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...

This Software for Design Activity in power plants Equipments helps the power plant engineers and managers to manage the development and design activities of equipments in the field of power plants. This paper is basically concerned with the computerization of the design activity of Condenser, vital equipment in Heat Exchanger Unit (HEU) of Thermal power plant required for condensing the steam a...

The corona discharge in the steam is investigated theoretically and experimentally in means of implementation with the steam condenser for the improved phase-change rate. The considered phenomena include the nucleation of water vapor on mobile charge carriers, the electrohydrodynamic vapor flow toward the condenser wall and the thermodynamics of the charged micro-droplet. The average size of mi...

The Graz Cycle, a hydrogen oxygen fired double loop high temperature steam cycle, combining gas turbine philosophy with steam plant praxis, can be adapted for combustion of methane with oxygen. The resulting combustion products carbon dioxide and hydrogen oxide, i.e. high temperature steam, are mixed with cooling steam and expanded to lowest pressure and temperature. By condensing the steam, se...

The principal leak detection system for primary to secondary leaks is monitoring of the Nitrogen-16 activity in the live steam at the exit of the steam generators (SG). This is supplemented by tritium measurement in the condensate or feedwater, Xenon measurement in the incondensible gases exhausted from the condenser and radioelement detection in the steam generator blowdowns. Tritium is especi...

Jet-refrigeration cycles seem to provide an interesting solution to the increasing interest in environment protection and the need for energy saving due to their low plant costs, reliability and possibility to use water as operating fluid. A steam/steam ejector cycle refrigerator is investigated introducing a two-stage ejector with annular primary at the second stage. The steady_state refrigera...

an industrial gas turbine has the characteristic of decreasing output power on hot summer days while electricity demand peaks. steam injection in gas turbines has been used for many years to prevent the loss of performance of gas turbines caused by high ambient temperature. vodoley system is a closed steam injection gas turbine cycle (csigtc), which is known as a self-sufficient in steam produc...

The article describes the technological scheme and principle of operation a pyrolysis bioenergy plant (PBEP) with recuperative heat exchanger, which simultaneously provides hot water, gaseous liquid biofuels to consumer. results mathematical modeling exchange processes in condenser are presented order identify optimal thermal parameters for cooling biomass steam. A model balance “mixing-displac...
