Shaanxi Deli Energy Technology Co., Ltd., under its subsidiary Fandeli Boiler Plant, has been recognized by the Weinan Municipal Government and the Quality Supervision Bureau for its products as "Weinan Famous Brand Products." The legal representative, Mr. Fan Gaofeng, was elected as an "Outstanding Technological Innovation Talent of Weinan" (the only such honor in Weinan's boiler industry). The company is the only enterprise in Shaanxi specializing in the production and modification of blue-coke boilers, as well as the customized design and transformation of dust removal equipment for blue-coke boilers. The blue-coke boilers manufactured by the company were adopted as pilot projects by the Weinan Environmental Monitoring Station and put into trial use. In 2015, the Municipal Environmental Protection Bureau organized a visit for numerous users in Weinan to observe and learn from these projects. Additionally, the company has successful cases of modifying various types of blue-coke boilers, including blue-coke hot water heating boilers, blue-coke bathing boilers, and industrial steam pressure boilers. It also develops and produces customized dust removal equipment tailored to the characteristics of blue-coke boilers, ensuring sufficient output while meeting environmental emission standards and achieving certain energy-saving effects. After modification, the boilers are easy to seal, ignite, and ensure full combustion of blue-coke. With 30 years of experience in boiler manufacturing, the company is committed to developing products with independent intellectual property rights for China and has been granted 46 national patents. Its three decades of experience across the entire industrial chain enable customized solutions based on specific needs. The burner structure of blue-coke boilers is specifically designed and produced to address the characteristics of blue-coke, such as high solid carbon content, low volatile matter, difficulty in complete combustion, and challenges in ignition. This design differs significantly from that of ordinary coal-fired boilers, making it impossible for conventional coal-fired boilers to burn blue-coke efficiently. Attempting to burn blue-coke in coal-fired boilers results in issues such as poor combustion, flameouts, extremely low burnout rates, reduced boiler output, increased operational costs due to high energy consumption and low efficiency, and disruption of users' heating needs. Shaanxi Weinan Fandeli Boiler Plant has developed a new environmentally friendly blue-coke boiler and specializes in modifying coal-fired boilers to burn blue-coke. The company designs unique dust removal equipment to ensure that modified blue-coke boilers are easy to ignite, seal, and achieve full combustion of blue-coke. Key features include: - Internal heat exchange tubes designed as threaded smoke tubes, improving thermal efficiency by 5% and featuring self-cleaning capabilities. - Oxygen-enriched waste heat preheating for combustion support, increasing thermal efficiency by 3% and extending the service life of the grate. The promotion and use of blue-coke boilers have provided hope for manufacturers using coal-fired boilers. Recognizing the significant demand in this environmental sector, Shaanxi Weinan Fandeli Boiler Plant, leveraging the strong capabilities of its parent company and its unique technological R&D advantages, has undertaken rigorous technical challenges. Addressing issues such as low volatile matter in blue-coke, delayed ignition, and the presence of unburned carbon particles in the exhaust, the company has conducted in-depth research and continuous innovation based on existing chain-grate boilers. It has developed a comprehensive set of blue-coke combustion technologies that thoroughly resolve these problems, resulting in the creation of new environmentally friendly blue-coke boilers and customized dust removal equipment designed specifically for blue-coke boiler characteristics.
