Predicting thermal efficiency of a coal stoker fired boiler operating with varying load

摘要

Authors of hte present paper discuss possibility of predicting thermal efficiency of a coal stoker fired boiler operating in transient states.New definition of the thermal efficiency is introduced.Mathematical model of stoker boiler involving kinetices of ther coal combustion.heat and mass transfer is applied and desicribed.Presented mode allows to choose optimial operating parameters for the boiler in real-time.Kinetics of coal combustion was examined during labroatory-scale experiments.
