The Shaanxi Fandeli Boiler's semi-coke boiler retrofit features a simple water circulation system and a rationally designed pressure-bearing structure, ensuring safe operation under proper water quality conditions. The combustion equipment, a quick-installation grate, is manufactured and assembled in the factory, allowing for direct installation on the foundation upon delivery to the site. With its rational and compact structure, low steel consumption, and superior performance, weight, and dimensions compared to domestic boilers of the same capacity, it demonstrates significant advancements. Our company, Shaanxi Weinan Fandeli Boiler Factory, developed the first semi-coke boiler retrofit based on extensive research and experimentation. This innovation not only addresses the challenges of igniting and fully burning semi-coke but also offers high thermal efficiency, low emissions of SO2, NOx, and soot, making it a new generation of energy-saving and environmentally friendly products. The introduction of specialized semi-coke boilers completely resolves the issue of industrial boilers lacking low-cost clean fuels, and this technology has applied for multiple national patents. In recent years, amid the severe challenges of air pollution control, our company has developed a fully intelligent series of boilers suitable for semi-coke briquettes and semi-coke pellets, based on the combustion characteristics of semi-coke. Tests and inspections confirm that their thermal performance and environmental indicators comply with national and industry standards. Experts believe that since coal accounts for about 70% of China's primary energy structure and it is difficult to significantly increase alternative energy sources in the short term, the clean utilization of coal is essential for combating air pollution. Promoting the use of semi-coke in small boilers is one of the effective measures to reduce atmospheric pollutant emissions in China. A comparative analysis report by the Institute of Earth Environment, Chinese Academy of Sciences, shows that semi-coke has very low emission factors, close to or even better than high-quality anthracite. Using semi-coke for residential and decentralized coal consumption not only serves as an excellent substitute but also significantly reduces haze, with primary PM2.5 emissions reduced by nearly 80%. Given the environmental, economic, and feasibility advantages of semi-coke, Shaanxi Deli Energy Technology Co., Ltd. (Fandeli Boiler Factory) has been committed to the research, development, and production of environmentally friendly boilers. The high-efficiency semi-coke boilers they produce actively contribute to energy conservation, emission reduction, and the reduction of pollutants from coal consumption. In recent years, addressing the嚴(yán)峻形勢 of air pollution control, the company has developed a fully intelligent series of boilers suitable for semi-coke briquettes and pellets, with thermal performance and environmental indicators meeting national and industry standards through testing and inspection.
