Steaming in Boiler,HRSG Economizers

In conventional boilers or steam generators,steaming is not a concern. The ratio of gas flow to steam remains nearly constant at all boiler loads,as we reduce the air flows when steam demand or load decreases.Hence the economizer duty is such that the enthalpy absorbed at low loads is lower.The figure above shows the boiler vs HRSG water exit
