贵州大龙经济开发区：一根热力管串起百亿集群

Core Viewpoint - The establishment of a long-distance heating pipeline in Guizhou's Dalong Economic Development Zone significantly enhances energy efficiency and reduces costs for local enterprises while promoting environmental sustainability [1][2]. Group 1: Infrastructure Development - The Guizhou Dalong Baitong Huiyuan Heating Company has constructed the province's first ultra-long-distance heating pipeline, which is approximately 27 kilometers long and can deliver 200 tons of steam per hour [1]. - The main pipeline, with a diameter of 300 millimeters or more, spans about 19 kilometers, supplying steam purchased from Huadian Dalong Branch to 11 new functional materials enterprises in the park [1]. Group 2: Economic Impact - The centralized heating system allows enterprises to save over 20 million yuan annually in energy costs compared to using their own boilers, with one major enterprise using approximately 270,000 tons of steam per year, accounting for 40% of the total heating supply in the development zone [1]. - From January to April this year, the company delivered 195,000 tons of steam, resulting in a reduction of 130,000 tons of carbon emissions and saving 50,000 tons of standard coal, generating a production value of 40 million yuan [2]. Group 3: Future Plans - The company plans to expand its heating network by constructing two additional pipelines, which are expected to add 200,000 tons of heat energy per year to meet the growing demand from industrial enterprises in the development zone [2]. - The green pipeline not only serves as a means of energy delivery but also acts as a vital link in developing a billion-yuan new energy materials industry cluster, ensuring robust energy support for enterprise growth while fostering ecological and economic benefits [2].
