The invention relates to a low-nitrogen-emission combustion chamber and a gas turbine including the combustion chamber. The combustion chamber comprises a combustion chamber head part and a combustion chamber cylinder connected up and down; the combustion chamber head part includes a secondary gas mechanism, a main gas mechanism encircled at the external of the secondary gas mechanism, and an air inlet formed above the secondary gas mechanism and the main gas mechanism; the combustion chamber cylinder includes an inner flame cylinder for respectively communicating with the secondary gas mechanism, the main gas mechanism and the air inlet, and an outer flame cylinder encircled at the external of the inner flame cylinder and communicating with the air inlet; and a combustion chamber outlet is formed in the bottom of the inner flame cylinder. Compared with the prior art, the combustion chamber can prominently reduce the nitrogen oxide emission of a micro gas turbine combustion chamber, improves the combustion efficiency, and realizes wide-load, low-emission and high-efficiency stable operation under 40-100%; and the gas flows in a main gas pipe and a secondary gas pipe are adjusted, so that the simple cycle and the bring-back thermal cycle can be flexibly converted, and the economy is excellent.
