Redesign, Development and Construction of Powered Burner Head

Abstract

This paper presents the redesign of a burner mixing head that used on High Static Gas burner (HSG) product to mix the gas and air mixture before it is ignited. This burner operates in firing range of 60,000-400,000 Btu/hr. The objective of redesigning the burner mixing head is to improve the overall performance of the HSG burner. This design project deals with the mixing head of a powered gas burner utilizing both natural and propane gases. The mixing head’s function in a powered gas burner is to initiate the fuel gas into an air stream. The redesigned burner mixing head increases combustion efficiency by 3% compared to the original burner head. This new burner mixing head operates within a wider range of excess air of 5% on both the lean and rich side while still igniting reliably and keeping the CO levels under 400 ppm. The redesigned burner mixing head design meets all the criteria of the American National Standards Institute ANSI Z21.17 standard for domestic gas conversion burners. The redesigned burner mixing head was machined out of 304 stainless steel which makes the burner head have corrosion resistant properties this includes using corrosion resistant fasteners.
