摘要： The present disclosure relates to relates to an industrial premixed gas combustor using internal exhaust gas recirculation and an operating method thereof. Particularly, the industrial premixed gas combustor using internal exhaust gas recirculation includes: a fuel chamber that is provided in the central part of the interior of an injection block surrounded with an output end of the oxidizer supply chamber; an injection block that has a plurality of injection channels where oxidizers are introduced from the oxidizer supply chamber 10 and fuel and the oxidizers are mixed and injected; an orifice for fuel injection that is provided in-between the fuel chamber of the injection block and each of the injection channels, and injects fuel inside the fuel chamber to the injection block; and an internal recirculation tube that is formed to be spaced apart from the outer surface of the output end of the oxidizer supply chamber at a predetermined interval and to extend toward the outlet, and recirculates exhaust gas due to combustion.
