ABSTRACT:
An igniter for igniting waste gas discharged from a gas discharge pipe has a flame detection circuit. The igniter has an electrode and a gas conduit which supplies a source of fuel to the nozzle for creating a flame to discharge across the gas discharge pipe. A continuous DC voltage is supplied to the electrode, with any current flow between the electrode and the housing indicating the presence of a flame. Passages are provided near the electrode for circulating hot gas to reduce moisture, which could provide false readings. The internal components are mounted on a frame, which is secured in place by a locking device located at the bottom of the housing. The nozzle has a plurality of slots for the discharge of flame with the slots located at the lower end of the nozzle being of larger surface area than at the other end of the nozzle. Auxillary lines extend through the housing for discharging low volume waste gas and flame extinguishing fluid, if desired.
