An identification model based on principal component analysis which can reflect thermal efficiency is proposed, in order to improve the opera- tion efficiency of boiler. It can monitor the thermal efficiency online and estimate the key influential parameters. The monotonic relationship between thermal efficiency and SPE statistic is verified by large numbers of historical data. When the boiler's operation efficiency decreases, the influential parame- ters can be directly got by contribution plot method, which guide operators in real-time to adjust these and maintain boiler efficient operation. The practice shows that this method is feasible.
