The invention relates to the technical field of gas turbines, and particularly to a micro gas turbine and a combustion chamber thereof. The combustion chamber comprises a shell, a flame tube, a fuel spray nozzle and a fuel pipe, wherein the fuel spray nozzle communicates with the fuel pipe; the shell comprises a casing and an air inlet pipe; the casing is arranged on the peripheral side of the flame tube in a sleeving manner, and a ring cavity is formed between the casing and the flame tube; the air inlet pipe comprises an air inlet and an air outlet, and the air inlet communicates with the air outlet; and the end, close to the fuel spray nozzle, of the ring cavity communicates with the air outlet of the air inlet pipe in the axial direction of the flame tube. The micro gas turbine and thecombustion chamber thereof have the benefits as follows: the air intake is uniform, and the problem that the conventional combustion chamber is nonuniform in fuel gas temperature at the outlet due tolocal high temperature is
