Abstract
Taking an ultra supercritical 660 MW unit as the example
the basic formula method was applied to establish an energy-loss analysis model for boiler efficiency
exhaust temperature
oxygen concentration and carbon content in fly ash.The model is able to online calculate the standard coal consumption deviation for power supply.The energy loss analysis was carried out under a certain operation condition.The results show that
this established online boiler energy-loss analysis model is correct and the analysis results are reliable.
