Enhance quality awareness and promote high-quality development. ----------------------------------------- Fly ash are tiny particles of ash emitted during the combustion of fuels, mainly coal. Its particle size is generally between 1 and 100 μm. Also known as fly ash or soot ash. Fine solid particulate matter in the ash of flue gases produced by fuel combustion. Such as the fine ash collected from flue gases in coal-fired power plants. Large amounts of fly ash, if left uncontrolled or untreated, can cause air pollution; when it enters water bodies, it can clog rivers, and some of its chemical components are harmful to organisms and humans. In September 2020, the world’s first circulating fluidized bed fly ash incinerator began to operate at full capacity in Gao’an, Jiangxi, capable of burning 500 tons of fly ash per day using pure gas, with a combustion efficiency of 98.5%. By integrating the gasification of fly ash for power generation with circulating fluidized bed coal gasification technology, this project converts coal into clean gas and raw materials for construction materials, thereby providing impetus for the development of new economic activities in the region and facilitating industrial upgrading. It holds great significance for the transformation and sustainable development of the ceramics industry. This fly ash incinerator is Unit 1 of the 3 fly ash incineration units installed for the Jiangxi Jimin Kexin (Gao’an) Clean Industrial Gas Project. The total investment is approximately 6 billion RMB. Upon completion, the project will become the world’s largest coal-based clean industrial gas project, supplying coal-derived clean industrial gas to over 40 enterprises in the ceramic industry base. The ultra-high pressure and ultra-high temperature steam generated by combustion is used for power generation, equipped with 3 waste heat and energy recovery systems, each with a capacity of 45 MW. The fly ash incinerator of this project features a large volume of fly ash to be processed and high steam parameters, which is the first of its kind in the world.
