Hi experts,

May anyone tells me, what is the common range of approach temperature for an economizer in HRSG of a combined cycle plant?

consider a base case plant, that its performance is only affected by ambient condition. say ambient temperature from 0 to 45 centigrade degrees. and the approach temperature at design is 5 degrees. gas turbine power: 157MW

thanks in advance,
