Performance of a 35 HP Organic Rankine Cycle Exhaust Gas Powered System 700160

An organic Rankine cycle system utilizing waste exhaust gas heat from a 30 KW gas turbine generator set has been built and tested. Utilizing a new fluorocarbon fluid, the system furnishes 18.9 KW of additional electrical power output along with 120,000 BTU/hour for air heating and 190,000 BTU/hour for water heating for environmental control. The primary gas turbine engine fuel control furnishes the speed control for the mechanically locked-in Rankine turbine and permits fuel saving operation under power sharing conditions from full load to idle conditions. This system concept provides electrical energy output at a fuel consumption rate approaching that of the diesel set but at a small fraction of the diesel set weight.
