Abstract：Under the background of the new power system,the requirements for the deep peak shaving capacity of coal-fired power units have increased,and solving the low-load stable combustion capacity of units during the peak shaving process has become a research hotspot.Taking the low-load self-stabilizing combustion burner of pulverized coal boilers as the research object,the technical principle of the self-stabilizing combustion burner is introduced,and its combustion characteristics during low-load operation are studied.The results show that the low-load self-stabilizing burner with four combustion stabilization mechanisms,namely reverse jet,swirl,dull body and pre-combustion chamber,can achieve long-term stable combustion of pulverized coal and meet the requirements of the deep peak shaving policy.This burner has advantages in energy-saving,stable combustion at low loads,and meeting the requirements of peak shaving during start-up and shutdown as well as deep peak shaving.
