The condensing length increases with the boiler heating power and air content increasing, while it decreases with the system pressure increasing. under the normal pressure, the wall temperature and the centerline temperature along the condensing length nearly remain constant for pure steam, while they decrease continuously for steam / air mixture. however, when the steam condenses over, the temperatures drops rapidly
常壓下，純凈蒸汽冷凝時，有效冷凝段管壁壁溫基本保持不變，但是當蒸汽冷凝完畢進入過冷水階段后，管壁壁溫會急劇下降；蒸汽中含有空氣時，冷凝管中心溫度變化不大，但管壁壁溫始終呈下降趨勢。Measurements were made of system pressure, mass flow rate of steam, air, and cooling water, temperatures of condensing flow and cooling flow, and the water level of boiler. the major phenomena observed in the present experiment are similar to those by other investigators. the mass flow rate of steam, the system pressure and air content are the most important factors affecting steam condensation
實驗結果表明，維持二次側冷卻水流量不變，無論對于純凈蒸汽還是含有空氣的蒸汽冷凝，隨著蒸汽發生器加熱功率的增大（即蒸汽流量增大） ，有效冷凝段長度將加長；當蒸汽中含有少量空氣，有效冷凝段長度也會明顯加長；提高系統壓力，有效冷凝段長度將縮短。Distilled water or water treated with reverse osmosis ( water captured into vapor so that all solids are left behind and then recaptured into fluid ) are purer and considered safe, but are also more expensive
蒸餾水或者通過反滲透處理的水（首先使水轉化為蒸汽以分離其中的固形物，然後再轉化為水）更為純凈和安全，同時價格更為昂貴。
