Internal Technical Report, 60 KW Test Facility Heat Exchanger Specification

PDF Version Also Available for Download.

Description

This report presents the thermal specifications for three heat exchangers (preheater, boiler and condenser) to be used in a 60 kW prototype power plant installed at the Raft River geothermal facility. This prototype plant is unique in that it will utilize a working fluid of 90% propane--10% isopentane (by weight) operating at super-critical pressures in a binary geothermal cycle to extract energy from a 280 F geothermal resource. Studies have shown that this super-critical cycle can provide a net performance about 20% higher than that of the optimum dual-boiling isobutane cycle currently designed for the 5 MW Raft River pilot ... continued below
