On Fire Severity of Flammable Gas

Article Preview

Abstract:

Flammable gases’s fire need more attention in spontaneous combustion study of coalmine. Their premixed combustion is modeled to deduce the corresponding temperature-time function. Basing on this function curve and Simon Ingberg’s early reports, their fire severity classification theory is established, including definition and equation of their fire severity, and definition of fire severity coefficient along with calculation of those coefficients of ordinary flammable gases. Applying this theory to a certain coalmine, calculate and audit fire severity of its 6 designed fire scenarios, in servitude to guidelines for fire protection technology there, and references for fire severity comparison among similar coalmines.
