摘要
对乏汽供热用大型射汽器的性能进行了全面分析和研究。结合射汽器的固有特性,在300 MW等级机组的乏汽供热系统中对射汽器变工况性能进行了试验研究,得到了不同机组背压、动力蒸汽压力和出口压力下射汽器的性能曲线。建立了一种射汽器全工况特性的性能参数求解方法。结果表明:性能参数求解结果与试验数据吻合度高。
Comprehensive analysis and research were carried out on the performance of large-scale steam ejectors for exhaust steam heat-supply.Based on the inherent characteristics of the steam injector,the performance of the ejector in the exhaust steam heat supply system of a 300 MW class unit under off-design conditions was experimentally studied.The performance curves of the steam ejector under different turbine back pressures,power steam pressures and outlet pressures were obtained.A solution method for full-operation-condition performance parameters of the steam ejector was established.Results show that the performance parameters are in good agreement with the experimental data.
