摘要:
The present invention relates to an ignition device for boilers or the like comprising a pair of electrodes (1,2) made of conductive material housed within a covering body (13,23) made of insulating material and connected to high voltage electric pulse generating means. There are provided supporting means for supporting the pair of electrodes, which are composed of means housing electric pulse generating means. Moroever the electrodes housed inside the insulating covering body are directly connected by one of their ends (12,22) to the electric pulse generating means, preferably without interruption. According to a particular embodiment the device of the present invention allows the high voltage circuit to be completely galvanically isolated for triggering the spark between the two electrodes and the low voltage power supply circuit, both the electrodes being connected to the electric pulse generating means.

The present invention relates to a method for fixing igniters for boilers or the like, which method includes insertion of said igniter into a hole for receiving the ceramic body of the igniter, which receiving hole is formed in a wall or fixing plate and is of such a size as to form a gap area of predetermined size between the outer surface of said ceramic body of the igniter and the inner surface of said receiving hole, when the igniter is inserted in the hole, means for fixing and sealing the igniter to said fixing plate being provided in said gap area. Said fixing and sealing means consist of a glassy material that is previously converted to the liquid or semiliquid phase to ensure mechanical adhesion and/or physico-chemical bonding to the outer surface of said ceramic body of the igniter and the inner surface of said receiving hole and later converted to the solid phase. The present invention further relates to a device obtained by said method.
