摘　　要：通过对无压锅炉与有压锅炉供热系统水压图的分析和比较 ,发现二者的主要区别在于循环水泵的扬程不同 ,即循环能耗不同。通过分析 ,认为无压锅炉循环能耗绝对大于有压锅炉和两种锅炉相差不大的观点都是片面的。设计者应根据供热系统的特点 ,具体问题具体分析 ,认真进行能耗比较 。Through the analysis and comparison of water pressure chart of press boiler and no-press boiler, it is found that their main difference is circulating pump delivery, namely different consumption. And the idea that the energy consumption of no-press boiler is more than press boiler is one-sided view. Designers should be decided on the analysis and comparison of the heating system character.

关 键 词：无压锅炉 有压锅炉 循环能耗 供热系统 热水采暖
