A steam generating plant consisting of a boiler, an economizer and super heater generates superheated steam at the rate of 50 tons per hr. feedwater enters the boiler at 5 MPa and 120 °C. Steam leaves the superheater at 4.5 MPa and 320 °C. if the coal used has a heating value of 30,000 kJ/kg, calculate the no. of tons of coal fired per hr for Get Price

In contrast to a "subcritical boiler", a supercritical steam generator operates at such a high pressure (over 3,200 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.Get Price
One of the main differences between the superheater and reheater is the steam pressure. The outlet pressure of the superheater in a subcritical drum boiler, for example, is for example at 18.6 MPa, while the outlet pressure of the reheater is only 4.0 MPa.When a supercritical boiler is operated under normal load, the heating surfaces of the reheater and superheater have to …Get Price

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 …Get Price

The steam may emerge wet, dry saturated, or superheated depending on the boiler design. Thermal electrical power generation is one of the major methods. For a thermal power plant the range of pressure may vary from 10 kg/cm2 to super critical pressures and the range of temperature may be from 250°C to 650°C.Get Price
