STUDYING THE EFFICIENCY OF SECONDARY HEAT CONVERSION GAS PISTON INSTALLATIONS INTO ELECTRIC ENERGY
Keywords:
gas engine, recycling of secondary heat, thermal power installation, power generation, modeling of the most efficient thermal conditions.Abstract
A scheme has been developed for utilization of secondary heat of gas engine by converting it into electrical energy using a two-circuit thermal power installation with various working substances in the circuits. A method and an algorithm for calculating the most efficient thermal regime of the installation under the conditions of specified limitations on temperature pressures in heat exchangers have been developed. On the basis of mathematical modeling of thermal conditions, it was found that under the conditions of the gas engine JMS 620 it is possible to utilize up to 3,800 kW of thermal power and generate up to 500 kW of electrical power. The efficiency of conversion of secondary heat into electricity reaches 13.0%, which leads to an increase in the overall efficiency of the gas engine for generating electricity from 42.9 to 50.0%.
