Burner System from Coleman
Keeping the flame burning strong and bright throughout the relay was the primary focus for the engineering team. Coleman’s objective was to manufacture a valve and burner system that would prevent the flame from being extinguished under widely varying weather conditions, such as temperatures well below 0°F and as high as 80°F, gusting winds up to 50 mph, heavy rain and high altitudes. Of course the flame also had to be highly visible.
“We are using a butane and propylene fuel mixture in order to give the flame a yellow luminous color that can be seen well by spectators,” said Randy May, Technical Director of Engineering and Design at Coleman. “A pressure regulator ensures the consistent flow of fuel regardless of temperatures or altitude.”
Each torchbearer carries the torch for about 20 minutes, so weight was another important consideration. “The center section of the body is made of aluminum with an aged look,” said Shelton “while the bottom part has a highly-polished finish, made of a chrome-plated plastic to keep the weight down.” In all, the torch weighs around three pounds and is almost three feet long.
