Abstract
An improved premix gas burner design suitable for use in a metal melting furnace which has long service life, a low degree of maintenance, is easily cleared in case of burner blockage, allows inspection of the combustion chamber or furnace interior and still maintains the desired turndown capabilities of premix gas burners. These results are achieved by providing usual and/or physical access to the interior of the burner through a novel access tunnel and by providing a dual composition refractory combustion chamber.
