Abstract

A rotational flow water film cooling type combustion chamber comprises a chamber wall, a flame tube head and two hydrocyclones, wherein the flame tube head is mounted in an inner cavity of a combustion chamber body, and the two hydrocyclones enable water input externally to form a rotating water film attached to the inner surface of the chamber wall. The flame tube head is provided with a premixing chamber. The hydrocyclones are located behind the flame tube head and spaced from the flame tube head. Each hydrocyclone is composed of a barrel, spray heads, mounting bases and swirl blades, wherein the outer surface of the barrel and the inner surface of the chamber wall define an annular water cavity, one end of the annular water cavity is closed, and the other end of the annular water cavity is open; the swirl blades are mounted at the open end of the annular water cavity; the number of the spray heads is 2-4, the number of the mounting bases is the same as that of the spray heads, the spray heads are mounted on the chamber wall through the mounting bases, water inlet holes of the spray heads are communicated with the annular water cavity, and the axes of all the spray heads are located in the tangential direction of the chamber wall.

Description

technical field [0001] The invention relates to the technical field of cooling of a high-temperature combustion chamber, in particular to a newly created swirl water film cooling type combustion chamber. Background technique [0002] The combustion chamber usually adopts the method of film cooling, but for the combustion chamber that requires all the air in the combustion chamber to be burned, and the exhaust gas does not allow oxygen, as well as the high-temperature combustion chamber, the film cooling is not suitable because there is no Excess air is used for film cooling, and the outlet temperature of the high-temperature combustion chamber is very high (taking natural gas as an example, the outlet temperature of the combustion chamber can reach 2050°C), and the use of film cooling cannot effectively protect the chamber wall from being burned. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and pro...
