The rectification plan for coal-fired boilers over 20 tons before October 31, 2016, has been announced with four options: 1. Grid connection: Prioritize grid connection for boilers meeting the conditions. 2. Natural gas: Prioritize the use of natural gas where pipeline networks are available. 3. Installation of desulfurization and denitrification equipment: Add such equipment without replacing the coal-fired boilers. 4. Semi-coke: Retrofit coal-fired boilers to use the clean energy source—semi-coke. Industry experts recommend that, among the four options, boilers eligible for grid connection should be prioritized for grid connection. For boilers ineligible for grid connection, retrofitting coal-fired boilers into semi-coke boilers is the preferred choice. This approach significantly reduces equipment investment costs, greatly lowers boiler operating expenses, and fully complies with environmental emission standards. 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 office space of 2,600 square meters. The annual production capacity for hot water boilers is 1,500 MW. The company specializes in semi-coke boiler systems, with main products including: - Large heating chain-grate semi-coke boilers - Semi-coke boiler retrofitting - Industrial semi-coke boilers - Semi-coke hot water boilers - Semi-coke heating boilers Welcome inquiries via phone! The burner structure of semi-coke boilers is specifically designed and manufactured for the characteristics of semi-coke, such as high fixed carbon content, low volatile matter, difficulty in complete combustion, and challenges in ignition. This design differs from that of ordinary coal-fired boilers. As a result, ordinary coal-fired boilers cannot burn semi-coke. Attempting to burn semi-coke in coal-fired boilers may lead to issues such as difficulty in combustion, flameouts, extremely low combustion efficiency, reduced boiler output, higher operating costs due to inefficiency, and disruption of normal heating needs for users. Shaanxi Weinan Deli Boiler Factory has developed a new environmentally friendly semi-coke boiler and specializes in retrofitting coal-fired boilers into semi-coke boilers. The retrofitting includes customized dust removal equipment to ensure easy ignition, easy sealing, and complete combustion of semi-coke. Key features include: - Internal heat exchange tubes designed as threaded smoke tubes, improving thermal efficiency by 5% and featuring self-cleaning functionality. - Oxygen-enriched waste heat preheating for combustion assistance, increasing thermal efficiency by 3% and extending the service life of the grate.
