Abstract
A gas diffuser screen surrounding a pilot burner and with one of the perforated walls of the screen slanted outwardly at an angle approximately forty-five degrees from the vertical and overlying an electrode spark igniter to ignite the gas supplied to the burner. The slanted wall forms a pocket of gas beneath the wall thereby permitting greater latitutde in placement in any direction of the electrode igniter outside the screen with respect to the pilot burner without adversely affecting the spark ignition of the gas supplied to the pilot burner.
Claims4
An ignition enhancer for pilot burners and the like, which comprises a pilot burner, means supplying gas to the pilot burner, a gas diffuser housing having a plurality of apertures in at least one wall thereof and disposed around the pilot burner, means securing the housing to a support, one of the walls of the housing having the apertures therein being slanted outwardly at an angle of approximately forty-five degrees from the vertical to confine a pocket of gas beneath the slanted wall when gas is supplied to the burner and passes through the slanted wall, an igniter electrode capable of providing a spark secured beneath the slanted wall of the housing substantially in line with the pilot burner but located within tolerance limits in any direction of plus or minus one-eighth inch with respect to the pilot burner without adversely affecting the spark ignition of gas supplied to the pilot burner.
