AN ASSESSMENT OF THE BRAYTON CYCLE FOR HIGH PERFORMANCE POWER PLANTS R. Schleicher A. R. Raffray C. P. Wong General Atomics University of California, San Diego General Atomics P.O. Box EBU-II, Room P.O. Box San Diego, CA La Jolla, CA San Diego, CA () () () ABSTRACT. Abstract. This report presents the results of a techno-economic analysis (TEA) of a coal-fired utility scale power plant based on the indirect supercritical carbon dioxide (sCO 2) Brayton cycle using an oxy-fired circulating fluidized bed (CFB).A baseline plant configuration was examined as well as three variations to the sCO 2 power cycle examining the impact of reheat (Rht), main compressor. Brayton cycle for coal-fired power plant application Qiao Zhao, Mounir Mecheri, Thibaut Neveux – EDF R&D Romain Privat, Jean-Noël Jaubert-LRGP Nancy March 31st, 5th International Supercritical CO 2 Power Cycles Symposium. San Antonio, Texas. available heat). In , a preliminary study based on a sensitivity analysis of a supercritical CO 2 for coal-fired power plant has been performed to assess the impact of the cycle configurations on its performance. This publication was dealing with several ways to improve the sCO 2 Brayton cycle.
Brayton cycle had enough energy to produce steam in the Rankine cycle. In the s, the advance in gas turbines keeps progressing; therefore the power plants reached 40%% efficiencies and Mw of power. improvement [7, 8]. The combination of the GT Brayton cycle and the ST power plant Rankine cycle complement each other to form efficient CCGT power plants. The Brayton cycle has high source temperature and rejects heat at a temperature that is conveniently used as the energy source for the Rankine cycle plant. The supercritical CO 2 (SCO 2) power cycle, which is highly efficient and cost effective and features a compact structure, is expected to replace steam Rankine cycle and bring technological revolution to coal-fired power obtain the quantitative energy saving potentials of the SCO 2 power cycle, this study compared the thermodynamic performances of coal-fired power plants with SCO 2. Andreas Luzzi, Keith Lovegrove, in Encyclopedia of Energy, Brayton Cycle. The Brayton cycle is the basis of the conventional gas turbine. The cycle involves adiabatic (i.e., insulated) compression of a gas by a compressor turbine, constant pressure addition of heat, and adiabatic expansion in an expansion turbine (usually attached to the same shaft as the compressor), followed by.
One of the main advantages of the S-CO 2 Brayton cycle is its compact turbomachinery. As the system operates beyond the critical point, the minimum pressure is higher (∼7, kPa) than any existing steam Rankine cycle (a few kPa) or gas Brayton cycle (∼ kPa), and thus the fluid remains dense throughout the entire power system. SENSITIVITY PARAMETER ON BRAYTON CYCLE GAS TURBINE In gas turbine plants, sensitivity analyses are carried out by considering the variables describing the system, whose performance is expressed, in terms of power output and conversion efficiency. For each of the variables the corresponding sensitivity.

The in-house code is modified to allow the analysis of three s-CO 2 cycle layouts, simple recuperated Brayton cycle, recompression Brayton cycle, and partial heating Brayton cycle, adopting the isothermal compressor. The cycle performance is evaluated through a sensitivity analysis of cycle design parameters, pressure ratio and flow split ratio.
