车用柴油机余热回收有机朗肯循环系统方案热经济性对比分析
Thermo-economic comparative analysis of different organic Rankine cycle system schemes for vehicle diesel engine waste heat recovery
摘要
Abstract
In order to have a full recovery of the waste heat from a vehicle diesel engine, simple organic Rankine cycle (ORC) system and dual-loop organic Rankine cycle (ORC) system are compared and investigated. According to bench test results of a vehicle six-cylinder diesel engine, the thermodynamic models and economic models of both ORC systems are established, and the thermo-economic comparative analysis of both ORC systems are done on the basis of the study on waste heat characteristics under engine various operating conditions. The results show that, under engine entire operating conditions, net power output, augmentation proportion of power output and improvement of brake specific fuel consumption (BSFC) of the dual-loop ORC system are better than the simple ORC system, the maximum value are 24.38 kW、8.71% and 8.01% separately; Levelized Energy Cost (LEC) of the dual-loop ORC system is 0.8089 CNY·(kW·h)-1 and 19.26% lower than the simple ORC system.关键词
