北方冬季清洁取暖试点推进 12城市奖补219亿元

2017-09-19 17:32:00   中国经济网

当地出台的文件规定,今年天津市中心城区全部燃煤锅炉、滨海新区和环城四区35蒸吨及以下燃煤锅炉、其他区10蒸吨以下燃煤锅炉将实现“清零”。天津市还提出2017年10月至2018年3月,全市PM2.5平均浓度同比下降25%以上,下降至70微克/立方米。

央视记者 张歆:随着我身后的燃气锅炉的组装和即将使用,天津东丽区无瑕街道的3500户居民有望在接下来的采暖季使用燃气供暖。

航空动力控股公司 天津负责人 卢鹏:一期工程的供暖部分现在是用燃气锅炉来进行供暖,我们一期工程的燃气轮机部分将会在明年4月份到5月份左右建成投产,二期工程我们预计是在明年10月份左右建成投产。

该“气代煤”供暖项目1期和2期建成后,预计单期工程每年可节约标煤用量约1.42万吨,节能率27%;减少二氧化碳排放量约7.1万吨,减排率53%; 减少氮氧化物排放约365吨,减排率86%;减少二氧化硫排放量约435吨,减排率99%;减少烟尘排放量约3.6万吨,减排率99.99%。

卢鹏:(燃气)与燃煤供暖相比,它的成本上升大概会到30%左右,在基本上盈利水平比较低的情况下,抓紧要保民生,保供暖。

据统计,京津冀各地也正在推进加快电代煤、气代煤,河北省已完成48万户,户外工程覆盖153万户;北京市外部管网完成451个村,完工率64%,户内清洁取暖设备安装基本实现进村全覆盖。

“散煤清零”攻坚战 农村是难点

除了治理“散乱污”企业,“散煤清零”也是北方清洁采暖的重要方面,也是“最难啃的骨头”。加快散煤治理,可以有效降低供暖季大气污染物排放强度,是减少冬季重污染天气发生的重要一环。

目前,各地在散煤治理上还有较大差距,整个北方城镇中有将近40%、农村有超过90%的地区仍然采取散煤燃烧取暖,散煤仍是农村能源“主力军”,这已成为我国北方地区冬季雾霾的重要原因之一。

据不完全统计,京津冀地区目前每年燃烧的散煤占京津冀地区煤炭用量的十分之一,但对污染物排放量的贡献却达到一半左右。为替代散煤,今年冬天,天津将有50多万户农村居民用上天然气采暖。
