Design and performance calculations of chemically recuperated gas turbine on ship

This paper describes the design and performance analysis of a chemically recuperated gas turbine powering a ship. The system studied consisted of an efficient steam-generating system, a reforming regenerator, and a gas turbine. Mathematical models were built for the performance analyses. An efficient steam-generating system was designed and the effects of various parameters on the steam generation were studied. The calculations indicate that the steam-generating system can meet the steam requirements for reforming and fresh water needs of the ship. The diesel steam-reforming reaction was adopted for heat recuperation, and the reaction degrees were analyzed under different conditions. It was found that the reforming regenerator recovered heat from the waste gas to reform the fuel leading to improved combustion. The performance analysis shows that the chemically recuperated gas turbine has a higher thermal efficiency and consequently delivers more power. The steam reforming cycle has a low reaction degree a...
