The HEAD DB II burner system is another of the innovative features of the HEAD Balloon. While it appears to be a single burner, the DB II burner is really much more. The burner is actually two complete redundant systems all the way up to the coils. Two separate fuel systems feed the two separate blast valves mounted in the polished stainless steel housing. The two blast valves direct fuel into the four 3/8" stainless steel vaporization coils and on into the 8 orifices. The burner is normally flown using one blast valve at a time. Using a single blast valve, the burner produces approximately 10 million BTUs at 100 psi (59oF), 13 million BTUs at 125 psi (70oF) and 15.5 million BTUs at 140 psi (80oF). The second blast valve not only gives you redundancy, with the same power, it also gives the capability for additional burner output. By using both blast valves at the same time the burner output is increased from 45% to 70% depending upon the fuel pressure.

Multiple orifice technology and the design of the orifices make the DB II burner one of the quietest burners flying. The DB II burner is equipped with two independent vapor pilot lights. The burner quickly mounts into the gimbal frame by means of two quick pins and has a 360o gimbal with over 45o of tilt. You can easily gimbal the burner and operate both blast valves with one hand.

The DB burner, double burner system is also available. The liquid propane lines are 5/16" high pressure hoses.
