基于EES的Kalina循环系统优化设计

The Optimized Design of Circulatory System Based on EES Software

目前在世界各国中能源消耗主要依赖石油、煤炭、天然气等不可再生资源,各行各业在积极寻求新能源的同时也加大了对节能技术的研究来提高能源的利用率.具体到船舶运输业,由于燃料的利用率不超过50%,有的甚至不到30%,造成了能源的极大浪费.为了提高燃料总能量利用率,以柴油机排放的烟气余热为热源并结合Kalina循环技术,设计一种用于船舶烟气余热回收的Kalina循环动力系统,在此基础上对循环系统的性能做了优化设计,将Kalina动力循环系统与蒸馏系统耦合组成新的一级蒸馏Kalina动力循环系统,以便提高余热回收的利用率.

At present,the energy mainly depends on oil,coal,natural gas and other non-renewable resources.Researchers from all works are not only finding new energy but also increasing the research on energy saving technology to improve energy efficiency.Specific to the shipping industry,because the fuel utilization rate is not more than 50%,some are less than 30%,causing a lot of waste in energy.In order to improve the total energy utilization rate,depending on the heat source from waste heat in flue gas and Kalina cycle,we designed the Karina circulatory power system used for recovery of waste heat from ship flue gas.Based on the system,optimization design was done to improve the utilization rate of waste heat recovery.The Kalina power cycle system is coupled with the distillation system to form a new one step distillation Kalina power cycle system.
