The invention relates to the field of fuel oil burners, and provides combustion test equipment. The equipment comprises an outer barrel and an inner barrel, wherein the inner barrel is arranged in the outer barrel; an annular air inlet cavity is formed through limitation of the inner barrel and the outer barrel; a flame which is mainly distributed at the center of the inner barrel is formed through a first-stage oil injection tube and a first-stage air inlet pipe arranged at an air inlet end of the inner barrel; the annular air inlet cavity communicates with the air inlet end of the inner barrel, so that a gas ejected from a second-stage air inlet pipe in the annular air inlet cavity flows downwards along the outer wall of the inner barrel and enters the inner barrel; in addition, through diversion action of an annular channel formed between the first-stage air inlet pipe and the air inlet end of the inner barrel, airflow flows upwards along the inner wall of the inner barrel and is finally mixed with fuel ejected from a second-stage oil injection pipe for combusting, the flame can be formed in the edge area of the inner barrel, and the airflow is heated by the inner barrel, so that sufficient combustion of the fuel ejected from the second-stage oil injection pipe can be kept, and the uniformly distributed flame is formed at an exhaust end of the outer barrel.
