Thermodynamic analysis of combined power cycle, combining heat from a waste heat source with sub-cycles

نویسندگان

چکیده

Significantly increasing consumption and demand in conventional fossil energy sources require to be more efficient sustainable. In this study, it is aimed increase the efficiency of systems by using thermodynamic cycles from waste heat sources. The designed system at adding sub-cycles a gas turbine. results analyzed with engineering equation solver program, when all are combined, 75% total exergy 24%. Brayton cycle evaluated alone, 65%, 14%. S-CO2 23% 11%. ORC 19% 22%. Rankine 17% 88%. Turbine inlet temperatures tend decrease as destruction also affects subcomponents.

Thermodynamic Analysis of a Waste Heat Driven Vuilleumier Cycle Heat Pump

A Vuilleumier (VM) cycle heat pump is a closed gas cycle driven by heat energy. It has the highest performance among all known heat driven technologies. In this paper, two thermodynamic analyses, including energy and exergy analysis, are carried out to evaluate the application of a VM cycle heat pump for waste heat utilization. For a prototype VM cycle heat pump, equations for theoretical and a...

Thermodynamic analysis of a magnetohydrodyamic oldroyd 8-constant fluid in a vertical channel with heat source and slippage

Thermodynamic analysis of a steady state flow and heat transfer of an Oldroyd 8-constant fluid with effect of heat source, velocity slip and buoyancy force under tranverse a magnetic field is is carried out in this paper. The model for momentum and energy balance is tackled numerically using Method of Weighted Residual (MWR). Partition method is used to minimize the associated residuals. The re...

Quantum thermodynamic cycles and quantum heat engines.

In order to describe quantum heat engines, here we systematically study isothermal and isochoric processes for quantum thermodynamic cycles. Based on these results the quantum versions of both the Carnot heat engine and the Otto heat engine are defined without ambiguities. We also study the properties of quantum Carnot and Otto heat engines in comparison with their classical counterparts. Relat...

Transient Three-Dimensional Thermal Analysis of a Slab with internal heat generation and heated by a Point Moving Heat Source

In this work, analysis of transient three-dimensional heat transfer in a slab with internal heat generation and heated by a point moving heat source along its axis is carried out using integral transforms methods. The heat input into slab or workpiece by the moving heat source is considered in the model. From the results, it was established that the temperature of the material during the heat t...

Waste Heat to Power Systems

Waste heat to power (WHP) is the process of capturing heat discarded by an existing industrial process and using that heat to generate power (see Figure 1). Energyintensive industrial processes—such as those occurring at refineries, steel mills, glass furnaces, and cement kilns—all release hot exhaust gases and waste streams that can be harnessed with wellestablished technologies to generate el...
