ABSTRACT:
In heat transfer from a warm water source, efficiency is improved in a thermal energy conversion (TEC) by increasing the temperature of heat supplied to a turbine system substantially above the water temperature. This temperature increase is accomplished in a separate system by reacting gaseous ammonia with water to produce sensible heat at a high temperature; the ammonia is later fractionated from the water using lower temperature heat from the existing heat source. A single-stage temperature increase system (TIS), may be used or there may be an addition of a second stage for raising the temperature of the heat supply even higher.
