Take 1018 t/h boiler of a 330 MW as monitoring objects, a overall energy-loss model of coal consumption deviation for operation parameters deviating from the target value is established, which is caused by controllable operation parameters deviates from the optimal value. The system consists of data acquisition and pre-processing module, performance calculation module, energy consumption diagnosis analysis module. And boiler operation energy consumption assessment analysis system in power station is developed, which realizes online monitoring the controllable operation parameters of boiler energy loss. The system can help operators to learn the coal consumption deviation of main operational parameters and ensure the unit operating under the optimal consumption condition.
