What are the main technical indicators for measuring circulating fluidized bed units?

　　Reliability: Equivalent availability factor, number of unplanned outages, unit available hours, etc.

　　Economical efficiency: unit power supply coal consumption, plant power consumption rate, main operating indicators (main steam pressure, main steam temperature, reheat steam temperature, vacuum degree, average feed water temperature, make-up water rate, reheater water spraying volume, boiler efficiency) .

　　Environmental performance: smoke and dust emission concentration, SO2 emission concentration, NOx emission concentration.

　　Other indicators: comprehensive utilization rate of ash and slag, comprehensive water consumption rate for power generation, etc.
