摘要：

The pulverized coal preheated combustion technology is a new clean and efficient combustion technology of pulverized coal that is being developed. It is suitable for new construction and renovation of industrial boilers, power station boilers, hot blast stoves, and kilns. It has many advantages including strong fuel adaptability, low NOx emissions, and flexible load adjustment. This paper systematically reviewed the preheated combustion technology of pulverized coal, introduced the development history of preheated combustion technology, and focused on the research and development achievements of key technologies of preheated combustion, including particle flow characteristics, preheated characteristics, combustion characteristics, NOx emissions, energy mass balance and model prediction. The progress and deployment of pilot test research and demonstration projects of preheated combustion technology were summarized, and the future development trend of preheated combustion technology was briefly discussed. This paper can provide a reference for the efficient low-NOx combustion and the development of related technical fields. ©2022 Chin.Soc.for Elec.Eng.
