Abstract
In a burner in which fuel and gaseous oxidant are fed into the burner and combusted to produce a flame that extends out of an end of the burner, the noise produced by the burner is lessened by incorporating into the burner a baffle composed of a metal plate having a certain distribution of holes through the plate and a layer of metal filaments, and optionally a second metal plate.
