Abstract
A flameless igniter has a special shape and includes a flow control port to make efficient use of fuel during a flame ignition process associated with a tank burner of a fluid fuel system. The igniter uses a spark to ignite fuel and includes a handle and a spark gap whereby the igniter is effective even in difficult-to-reach locations on a tank burner.
Claims2
A flameless igniter for use with a tank burner of a fluid fuel system comprising:
- A) a base element which includes
- (1) a handle having a proximal end, a distal end, a top surface and a bottom surface,
- (2) a bowl element on the distal end of said handle, said bowl element having
- (a) a crescent-shaped longitudinal cross-section,
- (b) a concave upper surface,
- (c) a convex lower surface,
- (d) a bore extending from the upper surface of the bowl element to the lower surface of the bowl element to fluidically connect the upper surface of the bowl element to the lower surface of the bowl element,
- (e) the upper surface of said bowl element being in the shape of a ellipsoid of revolution;
- and
- B) an igniter system which comprises
- (1) a power source mounted on the bottom surface of said handle near the proximal end of said handle,
- (2) a switch element mounted on the top surface of said handle near the proximal end of said handle,
- (3) a first electrical conductor mounted on the bottom surface of said handle and electrically connecting one side of said switch element in series to one side of said power source,
- (4) a spark gap element mounted on the upper surface of said bowl element adjacent to said bore and having
- (a) a first electrode mounted on the upper surface of said bowl element adjacent to said bore,
- (b) a second electrical conductor mounted on the bottom surface of said bowl element and extending through said bowl element and connecting said first electrode in series to a second side of said power source,
- (c) a second electrode mounted on the upper surface of said bowl element adjacent to said bore and spaced from said first electrode, said second electrode being positioned on a diametrically opposite side of said bore to said first electrode so that said bore is interpositioned between said first and second electrodes, and
- (d) a third electrical conductor mounted on the bottom surface of said bowl element and extending through said bowl element and connecting said second electrode in series to a second side of said switch element;
- C) said power source and said spark gap being sized so a spark jumps from one electrode to the other electrode when said switch element is closed.
