The Performance Study and Case Analysis of Dual Source Heating System for Gas-Fired Internal Combustion Engines

On how to use natural gas in a highly efficient and rational way in heating, this dissertation proposed a dual-source heating system with gas internal-combustion engine as thermal power equipment and set up a mathematics model of economic evaluation criterion for this system. Applying to concrete cases, the authors analyze the environment temperature t, the COP (coefficient of performance) of heat pump, the power generation efficiency ξw of gas internal-combustion generating set, which are the main factors that influence the economic evaluation criteria of the system. Under certain conditions, the operational economy of this system is higher than that of heating by natural-gas-fired central-heating boiler.
