Core Viewpoint - The project in Pingyuan County utilizes geothermal energy for heating, providing an environmentally friendly alternative to traditional coal heating, thereby addressing issues of high energy consumption, pollution, and financial burden [1][2]. Group 1: Project Overview - The Pingyuan County Western Urban Area Clean Heating Source Replacement Project, constructed by China State Construction Engineering Corporation, marks the first geothermal heating project for the company [1]. - The project commenced in October of the previous year and includes the construction of two geothermal energy stations, with a heating coverage area of 2.02 million square meters, benefiting over 200,000 residents [1][2]. Group 2: Technological Innovations - The project employs a cascading utilization technology that maximizes energy efficiency and achieves 100% recycling of underground water resources [2]. - The geothermal system extracts heat from water at a depth of 1,500 meters, with an initial temperature of 56°C, and utilizes a two-stage heating process to optimize energy use [2]. Group 3: Economic Benefits - Compared to traditional coal heating, the geothermal system reduces the full lifecycle cost by 30%, saving over 20 million yuan in annual financial subsidies [2]. - The heating cost for residents remains at a reasonable level of 21 yuan per square meter, with potential future reductions of 12% through the installation of smart control devices [2]. Group 4: Environmental Impact - The project significantly reduces emissions, including 260 tons of sulfur dioxide, 180 tons of nitrogen oxides, and 86,000 tons of carbon dioxide annually, equivalent to planting 480,000 trees [3].
