Analysis is made to configuration of standby boiler system during start-up of independent coking plant and to the energy saving and environmental issues.The result shows that natural gas or COG is the first priority to use for main boiler start-up,and COG is the first priority for standby boiler.Boiler with two kinds of parameters shall be taken for preference for volume selection.Low-position deaerator shall enjoy priority for boiler system arrangement.DeNOx and DeSOx systems should be used for treatment of emission from the boiler.
