1)1条abs = 0杆规= 100 kPa abs =大气压力
- 真空蒸汽一般术语用于在温度低于饱和蒸汽100°C。
例子——沸水One hundred.oC,0条(100 kPa)大气压力
在大气压力(0条g,绝对1条)水的沸点是One hundred.oC和417.51 kJ的能源所需热量1公斤的水0oC蒸发温度One hundred.oC。
因此水的比焓0条g(绝对1条),One hundred.oC是417.51 kJ /公斤。
另一个2257.92 kJ需要的能量蒸发1公斤水的One hundred.oC成1公斤蒸汽的One hundred.oC。因此在0条g (绝对的1条蒸发的比焓2257.19 kJ / kg。
总比焓为蒸汽0杆规是:
h年代= (417.51 kJ /公斤)+ (2257.92 kJ /公斤)
=2675.43焦每千克
例子——沸水170年oC和7条(700 kPa)大气压力
蒸汽在大气压力是有限的实际使用,因为它不能表达自己的压力蒸汽管的使用。在蒸汽分配系统的压力总是比0条计。
在7条g(绝对的8条)水的饱和温度170.42oC。需要更多的热能,提高其温度饱和7条g比时需要水在大气压力。根据表720.94 kJ需要提高1公斤的水0oC饱和温度170年oC。
所需的热能(蒸发焓)7条g蒸发所需的水变成蒸汽实际上小于大气压力。具体的蒸发焓随蒸汽压力。蒸发热量2046.53 kJ /公斤在7条g。
- 注意!蒸汽的比容随压力增加,能源分布相同体积的热量增加。较高的压力,更多的能量可以转移在蒸汽分配系统。
