I do appreciate your efforts to make it easy and simple to understand, this is one of the best videos I have watched on this topic. please continue on doing videos with that high quality, many thanks.
For furnace the Draft motor speed is fix i.e. air input is fix, now to get the maximum heat out with minimum gas input (max efficiency) adjustment (air & fuel ratio) for the fix burners profile study is important.
hi, im from colombia, thanks for this video, could you tell me if this combustion chart for natural gas work to every sistems, i mean, im working now with gas engines and i will try to understand that, so, i dont know, maybe you can talk to me about it. Best regards, oh, im mechanical engineer.
HI Luis: This chart should work for all natural gas systems including gas engines. I talked with an industrial gas fitter that I work with. He said that the only thing that might change the chart is any variables that might be added in the systems you work with. If you have more questions pass them on to me and I'll see what I can find out. Thanks for watching!
@@tradestutor1191 Thanks. I just don't understand what can happen to the engine (temperature, valves...) if you go too far away from the 0% excess, to the lean side (excess in oxygen).
@@byAnArgentinian Ya, I'm not sure either. That would be a good thing to look up though as the more you understand the chemistry of combustion the more efficient you can get. And the more you understand combustion efficiency the more interesting gas appliances and anything else that runs on fuel can become.
