Description
Technical field
This utility model is related to a kind of burner, especially relates to a kind of civilian burner assay device.
Background technology
The operation principle of most of civilian burners (atmospheric burner) is as follows：Combustion gas under a certain pressure, with certain
Flow velocity flows out from nozzle, enters air-breathing collapsible tube, and combustion gas is leaned on the energy of itself to suck primary air and (sucked a part in advance empty
Gas), in injector, combustion gas and primary air mixing, then, flow out through head fire hole, the auxiliary air mixing of air-flow periphery
(during burning, having fed portion of air again), is burnt, and forms flame of originally lighting a fire.Typically, atmospheric burner is once empty
Gas factor alpha ' it is 0.45-0.75.When primary air ratio α '=0, belong to diffusion type burning.As primary air ratio α>When 1,
Belong to fully premixed burning.
Civilian burner includes injector and burner head two parts, and wherein, injector part has included tune wind
Plate, primary air mouth, injector throat, nozzle, burner head part includes fire hole.Nozzle in injector determines fire
The size of power (thermic load or power), back pressure in air regulating board, primary air mouth size, induction tunnel parameter and cavity etc. determines
The number of primary air.Thus, when existing civilian burner carries out efficiency test, flue gas (waste gas) emission testing, in order to reach
To preferably trystate, need constantly to adjust nozzle orifice size, air regulating board, primary air mouth and induction tunnel parameter etc..Adjustment
Parameter more, and need make several samples constantly to change, be so easily caused test interference factor increase, impact
The credibility of power result of the test.
Shown in the trystate figure of existing civilian burner as shown in Figure 1, nozzle determines gas flow and (determines combustion gas
After species, flow is directly proportional to thermic load), the cooperation between induction tunnel and nozzle determines the flow of injection air.Tested
When it is thus necessary to determine that combustion conditions, that is, whether gas flow and flame status during air different ratio after-combustion good.But adjusting
When whole gas flow and air stoichiometry, adjustment is relatively complicated, and is not very accurate.When such as adjusting gas flow, need to change
The nozzle of different pore size.Need to change induction tunnel parameter during adjustment air mass flow, test again after installation.And demarcate combustion gas and sky
The gas proportioning cycle between the two is also longer.
Fig. 2 show the design cycle of existing general burner, when carrying out civilian burner test, adjustment burner conversion
When thermic load, operating mode, efficiency, all need progressively to adjust nozzle bore parameter, injection pipe size, air door size, fire cover fire hole strong
Distribution form of degree, fire hole angle or fire hole etc., has considerable influence to the concordance and test period of test.
