...Jeffrey A. Benoit; Charles Ellis; Joseph Cook The search for power plant sustainability options continues as regulating agencies exert more stringent industrial gas turbine emission requirements on operators. Purchasing power for resale, decomissioning current capabilities altogether...

...Robert W. Bilger; Zhijun Wu Internal combustion Rankine cycle (ICRC) power plants use oxy-fuel firing with recycled water in place of nitrogen to control combustion temperatures. High efficiency and specific power output can be achieved with this cycle, but importantly, the exhaust products...

...Gideon P. Greyvenstein The objective of this paper is to model the steady-state and dynamic operation of a pebble-bed-type high temperature gas-cooled reactor power plant using a system computational fluid dynamics (CFD) approach. System CFD codes are 1D network codes with embedded 2D or even 3D...

...A. I. Zwebek; P. Pilidis This paper presents an investigation of the degradation effects that gas and steam turbine cycles components have on combined cycle (CCGT) power plant performance. Gas turbine component degradation effects were assessed with TurboMatch, the Cranfield Gas Turbine simulation...

...D. Grace, Senior Engineer; J. Scheibel, CT Technical Manager Project developers, insurers, financiers, and maintenance organizations have an interest in quantifying technical risks and evaluating risk mitigation alternatives for combustion turbine (CT) power plants. By identifying exposure to risk...

...M. Gambini; M. Vellini In this paper thermodynamical and economic analyses of fossil-fuel-fired power plants, equipped with systems for CO 2 recovery, are presented. The investigation has been developed with reference to power plants representative both of consolidated technology (i.e., steam cycle...

...G. Ferretti; L. Piroddi In this paper a neural network-based strategy is proposed for the estimation of the NO x emissions in thermal power plants, fed with both oil and methane fuel. A detailed analysis based on a three-dimensional simulator of the combustion chamber has pointed out the local...

...P. Schihl; E. Schwarz; W. Bryzik A special two-cylinder military specific power plant was employed to evaluate the effect of thermal barrier coated pistons on overall engine performance at simulated low heat rejection-type operating conditions. This study focused on three combustion systems...

...S. Pelster; D. Favrat; M. R. von Spakovsky Combined cycle power plants are currently one of the most important options for the construction of new generating capacity as well as for the replacement and repowering of existing units. Due to the complexity and the large number of options...

...J. Bausa; G. Tsatsaronis The fast startup and load-increasing process of power plants is a complex task involving several restrictions that have to be fulfilled simultaneously. An important restriction is the maximum allowed thermal stress of the steam generator pipes and the steam turbines caused...

... the process of rapid load-increase in a single-pressure combined-cycle power plant. The power plant is described with a simplified model that consists of 18 first order ordinary differential equations and 67 algebraic equations. For this model a time-optimal operation associated with a load increase from 50...

...J. H. Horlock; J. B. Young; G. Manfrida The definition of open cycle rational efficiency is unequivocally based on the ratio of the actual shaft work output from a power plant to the maximum work that could be obtained in a reversible process between prescribed inlet and outlet states. However...
