Steam Boilers: Classification and Selection | Mechanical Engineering
suijitupian65.jpg" />Our engineering team designed a threepass fire tube steam boiler with a capacity of 5000 kg of steam per hour and a operating pressure of 10 bar. The Figure below equations shows a standard three pass fire tube steam boiler system used as a template for our engineering team's design.

suijitupian35.jpg" />Mar 02, 2021 · In most steam boilers, there is a natural circulation of water. #8 Forced Circulation Boilers. In forced circulation boilers, there is a forced circulation of water by a Centrifugal pump, which is driven by some external power. The use of forced circulars is made in high-pressure boilers such as La-Mount boiler, Benson boiler, and Loeffler boiler.

The focus here will be on boilers sized in between these two extremes, which is also where there is the greatest diversity of design. In order of increasing capacity, three boiler types are the fire-tube, water-tube and waterwall boilers.
suijitupian127.jpg" />Up to10%cash back · Circulation refers here to the flow of water, steam, or their mixture around the steam—water circuit in a boiler. In early days of boilers, steam was generated in a large vessel. The vessel was heated from outside, which would create a convective current within the large body of water. This process did not pose any threat to the safety of the

suijitupian99.jpg" />Steam Production From steam tables we can see that the total heat of steam does not vary a great deal as the boiler pressure increase The boiling point (b.p.) increases as the pressure increases Thus the sensible heat increases as the pressure increases, and the latent heat decreases Boiler pressures are expressed in psia, psig, bar, kg/cm2
suijitupian63.jpg" />The boiler is a closed vessel, where the water is stored. Hot gases are formed by burning fuel in the furnace. These gases are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boiler's basic principle is to convert water into steam with heat energy.
