Abstract

The invention relates to a low-flow, high-mixing ratio and stepless regulation gas-liquid mixing gas generator, which comprises a round mixing channel, a spray head, an igniter and a body part. The spray head is arranged between the round mixing channel and the body part, and the opening of the spray head faces the body part; the igniter is arranged in the body part; and the round mixing channel comprises a fuel channel communicated with a fuel joint, a main air channel communicated with a main air joint, and an auxiliary air channel communicated with an auxiliary air joint. The technical problem that defects exist in the prior art is solved. The gas-liquid mixing gas generator can be reliably operated and realizes large-scale stable and high-efficiency combustion and stepless regulation.

Description

technical field [0001] The invention relates to a gas-liquid mixed gas generator. Background technique [0002] The gas generator is a device that organizes the combustion of the oxidant and fuel according to the mixing ratio required by the design to obtain the gas required by certain parameters such as pressure, temperature, flow and Mach number to achieve a specific purpose. Various countries have improved the structural design of gas generators, reduced the cost of gas generators, and determined the stable working range of gas generators through cold tests, hot tests, and simulation calculations, which have led to rapid development of gas generator technology. For example, a turbocharger test bench needs to use a gas generator to generate high-temperature gas to drive the turbine. The technical requirements and indicators of the gas generator are: 1. The fuel is alcohol, which contains C 2 h 5 The OH is 96%, and the oxidant is air; 2. The gas pressure at the outlet of ...
