Abstract:
An ignitor assembly for a fossil fuel-fired combustion furnace, comprising:an electrode rod; an elongate housing for supporting therewithin the electrode rod, the elongate housing having an opening at one axial end for receiving therethrough an electrical source connector which is operable to supply electrical current from an electrical source; means for electrically interconnecting the electrode rod and an electrical source connector to one another, the electrically interconnecting means being operable to establish electrical communication between the electrode rod and the electrical source connector when the electrode rod and the electrical source connector are disposed at respective predetermined positions relative to one another forming a communication interface through which electrical current flows between the electrode rod and the electrical source connector, the means for electrically interconnecting including means for fixedly securing the electrical source connector thereto at a location to one side of the communication interface; and biasing means acting on the means for electrically interconnecting at a location thereon on the other side of the communication interface at a spacing from the communication interface to bias the means for electrically interconnecting in a direction from the electrical source connector toward the electrode rod connector, the electrical source connector being movable against the bias of the biasing means, as a result of which the respective predetermined positions of the electrode rod and the electrical source connector relative to one another change and, consequently, the position of the communication interface changes, and the electrical source and the electrode rod being in overlapping relationship with one another such that the electrical contact between the electrical source and the electrode rod continues throughout the range of positions to which the communication interface moves as a consequence of the movement of the electrical source against the bias of the biasing means.
