PERFORMANCE SIMULATION OF GAS TURBINE COMBINED HEAT AND POWER

Abstract

Gas turbine engines are gradually being employed in several processes of power generation. The key emphasis of such manufacturing firms is to effectively use fuel as it accumulates money and solves some of the issues that are caused by pollutant emissions. The combined heat and power system represents a highly efficient technology for simultaneously producing heat and power from a single source of fuel. Thus, this project is investigating three separate CHP plant design structures to provide electricity and heat to meet the demand of the domestic district in the UK throughout the year. Some methods have been obtained. In the first step, the demand curves of this selected site are assumed. Then, using TURBOMATCH software, the design and off-design points performance of the two engines (SGT-300 & SGT-600) were explored. Using Excel worksheet, thermodynamic equation for the heat exchanger in a single pressure (“unfired HRSG”) is established following the gas turbines are chosen. The loads which matched throughout the year were obtained in four seasons to depend on four typical days. Even though the results met the requirement, the CHP plant produced more heat than it needed. As a consequence, the combined cycle implemented in this particular sit to reduce the unavoidable waste from the CHP plant. The economic analysis and assessment of this CHP system having a combined cycle showed that it might deliver both great benefits to the site and the highest performance.
