【Ten Years of Rapid Development in Chemical Equipment】Industrial Production of Coal-Based Nanohydrocarbon Fuels from 1970 to 2022

Thread Content

Witness the decade-long rapid development of chemical engineering equipment; praise the prosperity and strength of modern China. Replies will be rewarded – discussions are welcome. -------------------------------------------------- On November 12, 2022, the two technical systems developed by **Energy Group and Zhuneng Group, namely “industrial production of coal-based nanohydrocarbon fuels” and “use of coal-based nanohydrocarbon fuels in thermal power generation,” were recognized by the China Coal Industry Association as being “original both domestically and internationally, and reaching an international leading level.” In March 2021, **Energy Group Juneng Group, relying on its two core businesses of coal mining and thermal power generation, brought together research resources from various sources to focus on technological development, and created two technical systems: \"Industrial production of coal-based nanohydrocarbon fuels\" and \"Use of coal-based nanohydrocarbon fuels in thermal power generation.\" Coal-based nanohydrocarbon fuel is a special liquid coal-based fuel with a particle size at the nanoscale and high surface activity, produced through advanced nanification processes using coal, water, and small amounts of additives. It represents a new type of efficient, clean, and environmentally friendly fuel. Characterized by \"three lows and one high\" – low calorific value of the raw materials, low solid content in the fuel, low ignition temperature, and high fuel calorific value – this fuel can increase the calorific value of coal by 10% to 30% compared to conventional water-coal slurry. It reduces coal consumption for power generation by 50 grams per kilowatt-hour and carbon dioxide emissions by 128 grams per kilowatt-hour, enabling clean combustion that leads to energy savings, reduced consumption, less pollution, and improved efficiency. Based on the properties of coal-based nanohydrocarbon fuels, QuNeng Group has successively completed research on experimental platforms, semi-industrial test rigs, and the industrial application of 150-megawatt circulating fluidized bed boilers. It has carried out research on seven key technologies, including storage and transportation of coal-based nanohydrocarbon fuels before combustion, atomization control, low-temperature ignition, combustion adjustment, efficient separation, air distribution, and ultra-low emissions, thereby establishing a technical framework for power generation using coal-based nanohydrocarbon fuels. To date, the company has successfully ignited coal-based nanohydrocarbon fuels with a concentration of 50%, produced from 4,000 kcal of coal, at low temperatures of 180 to 200°C. It will continue to optimize the production process, thereby paving the way for the flexible transformation of traditional thermal power units. This provides technical support for helping the energy industry achieve its \"dual carbon\" goals and promote the clean and efficient use of coal.
