Unformatted text preview: MECH 3020 Spring 2011: Design Project Due last day of classes Project description The design project involves a combined gas-vapor power cycle. The cycle is illustrated at right; ba- sically it involves use of the exhaust gases from a gas turbine cycle (which are typically at a high temperature) to provide the heat to the boiler in a steam power cycle. Because the combined cycle has a relatively high temperature for heat addi- tion (which occurs in the gas cycle), yet recuper- ates the gas exhaust heat (by heating the steam in the vapor cycle), the overall thermal eciency of the combined cycle can be considerably higher than that of the individual gas and vapor cycles alone. compressor regenerator combustor gas turbine boiler re- heat HPT LPT condenser LPP HPP FWH air inlet air exit 1w 2w 3w 4w 5w 6w 7w 8w 1a 2a 3a 4a 5a 6a 8a 7a The gas turbine system consists of a standard Brayton cycle with optional regeneration (note that the dotted lines in the schematic will correspond to optional features in your design).
