METAL FIBER MEMBRANE FOR GAS BURNERS

摘要

The invention relates to a metal fiber membrane (1) for gas burners comprising a sintered metal fiber web with a pattern of a number of consecutive quadrangular porous zones (2) with each a width D, a length L and a surface of at least 100 cm2 and with intermediate sealed areas in the form of a grid (3) in which any distance D or L between each two adjacent rows of the grid is at least 40 mm, while the width B of each sealed area is between 5 mm and 20 mm. The porous zones are preferably rectangular. The membrane can be mounted in a flat or tubular arrangement in the burner.
