Systems and methods are disclosed that may include providing a wellhead gas burner to burn wellhead gas produced from a wellhead to heat water and/or other chemicals used in hydrocarbon production and/or well completion processes, including, but not limited to hydraulic fracturing (fracking). The wellhead gas burner may include a pressure regulator and an expansion chamber that permit the wellhead gas burner to continuously operate and accommodate wellhead gas pressure fluctuations. The wellhead gas burner may also be configured as a primary heat source and integrated with a traditional propane/diesel gas burner system configured as a supplemental heat source. The wellhead gas burner may also be mounted to a mobile superheater truck.

A superheater truck comprises a shell, a heat source, a heat exchanger, at least two flame arrestors, a plurality of parallel rows of fins, and a plurality of corrugated fins disposed between the parallel rows of fins. The heat source is within the shell and comprises at least one inlet vent and at least one outlet vent. The heat exchanger is within the shell and is configured to exchange heat received from the heat source and a fluid within the heat exchanger. A first one of the at least two flame arrestors is at the inlet vent, and a second one of the at least two flame arrestors is at the outlet vent.

Spread of leaking combustion exhaust or the like is suppressed and a thermal fuse is made to operate in definitive fashion. A back flange is made to protrude so as to be directed toward a rear wall of an outer casing from a joint between a combustor casing and a heat exchanger casing to a location in the vicinity of the rear wall. A thermal fuse is arranged about the periphery of the heat exchanger casing so as to extend along a region near a protruding end edge of the back flange. The back flange is provided with a through hole, and combustion exhaust which leaks from the combustor casing is guided to the thermal fuse. A back flange which is similar thereto is installed at an upper location so as to straddle a tubing elbow. The two flanges are made to protrude beyond the tubing elbow.
