Abstract:
Global flame properties were measured as a function of
fuel mass in a series of experiments conducted on
gaseous pool fires burning in a quiescent environment.
The measurements included radiative heat loss, heat
transfer to the burner, and sensible enthalpy transfer
to the surroundings by convection. A large number of
fires was studied encompassing a wide range of pool fire
parameters. Measurements were conducted using methane,
propane, natural gas, and acetylene in burners varying
from 0.1 to 1 m in diameter, producing flames fom 0.1 to
2 m in height with total heat release rates from 0.4 to
200 kW. From these measurements, the combustion
efficiency was calculated for smoky fires.
