what is meant by boiler.. Answer / vivek kumar A Boiler may be define as a closed container in which steam is prodused at high preassure and temperature from water by combustion of fossil fuel.

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 – 3,200 psi or 22 MPa.

Answer / babu. As per IBR, the boiler is a closed vessel that holds 22.5 litres of steam at a pressure above atm.

Boiler efficiency is calculated by: Efficiency of boiler is defined as the percentage of heat input that is effectively utilized to generate steam. Boiler efficiency = (Heat output/Heat input) *100 or Boiler efficiency = (Heat in steam output, Kca

In general continuous circulation of flue gases through passages is necessary for efficient operation of the boiler.draught is basically difference of pressure between boiler pressure and atmospheric pressure due to which flow of flue gases occurs

What you meant by this question is uncertain. If you are asking about the definition then Boiler steam pressure is the pressure developed by a water steam boiler, else if you are asking about the

This excess energy is used to convert a portion of this condensate into steam. This phenomenon is called as flashing and the steam so generated is referred to as flash steam. Eg. Consider a process where steam is used at a pressure of 6 bar. At this pressure, the enthalpy of steam would be 659.33 Kcal/Kg.

2011-10-14 · BOILER EFFICIENCY - The term boiler efficiency is often substituted for combustion or thermal efficiency. True boiler efficiency is the measure of fuel-to-steam efficiency. BOILER HORSEPOWER - The evaporation of 34-1/2 lbs of water per hour from a temperature of 212 °F into dry saturated steam at the same temperature. Equivalent to 33,475
