Formatted Abstract/Summary
The purpose of this paper is to assess the influence of the variation of performance of a Natural Draft Dry Cooling Tower (NDDCT) due to changing ambient temperature, and the effect this has on an Enhanced Geothermal System (EGS) power plant using an Organic Rankine Cycle (ORC). A one dimensional cooling tower model was developed and integrated into a cycle model. The ORC considered is the supercritical butene organic Rankine cycle, with three cycle variations considered; the basic, recuperated and regenerative cycles. The EGS heat source conditions used are those found at the Habanero 1MW pilot plant in South Australia, with geothermal brine inlet temperature of 220oC, minimum brine temperature of 80oC, and brine mass flow rate of 35kg/s. The analysis finds that diurnal variation of net power generation is typically of the order of ± 10%, but in the most extreme case may be as much as ± 30%.
