Preliminary design of an alternative fuels combined cycle propulsion plant for naval ship applications

Abstract

A preliminary design of a coal burning 25,000 H? naval ship propulsion plant was completed. The system consists of a combined Closed Brayton cycle and bottoming RarJcine cycle. Coal combustion capability is achieved by using a Pressurised Fluidized Bed (PFB) heater. A thermodynamic analysis and volume estimate was conducted for various Brayton cycle compressor pressure ratios ( pi TC ) .
