Cycle Efficiency - an overview | ScienceDirect Topics

The steam in a reheat Rankine cycle leaves the boiler and enters the turbine at 60 bar and 390 °C. It leaves the condenser as a saturated liquid. The steam is expanded in the high-pressure turbine to a pressure of 13 bar and reheated in the boiler at 390 °C. It then enters the low-pressure turbine, where it expends to a pressure of 0.16 bar.

FUNDAMENTALS OF COMBUSTION AND HEAT LOSSES

2  · COMBUSTION PROCESSES have been, are and will be for the near future, the prime generator of energy in our civilization, which is burning fossil fuels at an ever-increasing rate. The processes must be managed well for the sake of the environment and the sustainability of civilization. The principles of combustion are common to heaters, boilers and other forms of industrial combustion, e.g. in

Boiler Efficiency - Boiler and Pressure Vessel

2009-1-31 · Do not unfairly blame the boiler for problems elsewhere in the plant. Remember that the boiler cannot count a "running start" from anything. The biggest player is normally feedwater temperature. Discount the heat in the feedwater from the heat in the steam leaving the boiler. The next thing to be considered is the steam meter on the boiler.

Boiler Introduction | CleanBoiler.org

As the boiler is 'turned-down' to run at less than capacity, efficiency typically drops. To counter this situation, a modular boiler bank of 3 or more boilers with a programmed controller can improve operational efficiency over a single boiler operating in a turn-down mode, and provides a certain amount of redundancy for back-up.
