Improvement of Efficiency of Coal-Fired Steam Power Plant by Reducing Heat Rejection Temperature at Condenser Using Kalina Cycle

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...

Exergy Recovery in Gas Pressure Compression Stations (GPCSs)

The exergy analysis is a proper method for performance evaluation of industrial systems. A generic and detailed analysis of the GPCSs on the second gas pipeline of Iran  is made by the means of exergy. The two main improvement measures of fuel pre-heating and steam injection technologies are presented for the current conventional stations. Steady state equations regarding the second law of ther...

Chemical Cleaning of Fossil Power Station Steam Generators; Past, Present and Future

Technology for chemical cleaning of steam generators at fossil stations was developed during the latter half of the 20 century. Cleaning solvents and processes were developed for application to conventional boilers. The new fleet of combined cycle generating units with heat recovery steam generators (HRSGs) has raised questions concerning the applicability of technology developed for use in con...

Reduced Condenser-Water Flow Rate: Energy-Saving Miracle or Mirage?

The conventional design of air-conditioning plants using large-tonnage chillers calls for a condenser-water flow rate of 3 gallons-perminute-per-ton-of-refrigeration (GPM/TR). For years, this standard has been thought to offer a good balance between first cost and energy cost. Recently, this conventional design has been challenged by proponents of a 2 GPM/TR design. These proponents suggest tha...
