Abstract
A membrane for radiant gas burners comprises a fabric (18) of metal fibers. The membrane has a surface which has a permanent undulation to such a degree that its surface area is at least five per cent greater than the surface area of a comparable flat membrane. In a preferable embodiment, the amplitude and the pitch of the undulation is such that, in operation, heat is radiated to and reflected from the flanks (24', 24') of the undulation. The result is an increased radiative output and radiative efficiency.
