盘式磁流体发电机-蒸汽动力装置联合循环热力系统的分析与计算

Thermal System Analysis of A Disc Type MHD Generator Combined with A Steam Power Plant

本文以盘式磁流体发电机为系统的核心.对直接加热、间接加热和混合加热等三种不同氧化剂预热方式所组成的万千瓦级磁流体-蒸汽联合循环中间试验电站的热力系统进行了分析.计算了不同方案联合循环电站的效率,并分析了诸因素的影响.

Taking the disc type MHD generator as the system's attention, the paper makes a analysis of the thermal system of MHD-steam combined cycle pilot power plant of the order of 10MW which are featured by three different ways of preheating the oxidizing agent namely direct heating, indirect heating and hybrid heating. The combined cycle power plant efficiency is calculated for different options, in association with a discussion on the effects of diverse factors.
