蒸汽

The steam generator, in the incorporate type of the high-temperature gas-cooled reactor, should be of the compact structure, the least heating surface and the higher power density in order to decrease the volume of the initial-stress concrete pressure vessel, there by the steam generator with the uniflow multi-start helical coiled tubes is used generally for it possessing all these characteristics.

资料为硕士论文，包括完整计算过程，及相关设计图纸，推荐下载！摘要在采用一体化布置的高温气冷堆中，为了使预应力混凝土压力容器体积不致过大，蒸汽发生器应尽量紧凑，严格限制受热面空间布置，并要求其具有较高的功率密度。因此，一体化布置的高温气冷反应堆主要选用直流型多头螺旋管式蒸汽发生器。

Including high temperature for the pyrolysis of natural gas to produce carbon black and acetylene; steam reforming of natural gas or partial oxidation of natural gas, synthetic gas can be obtained; natural gas through chlorination, sulfide, nitrification, ammoniated oxide, oxidation can be obtained A N all kinds of derivatives; in the wet gas ethane, propane, butane and natural gas liquid condensate, and so on, the steam cracker or pyrolysis to produce ethylene, propylene and butadiene; dehydrogenation of butane oxidation or produce small Diene or acetic acid, methyl ethyl ketone, and maleic anhydride, and so on.

包括在高温下进行的天然气热裂解，主要生产乙炔和炭黑；天然气蒸汽转化或天然气的部分氧化，可制得合成气；天然气经过氯化、硫化、硝化、氨化氧化、氧化可制得甲烷的各种衍生物；湿性天然气中的乙烷、丙烷、丁烷和天然气凝析液等，经蒸汽裂解或热裂解可生产乙烯、丙烯和丁二烯；丁烷脱氢或氧化可生产丁二烯或醋酸、甲基乙基酮、顺丁烯二酸酐等。

The deaerated head is mostly consisted of shell and primary and secondary deaerated devices, on which there are the Inlet of primary heating steam, and the ports of secondary heating steam and exhaust steam as well as the interface of safety valve.

除氧头主要由筒体、一级除氧装置、二级除氧装置等组成。在其上设有一次加热蒸汽进口、二次加热蒸汽口、排汽口、安全阀接口等组成。

The production practice for three years showed that the phosphorus content and residual solvent in the degummed oil reached the standard, the steam and solvent consumption in the production line of pretreatment and solvent extraction plant were 265 kg/t and less than 0.8 kg/t, respectively.

整个蒸发系统采用全负压工艺技术，充分考虑余热利用，降低蒸汽消耗。从使用3年的情况来看，脱胶油含磷量和残溶达标，预处理车间和浸出车间整条生产线蒸汽消耗为265 kg/t，溶剂消耗小于等于0.8 kg/t。

The purpose of superheating the steam is to ensure that it is fairly dry.

过热蒸汽是为了保证蒸汽相当干燥。

The results show that water hammer pressure is closely related to vaporizing time, and that the frequency of data acquisition is of obvious influence on the fluctuation of water hammer pressure.

在此瞬态的水力过渡过程中，当压力变化降至液体的饱和蒸汽压力以下，在管道中将会有气体和蒸汽析出，并在特定的位置汇集而产生&空穴&，形成水柱分离现象。

When temperature of the steam pipe goes up, the liquid volatilizes into gas, the size expands and produces pressure to impel bellows to stretch.

当蒸汽管线升温时，液体挥发成气体体积膨胀并产生压力推动着波纹管伸长，蒸汽管线降温达到易挥发的液体从气体转变成液体时体积缩收，波纹管内没有推动力，波纹管缩收。
