SUPERCRITICAL. BOILER. Presented by : Deepak Kumar Sharma DEPUTY DIRECTOR NPTI BADARPUR. Introduction to Supercritical Technology What is Supercritical Pressure ? Critical point in water vapour cycle is a thermodynamic state where there is no clear distinction between liquid and gaseous state of water. Water reaches to this state at a critical pressure above 22.1 MPa and 374 oC.

Aug 21, 2014· Super critical boiler 1. SUPERCRITICAL BOILER SHIVAJI CHOUDHURY 2. What is SUPER CRITICAL The term "supercritical" refers to main steam operating conditions, being above the critical pressure of water (221. bar). Above the critical pressure there is no distinction between steam and water, i.e. above 221. bar, water is a fluid.

The term supercritical in supercritical boilers refers to the pressures above the critical point of water that the boiler is being operated. The critical point of water is at 647 K temperature and 221 bar (22.1 MPa) pressure. Pressures below 221 bar are known as “subcritical pressure” and above 221 bar is “supercritical pressure” of water.

  • EfficiencyA 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 steam.

market price levels. The Hitachi -Naka boiler was designed to be able to burn a wide variety of imported coals, includingthose from Australia, Indonesia, China, U.S.A. and Canada. The main specification of the boiler is summarized in Table 1, and a cross-sectional side view of the boiler is shown in Figure 1. During the engin eering

They operate at supercritical pressure. In contrast to a “subcritical boiler,” a supercritical steam generator operates at such a high pressure (over 3200 psi or 22 MPa) that the physical turbulence that characterizes boiling ceases to occur; the fluid is neither liquid nor gas but a super-critical fluid.

Supercritical boiler that is usually applied to 400 MW systems or larger; the design features a water-cooled dry-bottom furnace, superheater, reheater, economizer, and air heater components. Designed for both base load and full boiler variable pressure load cycling operation as well as on/off cycling operation.

Coal fired power generation is switching over to supercritical (SC) and ultra supercritical (USC) plants which operate with steam on higher temperature and above critical pressure to produce power output at higher thermal efficiency. Due to
