GEOTHERMAL-ENERGY NEEDED - EFFECTIVE HEAT-TRANSFER EQUIPMENT

There can be no large-scale application of geothermal energy from steam and hot water without effective heat exchange equipment to overcome the fouling and corrosion from such pollutants as silica, lime, CO//2, and sulfurous compounds that impede efficient heat transfer. The problems are formidable with regard to both binary cycle units and refrigeration systems. 20 refs.
