Abstract

The invention discloses a ground gas turbine single-tube combustion chamber adopting axial gas inflow. The ground gas turbine single-tube combustion chamber comprises a combustion chamber gas inlet pipeline, a case and a combustion chamber outlet section. The upper end of the case is connected with the combustion chamber gas inlet pipeline, the lower end of the case is connected with the combustion chamber outlet section, and a flame barrel is mounted on the combustion chamber outlet section. The flame barrel is connected with the combustion chamber gas inlet pipeline through a natural gas inlet pipeline; a natural gas nozzle, a first-level hydrocyclone assembly and a second-level hydrocyclone assembly are mounted at the top end of the head of the flame barrel, and the natural gas nozzle is sleeved with the first-level hydrocyclone assembly and the second-level hydrocyclone assembly. A plurality of natural gas injection holes are formed in the natural gas nozzle; a main combustion hole is formed in the upper side of the middle section of the flame barrel, and an igniter mounting assembly is arranged at the upper end of the main combustion hole; a mixing hole is formed in the lower side of the middle section of the flame barrel. The invention further discloses internal structures of the hydrocyclone assemblies. According to the combustion chamber, fuel and air can be mixed fast and evenly, a stable reflux area is formed at the head of the flame barrel, and the overall service life of the combustion chamber is prolonged.

Description

technical field [0001] The invention belongs to the field of ground gas turbines, and in particular relates to a single-pipe combustion chamber of the ground gas turbine with axial air intake. Background technique [0002] In the past ten years, the use value and application prospects of ground gas turbines have been fully proved by scholars at home and abroad. And with the increasing energy consumption, distributed power has gradually gained attention. Distributed power supply does not require long-distance power transmission and distribution equipment, can use energy nearby, and can conveniently realize heat, electricity, and cooling triple production according to user requirements, and has the advantages of being able to meet the power and electricity requirements of special application environments. The ground gas turbine is one of the most fast, stable and convenient energy conversion devices with high power density to convert the chemical energy of fuel into electrica...
