The new high-efficiency coal combustion additives, CHARNA C and CHARNA C02, developed jointly by a scientific team led by Dr. Jiang Biao, director of the Shanghai Institute of Organic Chemistry under the Chinese Academy of Sciences, and Beijing Jinyuan Chemical Group Co., Ltd., have been successfully developed and recently passed expert evaluation. It is reported that nearly 20 tons of this coal-firing additive were used to conduct boiler combustion performance tests in more than a dozen organizations, including Panyu Titanium Co., Ltd. under Panzhihua Iron and Steel Group, as well as the Beijing Coal Chemical Engineering Research Institute affiliated with the Chinese Academy of Coal Sciences. The test results showed that coal consumption was reduced by 7% to 12%, sulfur dioxide emissions were cut by 24% to 33%, and nitrogen oxide emissions were reduced by around 17%. Due to its excellent energy-saving and emission-reduction effects, many large thermal power companies in China have shown great interest in it, and it has been put into use in some of these companies. The research findings of this project have received significant attention from the State Council and the Ministry of Environmental Protection. In particular, CHARNA C was recognized as a \"key new technology and product for energy conservation and environmental protection in China,\" and it was listed by the National Development and Reform Commission as a key project for the promotion of energy-saving technologies. It is predicted that over the next 20 years, China’s energy demand will continue to grow at a rapid pace. Specifically, domestic coal demand was 1.4 billion tons in 2005, reached 1.55 billion tons in 2010, and is expected to reach 2 billion tons by 2020. For a considerable period in the future, coal will remain the main energy source in our country. According to statistics, more than 85% of the total amount of carbon-based fuels consumed in our country is used for direct combustion in applications such as thermal power generation, industrial boilers, industrial furnaces, and household stoves. According to statistics, in 2005, sulfur dioxide and particulate matter emitted from coal combustion accounted for approximately 90% and 70% of the country’s total emissions respectively, while carbon dioxide and nitrogen oxides accounted for around 80% and 65% of the total national emissions respectively. It is understood that various research institutions at home and abroad have currently carried out research on coal combustion additives and made certain progress, with some of these products already available for sale. However, due to the actual performance, there are numerous issues related to safety, stability, cost-effectiveness, and production feasibility during use, which makes widespread adoption difficult; to date, no products that can be used on a large scale have been developed. According to Jiang Biao, this new type of efficient coal combustion additive differs from the additives currently available on the market in the following ways: First, its mechanism of action is different; the new coal combustion additive is a radical-based efficient catalyst that has been developed based on the principles of coal combustion and taking into account the actual combustion process ； Secondly, it offers significant economic benefits; from the perspective of overall economic efficiency, the catalytic combustion-enhancing effect of the new coal combustion additives is notable, and the economic returns are considerable ； Thirdly, the new type of coal combustion additive serves three functions at once: it acts as a catalyst to enhance combustion, reduces pollutant emissions, and cleans the equipment – features that other products on the market simply do not possess ； Fourth, the new coal combustion additive is in liquid form, making it easy to mix and inexpensive; the amount required is much smaller compared to other additives, hence less usage is needed ； V. The worse the quality of the coal, the more significant the effects achieved by using new coal combustion additives, and the better the economic benefits. While offering both fuel savings and environmental benefits, the new coal combustion additive is easy to use – no additional equipment is required. It can be injected together with coal powder using the existing injection systems, or it can be added in spray form during the fuel transfer process on conveyor belts. It can be widely applied in various coal-fired boilers such as coal powder boilers, chain grate boilers, and circulating fluidized bed boilers. Jiang Biao emphasized that as China places increasing emphasis on environmental protection, all existing coal-fired boilers in the country represent potential customers for coal combustion catalysts; the market is huge, offering great prospects for industrialization.
