Auto ignition temp of natural gas

Auto ignition temp of natural gas

Auto ignition temp of natural gas

(OP)
In Australia our gas codes allows burners to be fired into a chamber which has reached a minimum temperature of 750degC (1382degF), without flame monitoring. This being well above the auto-ignition temp of nat gas which is just under 500degC. Other gases like propane being slightly less.

Additional requirements are that the chamber has to hold temperature above 750degC for 1 hour if the burners are turned off.

Is 750degC the minimum requirement in the USA and Europe?

Thanks,

I meant just under 600degC for the auto ignition temp of nat gas.
