Embodiment 1

[0106] [Example 1] Rotary impeller type

[0107] Its structure is as Figure 3-5 As shown, it consists of a wheel shell, a wheel disc, and blades. The wheel shell constitutes the outer wall space, and the telescopic blades are arranged on the wheel disc to form the rotor to rotate in the inner space of the wheel shell. The wheel shell, the wheel disc and the blades mutually constitute air intake, combustion and exhaust spaces. The round of the wheel shell can be divided into two or more groups based on the three intervals of air intake, combustion, and exhaust according to the needs of function and structure, so as to realize the functions of air intake, combustion, and exhaust of the combustion chamber. The intake space is connected with the exhaust pipe of the compressor, and is equipped with a fuel injector, which injects and atomizes fuel into the intake space to form a combustible mixture. A spark plug is installed in the combustion space to ignite the mixed gas in goo...

Embodiment 2

[0114] [Example 2] Rotating star wheel type

[0115] Such as Figure 6 shown. The rotating star wheel type constant volume combustion chamber is mainly composed of a wheel housing, a star wheel and an exhaust baffle. The wheel housing is an annular space containing a rotatable star wheel. In the middle of the star wheel is a groove (that is, an arc-shaped transition section), and on both sides are radial teeth (that is, blades). The wheel housing is divided into two or more groups of air intake, combustion, and exhaust spaces. The star teeth of the star wheel cooperate with other structures to complete the three processes of air intake, combustion, and exhaust. The intake chamber is connected with the exhaust pipe of the compressor and equipped with a fuel sprayer. A spark plug is installed in the combustion chamber, and the exhaust chamber is connected with the intake pipe of the turbine. During the exhaust process, all the gas enters the turbine through the exhaust baffle...

Abstract

The invention belongs to the field of gas turbines and discloses a constant volume combustion chamber and a constant volume combustion gas turbine. The equal-volume combustion chamber includes: a housing, a disc, blades, guide grooves and at least one equal-volume combustion unit; the disc and multiple blades are arranged inside the housing; the disc has a guide groove, and the vanes are arranged along the radial direction of the disc It is telescopically arranged in the corresponding guide groove; the adjacent blades are sealed and matched with the inner wall of the shell and the outer peripheral surface of the wheel to form a combustion chamber; The combustion space and the exhaust space; the air intake space is provided with an air inlet, and the exhaust space is provided with an exhaust port; the part of the circumferential inner wall of the shell located in the air intake space gradually expands and transitions along the rotation direction of the wheel, and is located at The part in the exhaust space tapers and transitions along the rotation direction of the wheel disc, and the part in the constant volume combustion space forms a concentric circle with the outer peripheral surface of the wheel disc. Compared with isobaric combustion, the invention has higher efficiency, lighter weight and wider application range.

Description

technical field [0001] The invention belongs to the field of gas turbines, and more specifically relates to a constant volume combustion chamber and a constant volume combustion gas turbine. Background technique [0002] From the advent of the gas turbine to the present, the circulation heating method is the isobaric combustion method. The mechanism for realizing the combustion of this combustion method is relatively simple, such as cylinder type and annular tube type, which are easy to realize. And the flow is continuous, suitable for large flow and high power engines. But its cycle thermal efficiency is low. The thermal efficiency of a simple cycle can only reach 20-40%. The thermal efficiency is higher when used in aviation, and the efficiency is lower when used on land and sea. The thermal efficiency of the combined cycle with steam thermodynamic power mechanism is higher, which can reach 52-60%. It is related to the combustion temperature. For example, when the initi...
