The present article deals with transient thermal stress calculation on a safety horizontal shell and tube condenser. This condenser is used in power plant for cooling of hot steam diverted from the turbine case its emergency shutdown. standard was provided according to EN 13445 steady regime. As consistent this calculation, an expansion joint must be shell. main aim describe detailed temperatur...

In this publication, we present an energy and exergy analysis of the Szewalski binary vapor cycle based on a model of a supercritical steam power plant. We used energy analysis to conduct a preliminary optimization of the cycle. Exergy loss analysis was employed to perform a comparison of heat-transfer processes, which are essential for hierarchical cycles. The Szewalski binary vapor cycle cons...

Through its ‘Column Targeting Tools’ the Aspen plus simulator performs the ‘Thermal Analysis’ for rigorous column (RadFrac) calculations and produce Column Grand Composite Curves (CGCC) and exergy loss profiles. The CGCC displays the net enthalpies for the actual and ideal operations at each stage, and the cold and hot heat utility requirements, while the exergy loss profiles indicate the level...

Energy and exergy analyses are conducted at the Dieng Geothermal Power Plant to determine energy loss of components by calculating efficiency, rate change in flow, each component. The data were collected on component, including production wells, turbines, main condenser, inter-condensers, cooling towers, with collection occurring from April 2017 March 2018. begin enthalpy entropy both input out...

The present paper describes the energy and exergy analysis of a reheat regenerative vapor power cycle. The plant consists of one boiler feed pump, one supercritical boiler, two steam turbines with a reheater in between, two feed water heaters (one open and one closed) and a condenser. The energy and exergy balance study has been carried-out for each component of the plant. Energy efficiency, ex...

In March 2008, Keppel Seghers started the engineering, supply, construction and commissioning of a Combined Heat and Power (CHP) Waste-to-Energy (WtE) plant in Åmotfors (Sweden). When completed in 2010 the plant will process close to 74,000 tons per year of household waste (average LHV = 10.5 MJ/kg) and limited quantities of (demolition) wood resulting in a yearly production of about 108,700 MW...

This paper describes a construction and characteristics of a coal-gas-burning high e ciency power plant which emits no carbon dioxide (CO 2 ) into the atmosphere. In the plant, CO 2 gas and superheated steam are used as the main and sub working uid, respectively, of a closed dual uid gas turbine power generation system. It is assumed that a coal gas whose principal compositions are CO, H 2 , CO...
