How to conduct an oil gun atomization test
Thread Content
The 75t/h circulating fluidized bed system that we are studying now uses natural gas for ignition beneath the bed, but the 240t/h circulating fluidized bed system that we will be operating in practice will use fuel for ignition beneath the bed. Therefore, I would like to ask everyone how to conduct atomization tests on fuel nozzles. Thank you all. This post was last edited by eddy-8280103 on 2009-2-22 at 19:03.]
It seems that there are specialized cold-test equipment for burners, which can produce photos magnified by several hundred times, allowing one to see the particle size after atomization (I haven’t seen the actual process; only the final photos).
**Relevant standards have been issued, something related to special equipment; you can look them up by yourself.
It seems that the manufacturer of the oil gun provides the data and the methods for doing this; we haven’t conducted this experiment ourselves. In the past, we simply followed the operating procedures to ignite it! !
I wonder what those parameters are for the oil gun you want to make? 1. If only force is applied, it can be done directly on the stove. A flow meter is installed on the fuel main pipe; during the boiler startup process, the fuel pressure before the furnace is adjusted, fuel is supplied for combustion, and the fuel flow rate is recorded over a certain period of time, allowing the output capacity of the fuel injector to be calculated. 2. To determine performance parameters of oil guns such as the atomization angle, atomization particle size, and dispersion degree, a specialized testing bench is required. I can introduce one to you: the Department of Thermal Power Engineering at the former Shanghai University of Machinery had experimental benches; you can contact Professor Ma Qiliang.
Remove the oil gun and conduct a manual test to check its atomization effect!
I know the method for testing the atomization of the oil gun during debugging: gradually increase the oil pressure in the oil gun and observe its atomization level. This method is simple to use, requires minimal effort, and has low testing costs; however, its accuracy is not high, as the atomization pressure of the oil tends to be too high. This simple approach is generally used for debugging small-scale units.
