Energy and environment are the two major themes of today's social development. Self-preheating combustion technology has opened a new path for the directional transformation of coal nitrogen, achieved the inhibition of NOx generation in the combustion in-situ reaction, better realized the organic integration of efficient combustion of pulverized coal and low NOx emission, and showed stronger advantages in the denitration efficiency, environmental compatibility and investment and operation cost. This study first introduces the basic principle of self-preheating combustion technology, including the principles of self-preheating, the principles of preheated fuel combustion and the NOx formation mechanism. Subsequently, the research progress in reducing NOx emission by self-preheating combustion technology in 30 kW bench scale text rigs and MW grade pilot-scale text rigs, and the industrial application of self-preheating combustion technology are respectively illustrated. Finally, the corresponding conclusions are given, and the future development direction of self-preheating combustion technology is prospected.
