Boiler Pressure - an overview | ScienceDirect Topics

Feb 15, 2019 · The system pressure must be at least 25 psig above the saturation pressure of the high-temperature water's maximum temperature to prevent pump cavitation and flashing of superheated water to steam. Section 1004 of the International Mechanical Code (IMC) describes the minimum allowable requirements for boilers.

A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power.. In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above the critical pressure – 22 megapascals (3,200 psi).Therefore, liquid water immediately becomes indistinguishable from steam.

Ultra-Supercritical Pressure CFB Boiler Conceptual Design

Jun 30, 2006 · The advantages of supercritical (SC) and ultra supercritical (USC) pressure steam conditions have been demonstrated in the high gas temperature, high heat flux environment of large pulverized coal-fired (PC) boilers. Interest in circulating fluidized bed (CFB) combustion, as an alternative to PC combustion, has been steadily increasing.
