Shaanxi Deli Energy Technology Co., Ltd. (formerly Weinan Deli Boiler Factory) was established in 1998 and 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 annual production capacity for hot water boilers is 1,500 MW. The main products for semi-coke boiler systems include: large heating chain-grate semi-coke boilers, semi-coke boiler retrofitting, industrial semi-coke boilers, semi-coke hot water boilers, and semi-coke heating boilers. Inquiries are welcome! Given the environmental benefits, cost-effectiveness, and feasibility of semi-coke, Shaanxi Deli Energy Technology Co., Ltd. (Fan Deli Boiler Factory) has been committed to the research, development, and production of environmentally friendly boilers. The high-efficiency, eco-friendly semi-coke boilers developed and produced by the company have contributed positively to energy conservation, emission reduction, and the reduction of pollutants from coal consumption. In recent years, in response to the severe challenges of air pollution control, the company has focused on the combustion characteristics of semi-coke and developed a fully intelligent series of boilers suitable for semi-coke briquettes and semi-coke pellets. Tests and inspections have confirmed that their thermal performance and environmental indicators comply with national and industry standards. Experts believe that coal accounts for approximately 70% of China’s primary energy structure, and it is difficult to significantly increase the share of alternative energy sources in the short term. Therefore, the clean utilization of coal is an essential pathway for current air pollution prevention. Promoting the use of semi-coke in small-scale boilers is one of the effective measures to control air pollutant emissions in China.
