A burner and a method for adjusting the flow through the burner

The present invention discloses a burner and burner adjustment through flow methods. Yaki said end cap comprises an end cap extending radially across a portion of the burner, and comprises an upstream surface and the downstream surface of the separating axially. A combustion chamber located downstream of said end cap. Premixing tube extending through the premixer tube from a downstream surface proximate the upstream surface of the inlet, through said end cap to provide fluid communication, and the premixer tube includes means for adjusting said plurality of through pre-flow mixing pipe member. A method of adjusting the flow through method for the combustor, comprising: a working fluid to flow through the end cap extends axially through the first set and the second set of premixer tubes premixer tube, wherein said second set of pre-mixing tube includes a flow adjustment member through the second set of pre-mixing pipe; and the fuel flow through the first set of pre-mixing tube or the second set of pre-mixing tube.
