The study of thermodynamic performance of gas CCHP system
摘要
Abstract
Thermodynamic performance is the core and foundation to evaluate the gas distributed energy system,which will also affect other technical performance indicators. This paper introduces a kind of new train thought to redefine conversion efficiency combined with relative energy saving rate and coefficient of energy conservation from the perspective of energy"quality and quantity"and verify some indicators,making up for shortcomings of energy efficiency and conversion efficiency intrinsically. The article focuses on researching the body heat and smoke from leakage,excess air coefficient and incomplete combustion gas affecting thermodynamic performance. Results show that the redefined conversion efficiency and relative energy saving rate and coefficient of energy conservation are accurate and scientific. Reducing the coefficient of thermal conductivity and escape and leakage coefficient by improving the body materials and seal leak ,keeping the coefficient of excess air as 1 . 08-1. 12,controlling combustion temperature under 1800 ℃ and decomposition's partial pressure measures as 0. 3MPa can make the body has high thermodynamic performance.关键词
