GB 2587《热设备能量平衡通则》中规定:能量平衡计算时“原则上以环境温度(如外界空气温度)为基准”。 通常在进行锅炉和工业炉窑的热平衡计算时,基准温度取为0℃,因为焓值计算本身是以0℃为基准温度的。现在改用环境温度为基准,大家一时难以习惯,感到不方便,不适应。 国标中对于采用环境温度为基准,说明“这是考虑到:(1)环境温度比较符合实际。……(2)环境温度有较强的适应性。……(3)用环境温度计算较简单。……”
GB 2587 “Thermal Equipment Energy Balance General Principles” stipulates: In energy balance calculation “in principle, the ambient temperature (such as the outside air temperature) as a reference”. In the calculation of the heat balance between boilers and industrial kilns, the reference temperature is usually taken as 0°C because the enthalpy calculation itself is based on the 0°C reference temperature. Now that we are using the ambient temperature as a benchmark, it is difficult for people to get used to it. It is inconvenient and not suitable. In the national standard, the use of ambient temperature as a reference indicates that “this is taken into account: (1) The ambient temperature is more realistic.... (2) The ambient temperature is more adaptable.... (3) It is easier to calculate with the ambient temperature. ."
