Abstract

A furnace firing system including a furnace port, a burner including a nozzle at one end received in the port and a mounting for the burner to position the nozzle in the port at a desired firing angle. The burner comprises an elongated body having a frustoconical locating member fixedly mounted therearound adjacent the other end of the burner and tapering towards the one end. The mounting is connected to the burner solely at the locating members via a receiving member having the inner surface thereof configured to closely receive the locating member. The locating member is releasably retained in the receiving member and the burner is pivoted about a pivot axis disposed between the locating member and the nozzle and substantially adjacent the nozzle by a pivot arm extending between the pivot axis and the receiving member and connected to the receiving member at one end. A base and a mounting member connected to the base at one end and pivotally connected at its other end to the other end of the pivot arm at the pivot axis, enable the pivot arm to pivot about the pivot axis with respect to the mounting member.
