Laboratory investigation of an advanced geothermal primary heat exchanger (APEX). Final report 2146:08, 30 June 1975 to 31 August 1976
The research program conducted to investigate the feasibility of using a recirculating bed material, fluidized by geothermal brine, to reduce or eliminate fouling in an Advanced Geothermal Primary Heat Exchanger (APEX) is described. The research effort combined theoretical analyses and laboratory experimentation to evaluate and characterize the concept. Technical feasibility was established by testing the effectiveness of the bed material in preventing the fouling of a heat exchanger tube in which simulated geothermal fluid was circulated. Economic feasibility was assessed through analysis in which potential cost savings resulting from the use of the APEX concept in a hypothetical 30 MW electrical power plant were determined in comparison with conventional tube-in-shell heat exchangers.
