Oxy pilot spark ignition gas fire

TonyW2 · 11 Nov 2010

Open coal effect gas fire.
Ignition sparks OK but pilot does not light.
Spark jumps to tip of thermocouple.
However, Pilot ignites OK with a match and does not extinguish.
Jets blue & play onto thermocouple OK
Pilot jets all blown through.
Electrode gap about 4mm. (Have tried varying this)
Main jets operate without problems.

Any suggestion, please.
(Not a safety issue, just inconvenient.

Should'nt be jumping to the thermo

Put something that smokes (incense) near the pilot outlet - does the smoke drift away from the ignition point? A flame behaves differently than a gas jet.

Schoolboy physics. Why do you think a flame stays as a flame? And yet smoke dissipates? You need a basic grip of chaos theory and Heisenberg's uncertainty principle to get the gist of it. I aint got time to educate you. Sorry.

Ah yes.......Heisenberg

'In quantum mechanics, the Heisenberg uncertainty principle states by precise inequalities that certain pairs of physical properties, such as position and momentum, cannot be simultaneously known to arbitrarily high precision. That is, the more precisely one property is measured, the less precisely the other can be measured. The principle states that a minimum exists for the product of the uncertainties in these properties that is equal to or greater than one half of the reduced Planck constant (ħ = h/2&#960

.'

My personal guess is the bloody spark gen is arcing......but what do i know.

Check the lead from the spark gen to the electrode....they can leak to earth on occasion.

na i think joe was right john

What libby said.Spark should be jumping to the tip of the pilot burner.

Thanks for assistance.
Really useful forum this, as that is the first time I have seen such a lucid explanation of Heisenberg.
