Hot bulb ignition head for a device for firing rough ceramics, particularly bricks

A hot bulb ignition head adapted for receiving therein a solid fuel, comprising:

• an elongate hollow body member of finite length and defining a central chamber therein;
• an elongate hollow connecting conduit connected to one end of said hollow body member and for the intermittent delivery of solid fuel by compressed air, the interior of said connecting conduit being in open communication with said central chamber, said hollow body member having a larger diameter than said connecting conduit;
• a pair of side plates oppositely disposed in said hollow body member and secured to the interior wall of said hollow body member along lateral edges thereof extending coextensively with the longitudinal axis of said hollow body member, said side plates extending beyond the other end of said hollow body member remote from said connecting conduit, the terminal ends of said side plates terminating externally of said hollow body member, each said side plate between said lateral edges thereof being spaced from said interior wall of said hollow body member to define a back-pressure chamber which opens outwardly of said hollow body member at said other end;
• and
• a baffle plate secured to and extending between the terminal ends of said side plates located externally of said hollow body member, the mutually adjacent edges of said baffle plate, said side plates and said hollow body member defining oppositely and radially facing first openings between said central chamber and the exterior of said hollow body member.
