Let us measure by inserting the thermocouple in the flame,
that is, by exposing it to multiple gas jets.

The 150 gasifier has 80 gas jets.
In combination, they have to produce temperatures higher than 600 C.
Too much secondary air could have a cooling effect.
But if the secondary air is hot as it enters the burner and if there is not
too much of it,
should there not be a relatively high flame temperature from such a blue
flame?

Thanks.
