boilers is to produce a good reservoir of heat energy through steam under pressure that can be readily converted into work inside heat Engines. Other uses include using the steam reservoir for heating and drying purposes at hom
The main purpose of a boiler feed pump turbine is to pump feedwater into a steam boiler. The feedwater can be either freshly supplied or the returned condensate product from the steam produced by the boiler. The boiler feed pumps normally work with high pressure, which sucks the condensate return and it is mainly a centrifugal type pump.
