ABSTRACT:
A pilot flame sensing system employs an electromagnetic transducer (41) at the bottom of a vertical stack (11) used for burning waste gases which incorporates a pilot burner (15) at the top of the stack (11). The electromagnetic transducer (41) responds to acoustic energy generated by the pilot burner (15) and communicates down thorough an igniter tube (21) extending essentially the full height of the stack. At least one diaphragm (43) having a low loss tangent and high modulus is used to suspend the electromagnetic transducer (41) so as to allow the electromagnetic transducer (41) to resonate the diaphragm (43) thus improving a signal to noise ratio of an output signal of the electromagnetic transducer (41). The electromagnetic transducer (41) is preferably of the moving coil geophone type which provides an electrical signal at low impedance which can be coupled through relatively long leads to a remote control facility.
