随着中国大气环境治理力度的加大以及我国西气东输工程的实施,北方地区特别是大中城市燃煤锅炉供暖改为燃气锅炉供暖,生态环境将得到有效改善。但在煤改气后,燃料费用增加了2～5倍。使用户的运行成本大幅度上升。因此,如何做好煤改气后的节能工作,是各单位关注并急于解决的问题。
With the intensification of China’s air pollution control and the implementation of China’s West-East Gas Pipeline Project, heating of coal-fired boilers in the northern region, especially in large and medium-sized cities, will be replaced by heating of gas-fired boilers, and the ecological environment will be effectively improved. However, the cost of fuel has increased by 2 to 5 times after the coal is refurbished. The user’s operating costs increased significantly. Therefore, how to make the energy-saving work after changing the coal to gas is the problem that all the units pay attention to and are eager to solve.
