Gas gas source, it is ensured that gas-cooker 2 to be measured has been in cold state spark operating condition after examination fire, presses gas-cooker 2 to be measured and has been placed on 90 °
The knob of position is struck sparks, and test starts.Since trigger sensor 5 trigger detecting first spark that ignition electrode generates
High speed camera 1 is shot, and data and image are passed to data processing equipment 4 in real time.It, can be from data after test
Reason equipment 4 obtains the igniting recorded in real time and passes fiery data and image.
Specific gas combustion range ignition passes fiery experimental method, comprising the following steps:
The igniting of gas-cooker 2 is shot using high speed camera 1, passes fiery video；
Occur at crawl since in video spark, inner ring igniting, inner ring flame stabilization, pass fire, pass fire stablize, outer circling point
Image under fire, outer ring flame stable case；
Occur visible spark image on crawl ignition electrode as there is the image of spark, crawl spark to first appear in inner ring
On image light a fire image as inner ring, crawl flame begins to change into the flame image of clear-cut surely schemes as interior ring flame
Picture, the image that Xiang Chuanhuo slot transmits grabbing flame from fire hole pass fiery image as, and crawl outer ring starts to light a fire
Preceding and flame passes completely through the picture for passing fire slot as fire is passed and stablizes image, and outer ring starts the image of igniting after grasping stability biography fire
As outer ring igniting image, the flame image that crawl outer ring is all lighted a fire and flame edge is clearly demarcated is as outer ring flame stabilization figure
Picture.
It is calculated according to the image of crawl and obtains ignition electrode sparking number, since being lighted a fire to inner ring flame stabilization inner ring
The biography fire for wearing fiery slot is passed completely through at the time of Xiang Chuanhuo slot transmits ring flame stablizes time, flame from fire hole to flame
Time lights a fire the outer ring flame stabilization time for lighting a fire stable to outer ring since outer ring；When calculating the inner ring flame stabilization time, need
By when gap sensor 3 detect the corresponding time difference data of signal and carry out COMPREHENSIVE CALCULATING.
According to calculating, the data obtained are lighted a fire, igniting property is analyzed.
Gas combustion range ignition in the utility model is passed fiery experimental provision and is fired in a very short period of time using high speed camera 1
The igniting of gas kitchen 2 passes fiery complete clear in the process and can artificially select 1-1000000 times of dynamic image slowly, and to it
It is recorded in real time, which passes fiery experimental provision and lighted a fire suitable for 2 burner of different type gas-cooker, pass fire
Dynamic experiment, for establishing the research-based research platform of gas-cooker 2.Passing fiery experimental method also with gas combustion range ignition can be from
The igniting of quantitative analysis burner on time passes time ratio shared by each stage of fiery equal segments process, to set to burner
The igniting of meter stage, the optimization for passing fiery process provide guidance.On the other hand also the igniting of different burners, biography fire can be done quantification
Assessment provides branch so that the igniting between more different gas-cookers 2 passes fiery difference for the igniting of gas-cooker 2, the improvement of igniting property
Support.
