摘要

基于高效低碳燃气轮机试验装置——轮缘密封试验台(TB03B)

针对1.5级燃气透平前盘腔及鱼嘴密封结构开展了系列的试验研究

并采用CO

示踪法监测燃气入侵。该试验台可系统开展封严效率、燃气入侵、盘腔流动及透平气动综合效率等试验研究。结果表明:该试验台具备1.5级透平试验能力

最高转速3 000 r/min

主气最大质量流量10 kg/s;试验台性能参数均能达到且大部分优于设计指标;封严效率随二次流压比的增大而提高

周向均匀性同步改善;盘腔内高半径处封严效率与静叶叶根处压力梯度呈显著负相关

低半径处受二次流的掺混等影响导致相关性减弱。

Abstract

Based on a dedicated test facility (designated TB03B) for rim seal investigations in high-efficiency low-carbon gas turbines

experimental studies focused on a 1.5-stage turbine forward disc cavity with fish-mouth seal configuration using CO

tracing technique for gas ingestion monitoring. The rig enabled systematic investigations of sealing efficiency

gas intrusion

cavity flow

and turbine aerodynamic comprehensive efficiency. Results show that 1.5-stage turbine testing capability with maximum rotational speed of 3 000 r/min and mainsteam mass flow rate of 10 kg/s

and performance parameters achieved and mostly exceeded design specifications. Sealing efficiency increases with secondary flow pressure ratio while also improving circumferential uniformity. Sealing efficiency at high radius in the cavity exhibits significant negative correlation with pressure gradient at stator blade root

and the correlation is weakened at low radius due to secondary flow m

ixing effects.
