Abstract

A novel cycle called the low-temperature heat engine system (LTES) has been analyzed for application to geothermal power plants. Powerful computer simulation routines have been utilized. Interim results using a blended working fluid in a portion of the system show better than 40% improvement in power output compared to a modern dual-flash steam plant operating under the same conditions and with the same brine flow. Priority areas for further investigation are discussed. The LTES cycle can also be applied as a retrofit to existing conventional fossil-fueled and nuclear power plants to increase output for a given fuel consumption while mitigating thermal and unit stack gas pollution
