Gas enters channel and auxiliary air enters on channel and is disposed with air blower, flowmeter, pressure measuring machine, and combustion gas enters channel successively
Flowmeter, pressure measuring machine are set, and transparent housing, the periphery setting camera of transparent housing is arranged in distributor in testing stand.
As a further illustration of the above scheme, the testing stand includes a bracket, transparent housing setting on bracket, thoroughly
There are two bolts for setting on bright outer cover, and distributor is arranged in the seal chamber being made of transparent housing, and is fixed on bolt,
Primary air above the distributor bottom, bracket enters channel and auxiliary air enters above channel that be additionally provided with can be removable
The dynamic platform that keeps out the wind, is arranged shifting chute on bracket, and the removable platform that keeps out the wind is arranged on bracket, and removable keep out the wind also sets between platform and distributor
It is equipped with fixed baffle.
Further, the primary air enters channel and is arranged in testing stand side, and auxiliary air enters channel setting and exists
Testing stand bottom.
The transparent housing is high temperature resistant quartz glass.
Compared with prior art, the method and dress for the research gas heater distributor combustion phenomena that the invention patent provides
It sets and has the advantages that
The present invention of the above method and device is used to provide one kind for gas heater internal flame combustion phenomena research
Useful device effectively analyzes the factor of each influence flame height, intensity, to optimization distributor structure, reasonable disposition one or two
Air register reduces combustion chamber cavity heights, and reasonably selects the wind speed offer foundation of fume exhaust system.
