Popis:	In this paper, the low load steady combustion test of a single burner was carried out on the 30MW thermal test bench of the State Key Laboratory of efficient and clean coal-fired power plant boiler. Combined with numerical simulation, the lower limit of the minimum stable combustion load of the burner was tried to find out, which provided the basic test data for the furnace combustion stability during the deep peak load regulation of the boiler. The experimental and numerical simulation results show that under 40% rated load, the outlet flame is stable and bright, and the negative pressure in the furnace is stable, which can realize the stable combustion of a single burner.
