steam boiler thermal efficiency thermal power

Advanced steam technology - Wikipedia

While high overall thermal efficiency may be difficult to achieve, largely due to the extra stage of generating a working fluid between combustion and power delivery attributable mainly to leakages and heat losses,: 5461 the separation of the processes allows specific problems to be addressed at each stage without revising the whole system

Notice that the thermal efficiency is slightly more than that of the previous example with an open feedwater heater, however with even less power output. In practice one normally finds a combination of open and closed feedwater heaters, and in the Gavin power plant there are seven closed feedwater heaters and one de-aerator/open feedwater heater.

Industrial Boiler Efficiency Calculation & Factors

Thermal efficiency assesses the effectiveness of the heat exchanger by analyzing its ability to transfer heat energy to the water or steam within the boiler. However, this calculation does not account for external factors such as ON-OFF losses, radiation losses, convection losses and more, so it is not the best indication of the boilers' fuel

When this boiler works at 90% efficiency, the thermal power is 71 Gcal/h. Due to the high stack gas temperature of the boiler, a 3.5% efficiency loss occurs and the thermal power reduces by 2.4 Gcal/h to 68.6 Gcal/h. The economic loss is calculated as $79.2/h.
