Directing against the header system of coal/gas fired boiler in self-supply power plant of Taiyuan Iron and Steel Corporation

a model of boiler behavior and for optimization in boiler load distribution has been established.The optimized calculation of operation data in the field shows that the fuel coal can be saved 0.137 t/h in the event of evaporation capacity needed by the boiler being greater than 520 t/h after optimization;the fuel gas can be saved 30838.44 m3/h in the case of evaporation capacity needed by the boiler being less than 520 t/h.The above-mentioned optimization method for boiler load distribution is suitable to load distritution optimization for boilers with header system.
