各种能源在使用及加热过程中并不能完全燃烧,实际产生的热值均低于理论热值,根据各种热源的热效率,将其实际热值列表如下(数据仅作参考):
All kinds of heat source can't be fully burnt in using and heating course, and the actual calorific value are below the theory. According to heat effeciency from different heat sources, the actual calorific value are tabulated as follows:
名称 name |
理论热值 theory calorific value |
热效率 heat effeciency |
实际热值 catual calorific value |
电热水器 | 860千卡/度 | 90% | 774千卡/度 |
液化气 | 10800千卡/度 | 65% | 7020千卡/度 |
天然气 | 8600千卡/立方米 | 70% | 6020千卡/立方米 |
管道煤气 | 3800千卡/立方米 | 65% | 2470千卡/立方米 |
柴油 | 10200千卡/立方米 | 75% | 7650千卡/立方米 |
