跨越80公里,“石热入济”背后的创新密码

Core Viewpoint - The company has successfully tackled the challenges of long-distance heating supply through innovative technologies, ensuring reliable heating for users in Jinan City, while also contributing to the company's transformation into a comprehensive energy service provider [2][5]. Group 1: Long-Distance Heating Challenges - The company identified three core challenges in long-distance heating: excessive heat loss, pressure imbalance in the pipeline, and complex hydraulic conditions, especially during extreme winter weather [2]. - A specialized technical team was formed to innovate and implement a large temperature difference heating technology, reducing heat loss rates to industry-leading levels [2]. - The installation of intelligent booster pump stations at key pipeline nodes allows for real-time adjustments to pressure and flow, ensuring consistent temperature and pressure over the 80-kilometer pipeline, achieving a 100% compliance rate for end-user room temperatures [2][3]. Group 2: Intelligent Control System - The company has developed a multi-source backup intelligent control system, which includes a DN1200 steam main pipe and interlinked steam extraction from six units, creating a "one loss, multiple supplements" heating structure [3]. - This innovative design allows for quick compensation of heat supply in case of a single unit failure, preventing any impact on user heating [3]. - The establishment of an "Electric-Heat Collaborative Efficiency Center" integrates real-time data and predictive models to dynamically adjust heating supply based on demand, ensuring stable room temperatures during cold waves [3]. Group 3: Comprehensive Benefits from Innovation - The company has implemented a "three modifications linkage" technology upgrade, enhancing the heating capacity from the original level to 2420 MW, supporting a total heating output of over 13 million GJ [4]. - The introduction of a mobile heating model with 100% capacity steam transportation technology allows for rapid response to heating needs in remote areas and for dispersed users [4]. - The heating business has become a new profit growth point for the company, with a projected heating output of 13.68 million GJ in 2025, representing a 49% year-on-year increase, contributing to the company's turnaround [4]. Group 4: Strategic Impact - The "Stone Heat into Jinan" project has successfully coordinated cross-regional policies and resources, achieving breakthroughs in long-distance heating technology and multi-unit integrated control [5]. - This achievement not only provides a replicable model for cross-regional heating but also demonstrates the company's commitment to high-quality development driven by technological innovation [5].
