The invention provides a reverse flow combustor allowing a wider range of stable running. The reverse flow combustor comprises a diffuser, a combustor casing, a flame cylinder head end wall, a flame cylinder outer wall, a flame cylinder inner wall, a large elbow and a head atomizer. Air enters the combustor through the diffuser; part of the air enters a flame cylinder through the head atomizer; another part of the air enters through a main combustion hole of the flame cylinder and a mixing hole thereof, the remaining enters from a cooling structure. The air and fuel fully mix and combust in the flame cylinder. After passing by two 180-degree turns, the air leaves the combustor. The head atomizer performs atomizing in a mixed mode of pressure centrifugal atomizing and pre-swirling prior to pre-film air atomizing; the fuel is fed through a main oil circuit and an auxiliary oil circuit; the main combustion hole arranged in the outer wall of the flame cylinder and the mixing hole thereof are provided with a hood, jets are avoided flowing to the head, and inner and outer jets are ensured being symmetrical. The range of stable running of the reverse flow combustor can be expanded, and uniformity of fuel gas temperature of an outlet is guaranteed.
