The method of burning fume, including combustible gases and gas-borne particles, comprising moving the fume in a tube having a blind end and one or more slits in the tube short of the end, while the fume is at least partially at ignition temperature, and emitting the fume into the air, the slit width and the slit total area being chosen such that the fume velocity through the slits will be more than the flame velocity and up to the flame blow-out velocity. The device includes a tube having a closed end and slits having a width between one-eighth and 1 inch and preferably about five-eighths inch, and a length of between one-eighth and one-half of the circumference.
