Using Two Phase Heat Exchanger in Replacement of Separator for Sabalan Field

Abstract

Sabalan field is located in South West Of Iran and is the first geothermal field. In this paper we are going to compare the conventional single stage geothermal power plants with a vapor rankin cycle which boiler is a heat exchanger. As we know vapor entering the turbine from output of separator contains corrosive minerals that may harm the turbine blades and turbine maintenance costs increases but with replacing separator and using heat exchanger we could inhibit system from corrosion and scaling. It should be noted that after designing the heat exchangers we reached that the rates of output vapor become more of a Separator, and this means that the output of plant goes up, on the other hand, turbine maintenance costs are reduced compared to the Separator.
