Abstract

The invention relates to the technical field of combustion chambers of Stirling engines, and discloses a dual-mode combustion chamber of a Stirling engine, and an implementation method of the dual-mode combustion chamber. The dual-mode combustion chamber of the Stirling engine comprises a hollow combustion chamber shell body, and a dual-mode combustor which is arranged at the end, away from the machine body, in the combustion chamber shell body, wherein the end, away from the machine body, of the dual-mode combustor penetrates through the combustion chamber shell body, and the dual-mode combustor is used for carrying out a high-pressure pure oxygen combustion mode or a low-pressure air combustion mode. The dual-mode combustion chamber of the Stirling engine further comprises a gas flow guide ring. The dual-mode combustion chamber of the Stirling engine further comprises an air flow guide ring. The dual-mode combustion chamber of the Stirling engine further comprises a heat exchanger, wherein one end of the heat exchanger is arranged in the combustion chamber shell body, and the other end of the heat exchanger is connected with the machine body. The flexibility of the working occasions of the Stirling engine can be improved through dual-mode combustion of the Stirling engine, use in different working occasions can be achieved only through one Stirling engine, a power system canbe simplified, and the power density of the power system is increased.

Description

technical field [0001] The invention relates to the technical field of a Stirling engine combustion chamber, in particular to a Stirling engine dual-mode combustion chamber and an implementation method thereof. Background technique [0002] The Stirling engine is a piston engine with external combustion. Its combustion method is continuous and steady. Therefore, its combustion chamber has high flexibility, that is, the Stirling engine combustion chamber pressure can be adjusted in a wide range, and different fuels and fuels can be used. oxidant, while the structure of the Stirling engine is basically unchanged. According to the different combustion pressure and oxidant, the Stirling engine combustor can generally be divided into a high-pressure pure oxygen combustor and a low-pressure air combustor. [0003] The current Stirling engine combustor is either a high-pressure pure oxygen combustion mode or a low-pressure air combustion mode. In different working situations, Stir...
