application of cogeneration systems based gas turbine for heat and power production is increasing. because of finite natural energy resources and increasing energy demand the cost effective design of energy systems is essential. cgam problem as a cogeneration system is considered here for analyzing. two new approaches are considered, first in thermodynamic model of gas turbine and cogeneration ...

In this paper, an alternative micro-gas turbine is proposed, where the traditional compressor-turbine arrangement replaced by axial, throughflow wave rotor. The investigated rotor features symmetrically cambered wall profiles and angled port for shaft power extraction uses shock rarefaction waves pressure exchange to achieve gas compression expansion within a single device. A validated quasi-on...

Abstract Supercritical CO2 (sCO2) power cycles have gained prominence for their expected excellent performance and compactness. Among benefits, they may potentially reduce the cost of Concentrated Solar Power (CSP) plants. Because critical temperature is close to ambient temperatures in areas with good solar irradiation, dry cooling penalise efficiency sCO2 CSP Recent research has investigated ...

• A single heated cascade sCO 2 cycle is studied as bottomer of a 4.7 MW gas turbine. Around 1500 kW net electric power can be recovered by the -based technology. The specific cost considered technology around 2000 $/kW. Performance investigated similar to one partial heating cycle. Driving compressor at same rotational speed turbines not possible. Among technological solutions that applied was...

This report summarizes work to examine interstage heating and cooling options for multiple reheat helium Brayton cycle power conversion system (PCS) designs. Previous work has demonstrated that thermal powers in the range of 2400 MWt can be readily derived from combining multiple single-expansion units derived from the 600-MWt, vertical shaft gas-turbine module helium reactor (GT-MHR). This PCS...

In this paper a gas turbine power plant including air preheater (recuperator), heat recovery steam generator and air cooler system was modeled. Eight parameters were selected as the design variables.  Fast and elitist non-dominated sorting genetic algorithm (NSGA-II) was applied (to maximize the exergy efficiency and to minimize the total cost rate) for the mentioned cogeneration system. Th...

Hydrogen is increasingly being viewed as a significant fuel for future industrial processes it offers pathways to zero emission. The UK sees hydrogen one of handful low-carbon solutions transition net zero. Currently, most production from steam reforming natural gas or coal gasification, both which involve the release carbon dioxide. mini decentralised grids via thermochemical process, coupled ...
