Currently NFPA 68 (Standard on Explosion Protection by Deflagration Venting) utilizes a system of explosion hazard classification that relies on a deflagration index; as part of this project we attempted to find a different explosion hazard parameter called the laminar burning velocity. Throughout the project, the group designed and developed a dust combustion apparatus to experimentally determine the laminar burning velocity of a cornstarch-air mixture. The apparatus consisted of an air intake, dust hopper, mixing chamber, burner tube and a vacuum exhaust system and allowed a flame (about 4 to 8 cm long) to stabilize at the burner outlet. The measured laminar burning velocity showed good agreement with data published in literature.
