Method and device for testing gas combustion nozzle

Abstract

The invention discloses a method and a device for testing a gas combustion nozzle. The method is characterized in that a combustible gas and high-pressure air are connected into a nozzle to be tested, so as to generate a vortex saturated mixed gas in the nozzle, the mixed gas combusts when meeting an electric spark generated by a pulse igniter so that a torch is formed, the color, the length and the shape of the flame are observed, and the highest temperature of the flame and the content of harmful gases exhausted to air are detected by using a sensor so that a design basis is provided for the application of the combustion nozzle. According to the method and the device, the pollution of the various harmful gases to the environment can be reduced when the existing energy resources are maximally utilized; the device has the function of objectively evaluating the structure design of the nozzle in the detection of combustion nozzles with different fuels as combustion mediums and different structures, and is good in popularization and application values, and the optimal air-fuel ratio of various kinds of nozzles or a certain nozzle can be found.

Description

Technical field [0001] The invention relates to the technical field of combustible gas nozzle testing equipment, and is a testing method and device for detecting and adjusting the combustion state of the nozzle and the emission of harmful gas. Background technique [0002] Under the guidance of the national policy of focusing on the development of energy-saving and emission-reducing products, the full combustion of combustible gas occupies an extremely important position. While maximizing the use of existing energy, it can reduce the environmental pollution of various harmful gases. At present, combustible gas heating is widely used in various fields such as building materials, machinery, food processing, and material molding. Combustion nozzles with different fuels as combustion media and different structures should come out on demand. However, testing devices for evaluating the advantages and disadvantages of nozzle design and looking for The equipment with the best air-fuel ra...
