Ignition system for post-mixed burner.

摘要

Post-mixed burner apparatus capable of igniting a combustible gas mixture of fuel and oxidant discharged from the burner comprising: a first passage means for supplying fuel gas and a second passage means for supplying oxidant gas, both of said passage means (1, 2) terminating at the discharge end (4) of the apparatus. An igniting system consisting of the two electrically conductive passage means (1, 2). The second passage means being spaced from the first passage means such that the breakdown voltage between the both passage means (1, 2) is lowest at the discharge end (4) of the apparatus, whereby the electrical discharge occurs only across the space between the both passage means (1, 2) at the discharge end (4).
