Visualized high temperature and high pressure combustion device

Abstract

The invention discloses a visualized high temperature and high pressure combustion device which comprises an incendiary bomb body, a glass assembly body, a high temperature switching section, a constant voltage switching section and a cooling copper pipe. The high temperature switching section and the constant voltage switching section are used together, and the pressure of a main combustion chamber is shared on two ways of glass. The use temperature of the glass is reduced. The maximum use pressure of the combustion device and the visualized window area are improved. According to the invention, the modular design of an optical window is used; the demolition frequency and the installation time of the optical glass are reduced; the service life of the optical glass is effectively improved; the replacement frequency of a sealing gasket is reduced; all sealing parts are non-cooled sealing; the construction is simple; the processing and installation are convenient; continuous testing under high temperature and high pressure conditions are realized; engine combustion and exhaust gas recirculation processes can be simulated, and visualized research is carried out; and a schlieren method, a laser absorption and scattering method, laser induced fluorescence and other test methods are carried out on air-fuel mixture, evaporation, combustion, soot generation and the like.

Description

technical field [0001] The invention relates to the field of high-pressure combustion research, in particular to a visualized high-temperature and high-pressure combustion device. Background technique [0002] Research on engines with wide fuel source, high efficiency, low pollution, low noise and easy maintenance is of great significance for energy saving, emission reduction and environmental protection. In order to fully explore the combustion potential of the engine and study its exhaust gas recirculation and other processes, a visual combustion device is essential. At present, the combustion spray experimental devices developed by laboratories and research institutes in various countries mainly include: fast compressors, constant pressure flow combustion devices, preheating type constant volume bombs, precombustion type constant volume bombs, and optical engines; however, although there are There are many documents and patents on constant volume bombs and optical engine...
