This paper proposes an approach for improving the plant efficiency by reducing the heat rejection temperature of power cycle using Kalina Cycle System 11 (KCS11) which is integrated at the steam condenser of a 500 MWe SubC (subcritical) coal-fired power plant. It is modelled by using power plant simulation software ‘Cycle Tempo’ at different plant operating conditions. Results show t...

We develop a tractable framework for the analysis of the relationship between contractual incompleteness, technological complementarities, and technology adoption. In our model a …rm chooses its technology and investment levels in contractible activities by suppliers of intermediate inputs. Suppliers then choose investments in noncontractible activities, anticipating payo¤s from an ex post barg...

The dwindling and scarcity of fossil energy sources is the basis transition, where renewable resources are increasingly valued. purpose cogeneration system studied in this article to recover residual heat from gases coming out chimneys cement kilns, produce at same time electricity required for offices residential houses workers. Cement kilns reputed be energy-intensive, generating excessive lo...

In this research, the thermodynamic investigation of the tri-generation system is performed by the first and second law of Thermodynamics. The trigeneration system under study consists of three subsystems including the solar subsystem, Kalina subsystem and lithium bromide-water absorption chiller subsystem. The proposed system generates power, cooling and hot water using solar energy. The syste...

The classical Heckscher-Ohlin-Mundell paradigm states that trade and capital mobility are substitutes, in the sense that trade integration reduces the incentives for capital to ‡ow to capital-scarce countries. In this paper we show that in a world with heterogeneous …nancial development, the classic conclusion does not hold. In particular, in less …nancially developed economies (South), trade a...

ion of Mental Representations: Theoretical Considerations and N eu roscientific Evidence Kalina Christoff and Kamyar Keramatian The ability to conceive of highly abstract concepts is a fundamental feature of human cognition. Using abstract mental representations, we can organize perceptions garnered from disparate experiences, develop novel solutions to problems we encounter, and predict future...

• Novel geothermal systems are proposed for combined cooling and power generation. Parametric multi-objective thermoeconomic optimization comparisons performed. System Conf.
