Abstract

The invention discloses a flat-flamed burner. The flat-flamed burner comprises such modules as a stove plate (1), a pre-mixing air chamber (2), a protective air chamber (3), an experimental chamber (4), an air exhaust cap (5), a pressure regulator (6), observation window glass (9), a glass sealing cover (10), and the like. The flat-flamed burner is a modularization flat-flamed burner which is compact in structure, convenient in operation, high in safety and reliability, convenient to maintain after the improvement, capable of reducing photometric errors, self-adjustable in pressure and more stable in the generated flat flame. Different modules are designed, and then assembled to a burner of different functions, so that the modularization design method can constantly expand the application range of the flat-flamed burner.

Description

technical field [0001] The invention relates to a burner, in particular to a self-adjustable pressure modularized plane flame burner suitable for the technical field of optical combustion diagnosis. Background technique [0002] Combustion diagnosis using optical measurement technology is the main method to study the combustion mechanism at present, and the combustion diagnosis experimental system is an important factor affecting the experimental process and results. The planar flame burner is used to generate a planar flame. As an instrument and equipment for combustion diagnosis experiments, its design and manufacturing level will directly affect the efficiency of scientific research and the accuracy of experiments. [0003] The most widely used flat flame burner is the McKenna flame furnace, which is used in the document "Laser Diagnostics Of Trace Species In Low-Pressure Flat Flame" ("Progress in Energy and Combustion Science" Vol.352009 Page: 365-382) McKenan flame fur...
