随着节能减排工作的进一步推进,近年来我国对城市燃煤锅炉进行了“煤改气”的工作,如何提高天然气直接采暖的系统效率显得尤为重要,燃气壁挂锅炉组成的独立采暖系统不失为一种较理想的选择。目前,在我国北方地区,特别是天然气长输管线沿途的大城市,包括长江三角洲比较富裕的地 With the further promotion of energy conservation and emission reduction, in recent years, China’s city coal-fired boilers have been “coal to gas” work, how to improve the efficiency of natural gas heating system is particularly important, independent heating system composed of gas wall-mounted boiler after all, A better choice. At present, in the northern regions of our country, especially in major cities along the long-distance natural gas pipeline, including the richer Yangtze River Delta
