一、概述 为维持热水供暖系统的运行,每年要耗掉大量的煤、电以及软化水(除氧水)。供热系统节能,就是要节煤、节电和节水。节煤量的多少,受锅炉的运行效率制约,节电量的多少受锅炉辅机及热能输送设备的运行方式制约,而节水(软化水、除氧水)的多少,则受系统的漏水量制约。 I. Overview In order to maintain the operation of the hot water heating system, a large amount of coal, electricity, and demineralized water (oxygen-free water) are consumed each year. Energy-saving heating system is to save coal, save electricity and save water. How much coal is saved depends on the operating efficiency of the boiler. The amount of electricity saved is limited by the operating mode of boiler auxiliary equipment and thermal energy transmission equipment, while the amount of water saving (softened water, deoxidized water) is affected by the water leakage of the system.
