- 针对短时间大流量蒸汽引射系统的用汽需求,采用锅炉-蓄热器式供汽系统方案并进行该系统的方案设计和验证试验。从供汽系统组成和工作原理出发,结合引射用汽要求,进行系统性能、结构与测控方案设计。系统性能与结构方案设计包括热力计算、结构选型和蒸汽管道设计,通过热力计算得到充放汽压力、蓄热器体积和蓄热量等参数,结合理论计算和规范系列进行锅炉和蓄热器结构选型,通过充放汽原理和现场情况进行蒸汽管道的布局、尺寸和压降设计计算; 系统测控方案设计部分包括功能分析及方案选择、测点布置、阀门选型。以某液体发动机高空模拟试验台蒸汽引射用锅炉-蓄热器式供汽系统(用汽时间不大于300 s,最大蒸汽流量为94 t/h,用汽压力为0.8 MPa)为案例进行方案设计,通过试验验证了系统的工作性能良好。研究结果可为类似工况下锅炉-蓄热器式供汽系统的方案设计提供参考。
- Abstract:
- Aiming at the steam demand of the short-time and large flow rate steam ejection system, a boiler-accumulator steam supply system scheme is adopted, and the scheme design and verification test of the system are carried out. Based on the system composition and working principle, combined with the steam consumption requirements for steam ejection, the system performance, structure, measurement and control scheme are designed. The system performance and structural scheme design include thermodynamic calculation, structural selection and steam pipeline design. The parameters such as charging and discharging pressure, accumulator volume and heat storage capacity are obtained through the thermodynamic calculation. The selection of boiler and accumulator structure is based on theoretical calculation and standard series. The layout, size and pressure drop of steam pipelines are designed and calculated based on the principle of steam charging and discharging and on-site conditions. The system measurement and control scheme design include functional analysis and scheme selection, measurement point layout, and valve selection. A boiler-accumulator steam supply system used in a steam ejection type high altitude simulation test system of a liquid rocket engine is taken as the case study for scheme design(with a working time of no more than 300 s, maximum steam consumption of 94 t/h, and ejection steam pressure of 0.8 MPa), and the system performance is verified through tests. The research results can provide reference for the scheme design of boiler-accumulator steam supply systems under similar working conditions.
