Abstract
A shipboard engine system and method of operating includes two compressors with an intercooler, a compressor turbine, a power turbine, a combustor for combining fuel, air and water. Heat exchangers remove heat from the exhaust and use it to preheat the water to the combustor. Spray condensers recover water from the exhaust for reuse. Water purification apparatus is used to remove acid from the water. The system is designed for stoichiometric operation at full load and run with increased efficiency at part load to give a total lower fuel consumption.
