A high-pressure boiler is defined as a boiler in which steam or vapor is generated at a pressure equal to or greater than 15 psig, or a boiler in which water is heated at a temperature of 250°F and a pressure greater than 160 psig, when water is heated for use external to the boiler itself.

These high pressure boilers have pressures above 140 bar and the temperature may be up to 540 – 610°C. High pressure boilers use both natural and forced circulations. Forced circulation is achieved with the help of centrifugal pumps. By using this forced circulation, because of high velocity of water scale formation in the tubes and boiler

2019-10-2 · 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.

A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica, phosphates etc, in relation to working pressure.

1. Boiler pressure drop is higher than that with a subcritical unit. As a result, boiler feed pump power consumption is higher than that of equivalent size drum type boiler. 2. Cost of high-temperature and high-pressure superheater and reheater alloy steel is exorbitant.
