Method and device for researching combustion phenomenon of distributor of combustion gas water heater

Abstract

The invention discloses a method for researching a combustion phenomenon of a distributor of a combustion gas water heater. The method can achieve quantitative detection of influence of primary and secondary air ratio on flame by the following steps: independently supplying the primary air and the secondary air of the distributor of the combustion gas water heater; adjusting the external air speed, the air inlet pressure, the size and distance of nozzles, and the distance between the nozzles and an air inlet of the distributor; recording the height and width of inner flame and outer flame of the flame, and the periodical rule of flame oscillation. The method uses 1200-degree-high-temperature-resistant quartz glass as a combustion internal cavity so as to directly observe the flame combustion situation. The invention also discloses a device for researching the combustion phenomenon of the distributor of the combustion gas water heater. The method and device can research the height and the width of the inner flame and outer flame of the flame, and the periodical rule of flame oscillation by observing the external air speed, the air inlet pressure, the size and distance of nozzles, and the distance between the nozzles and an air inlet of the distributor.

Description

technical field [0001] The invention relates to the technical field of detection and analysis of gas water heaters, in particular to a method and device for analyzing the combustion phenomenon of a gas water heater sub-flame. Background technique [0002] At present, there are many distributors of gas water heaters in the gas water heater market, with different structural sizes. In addition to testing their performance when installed on the whole machine, there is still a lack of parameters to evaluate the performance of distributors. For distributors at different external wind speeds, No one has considered the influence of air intake pressure, nozzle size distance, distance from nozzle to the air inlet of the firearm on the height, width and oscillation period of the flame inside and outside the flame, and there are very few devices that study its independent combustion performance at the same time. , so the same method and device for studying the combustion phenomenon of t...
