Blue-coke (also known as semi-coke or coke) is a block-structured material with a particle size generally above 3mm and a light black color. Currently, there are two main specifications of blue-coke: one is traditionally produced blue-coke, and the other is mechanically produced blue-coke. Although both types are made from the same high-quality refined coal, differences in production processes and equipment result in varying costs and quality. High-quality blue-coke is primarily produced in Shenmu and Fugu, Shaanxi. Quality standards: Fixed carbon >82%, volatile matter <4%, ash content <6%, sulfur <0.3%, moisture <10%, specific resistance >3500μΩM, particle size: 15-25mm, not exceeding 30mm. Shaanxi Deli Energy Technology Co., Ltd. (formerly Weinan Deli Boiler Factory), established in 1998, is located in the Weinan Economic Development Zone. It covers an area of over 20,000 square meters, with a production workshop of 7,000 square meters and an office area of 2,600 square meters. The company has an annual production capacity of 1,500 MW for hot water boilers. Its main products for blue-coke boiler systems include: large heating chain-grate blue-coke boilers, blue-coke boiler retrofitting, industrial blue-coke boilers, blue-coke hot water boilers, and blue-coke heating boilers. Inquiries are welcome! The products of Shaanxi Deli Energy Technology Co., Ltd. (Fandeli Boiler Factory) have been recognized as "Weinan Famous Brand Products" by the Weinan Municipal Government and the Quality Supervision Bureau. The legal representative, Mr. Fan Gaofeng, was elected as an "Outstanding Technological Innovation Talent of Weinan" (the only honor in the Weinan boiler industry). The company is the only enterprise in Shaanxi specializing in the production of blue-coke boilers, blue-coke boiler retrofitting, and customized dust removal equipment for blue-coke boilers. The blue-coke boilers produced by the company were used as pilot projects by the Weinan Environmental Monitoring Station and put into trial operation. In 2015, the Weinan Environmental Protection Bureau organized a visit for local users to observe and learn from these projects. Additionally, the company has successful cases of retrofitting 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 energy savings. After retrofitting, 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. With three decades of experience in full industrial chain production, it offers customized solutions based on specific needs.
