Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】Continuous updates and summaries available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Recently, the world’s first 110KV solid-regeneration electric steam injection boiler, manufactured by Liaohe Thermal Recovery Machinery Company, was successfully put into use in the Xinjiang oil fields! Along with the clear sound of the switch being closed in the control center of the pilot test station for the 20t/h regenerative electric steam injection boiler at Zone 9 of the Xinjiang Oilfield Heavy Oil Development Company, and the stable data displayed, a new record for green electricity in the energy industry was set: the solid-state regenerative 110KV high-voltage electric steam injection boiler was successfully powered up, and it was able to deliver superheated steam continuously, stably, and efficiently into the steam injection network all the way to the bottom of the wells. This marks another significant technological innovation and breakthrough by Bohai Equipment in the field of new energy and green power applications. 01 Technical Innovation: A masterful solution to overcome industry bottlenecks. The key advantage of the successful operation of this project lies in the innovative design of a integrated process that combines 110kV high-voltage direct supply, resistance heating, solid heat storage, hot air circulation, recycled purified water, and superheated steam generation technology. Unlike traditional fuel and gas steam injection boilers, this device acts as a \"super express train\" in the industrial energy system, delivering 110kV high-voltage electricity from the power grid directly to the boiler’s core heating system. For the application of solid heat storage devices in high-voltage environments, an experimental platform was developed independently to verify and ensure the equipment safety as well as its insulation from ground under direct high-voltage supply. To address the challenge of efficient heat exchange in hot air circulation, hundreds of theoretical wind field simulations were carried out in combination with on-site wind field measurements, in order to determine the structural design of an efficient heat exchange unit and achieve effective conversion and transfer of thermal energy. 02 Lean Construction: Construction Practices for Overcoming Complex Site Conditions. The successful manufacturing, installation, and commissioning of this project were the result of the efforts and expertise of the leaders at Bohai Equipment Company as well as all the employees involved in its construction. Faced with the practical challenges of preheating evaporation, excessive length in the superheating section, heavy weight, high requirements for precise positioning, and limited on-site space, the on-site project team developed a specialized lifting plan, carried out continuous monitoring, and achieved successful precise positioning in just one attempt. Faced with the complex construction involving multiple disciplines such as the equipment itself, steel structures, processes, instrumentation and electrical systems, as well as civil engineering, the on-site team proved its resilience. By relying on digital management, they ensured orderly daily construction activities and strict safety controls, while also properly planning the workspace and timing for different tasks, thus guaranteeing a safe, orderly, and efficient completion of the project. 03 Future Outlook: Fulfilling the Mission of Advancing Green Energy Development. The successful operation and steady steam production of the solid-state heat storage 110KV high-voltage electric steam generator reflect Bohai Equipment’s firm commitment and sense of responsibility toward the green equipment manufacturing industry. The successful commissioning of this world’s first electric boiler represents another milestone for Bohai Equipment in its pursuit of the **\"dual carbon\" goals and the group company’s green and low-carbon strategy. It also shows how Bohai Equipment uses \"green manufacturing\" to strengthen its core competitive advantages, leverages \"green achievements\" to enhance its competitiveness, and relies on a \"green vision\" to fulfill its mission with greater commitment. We will further develop a series of green energy equipment tailored for different applications, in order to create a green energy equipment system that covers the entire process of oil and gas extraction as well as petroleum refining. To build a beautiful China and achieve a clean and low-carbon transformation in the energy sector, as well as to create a new era of smart energy, Bohai Equipment continues to contribute its efforts to writing a new chapter in green development and carbon neutrality!
