name of low pressure steam boiler

Marine Boilers - Marine Engineering Knowledge Part 1

Boiler is a pressure vessel used on ships in which the water is heated to evaporate and generate the steam and the unit is so arranged that the generated steam accumulated in it. The two main types are water tube and fire tube. It is directly fitted to the boiler shell. The air vent cock is fitted at the top of the steam space of the boiler.

Pressure Steam - an overview | ScienceDirect Topics

Once reheated, the steam is sent to the low-pressure boiler. This improves power generation efficiency by effectively reusing the steam while reducing the percentage losses associated with condensing the steam. This is also used to reduce the liquid water droplets in the steam at the discharge end of the low-pressure turbine.

Boiler Efficiency and Steam Quality: The Challenge of

During periods of low steam demand, or when all the use points require pressure-reducing stations, boilers are often operated at substantially less than design pressure. While operating at lower pressure can, in some boilers, provide slightly higher energy efficiency, low-pressure operation also reduces steam quality.

A 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.
