飽和蒸汽:
Saturated steam:
1噸燃氣鍋爐飽和蒸汽是我們對水加熱所能直接得到的蒸汽。飽和蒸汽的溫度和壓力、密度是一一對應的,一個大氣壓下的蒸汽溫度就是100℃。如果需要更高溫度的蒸汽,只要提高蒸汽的壓力就行了。
Saturated steam is the steam that we get directly from the heating of water. The temperature, pressure, and density of saturated steam correspond to one another. The vapor temperature at an atmospheric pressure is 100 degrees centigrade. If you need a higher temperature steam, just increase the pressure of the steam.
蒸汽鍋爐在生產飽和蒸汽的時候,由于蒸汽鍋爐本身的一些原因會導致蒸汽中含有水,導致蒸汽的干度不夠,致使飽和蒸汽中帶水的原因主要有以下幾點:
In the production of saturated steam steam boiler, steam boiler for some reason itself will lead to contain water vapor, resulting in the steam is not enough, cause water saturated steam in the following main points:
1、蒸汽鍋爐的負荷。蒸汽鍋爐的負荷如果增加時,有些爐水沒有及時被加熱成蒸汽,會隨著蒸汽流出導致蒸汽帶水。
1 steam boiler load. If the steam boiler load increases, some water has not been heated into steam, with steam steam with water outflow.
2、蒸汽的壓力。蒸汽的壓力增高時,蒸汽帶水的能力增強。壓力高,分子熱運動加強,動能增強,水滴被破碎成微細顆粒易被帶走,同時汽水密度差關系小,分離困難,這些均使蒸汽帶水能力增強。
2. Steam pressure. As the steam pressure increases, the capacity of the steam to carry water increases. The pressure is high, the molecular thermal movement strengthens, the kinetic energy increases, the water droplet is broken into the fine particle, is easy to take away, simultaneously the water vapor density difference is small, the separation is difficult, these all enhanced the steam water capacity.
過熱蒸汽:
Superheated steam:
過熱蒸汽是在飽和蒸汽基礎上進行再加熱而產生的蒸汽。當有水存在時,是產生不了過熱蒸汽的,因為水會吸收熱量產生更多的蒸汽。過熱蒸汽必須通過飽和蒸汽的二次加熱才能產生。過熱蒸汽的溫度與壓力是不對應的。
Superheated steam is steam generated by reheating on saturated steam. When water is present, it does not produce superheated steam because water absorbs heat and produces more steam. Superheated steam must be produced by two heating of saturated steam. The temperature and pressure of superheated steam are not correct.
