Okay, heat and color wavelength and temperature etc is NOT my cup o tea, that's more for Physicist, Mechanical and Thermodynamics Engineers, but heres a "belief" I have which I hope some Mechanical or Thermo Engineer or Technician or Billy Bob or heck anybody can shoot down or reinforce?
We always hear about (and I agree) how its desirable that an ignition spark be bright visible BLUE versus a thin wimpy lookin YELLOW. Ima thinkin that's because its in part HEAT (Like a fire or a spark) that ignites the fuel air mixture and the BLUE spark is physically hotter in temperature then the YELLOW spark. If you think about it when you adjust a gas appliance its done so you get the nice BLUE flame (correct mix of air and fuel) versus the YELLOW flame (incomplete combustion, fuel to air ratio isn't right or something to do with all that???)
Soooooo is the BLUE spark physically hotter in temperature then the YELLOW spark??
If you notice if youre testing an ignition wire if the gap is close the spark is blue, but as you pull the wire further away it changes to a thin yellow. As I explained below the spark is of a fixed X energy which is Volts X Amps X Time so if voltage increases (due to wider gap) current and/or arc time duration decreases and so does the spark color!!!!!!!
Does BLUE represent higher physical temperature then then YELLOW????????????????????????? When I heat metal with my torch it eventually gets red then maybe towards white......
