Thanks Darren, always good! You are truly a help to the world! Your point about "Black smoke" is usually CARBON burning is helpful. I have done just about everything that you have ever suggested, cleaned out both the tubes and the orifices, adjusted the flame, etc. and still get a "POW" when it starts up and it still burns black smoke. Could it have anything to do with the the main regulator where the tanks are hooked up?
As he stated check your pressure first as RV regulators are not the best, if all your appliances are sooting this will likely be the problem. If its just one appliance that's sooting first clean the main burner orifice with compressed air only, then open up the primary air adjustment to the point you have a blue flame on the burner where its not lifting of the burner, if you have the primary air all the way open and no blue flame there will be something inside the burner Venturi that is not allowing the air and propane to mix properly prior to the burner tip. At this point it's a good idea to remove the burner to check the Venturi and blow out the holes in the burners that will collect lint and dust sucked in by the vacuum created by the Venturi. Soot is generally created by lack of oxygen mixing with the gas prior to combustion and this is only exasperated at higher elevations as there is less oxygen in the air up there.
Furnaces don't just output CO2 they also output CO, HC and NO depending on the air-fuel ratio. Industrial furnaces. IC engines and boilers have catalytic converters on them. I tune them to 6000ppm CO and 700ppm NO. Post catalytic converter is 72ppm CO and 1 ppm NO. I set the gas pressure using the regulator just like on an RV. For high elevation you can re-jet it or lower the fuel pressure.
I live in metro Atlanta and filled my propane tank there. I traveled to South Rim of grand canyon. All of my propane appliances had poor performance and soot. Is there such a thing as "altitude blend"? We are traveling west next year and it would help if I knew how to better prepare. BTW once we were at lower altitudes, things worked better and no noticeable soot!
I'm so glad you're still making videos keep up the good work! You've helped restore my 91 jayco 180rb
