The flame of the Olympic cauldron at the XXII Olympic Winter Games in Sochi, Russia, is powered by a state-of-the-art LPG vaporizer system supplied by Eclipse Inc. of Rockford, Ill., and Algas-SDI of Seattle, Wash. Since natural gas is not available in the Olympic Park, the cauldron is fired with propane fuel, which requires a robust LPG vaporizer system. The Eclipse/Algas-SDI system, which was chosen to precisely deliver the propane-air mixture required to fuel the massive flame, includes an Algas-SDI QM-100 packaged vaporizer that is heated by an Eclipse ThermAir 200 multi-fuel burner.

NBC News anchor Brian Williams called the flame, “the most powerful we have ever seen at any games. It sounds more like a Soyuz rocket blasting off.” The flame is visible from 220 miles above Earth.
