【摘要】 <正> 一、前言 研究混合气中含有湿蒸汽凝结的透平工作过程是能源有效利用中的一个实际课题。过程的特点是气体部份的流量不断变化,凝结释放的潜热不断加热主流,排气温度将比不含蒸汽凝结的情况为高,且输出功增加。凝结释热过程也使透平内部流场发生变化。更多还原

【Abstract】 After introducing the basic relation and fundamental equations of gas turbines containing wet steam condensation, a simple method is suggested on the basis of replacing the condensation and heat release process thermodynamically by an equivalent poly-tropic process such that usual gas medium calculation program conld. be employed and performance prediction could be easily made. Calculated performance of such turbo expander shows good agreement with tested results.更多还原
