IMPROVED BURNER WITH LOW NOX EMISSIONS |
摘要 |
A burner for use in furnaces such as in steam cracking. The burner includes a primary air chamber; a burner tube having an upstream end, a downstream end and a venturi intermediate said upstream and downstream ends, said venturi including a throat portion having substantially constant internal cross-sectional dimensions such that the ratio of the length to maximum internal cross-sectional dimension of said throat portion is at least 3; a burner tip mounted on the downstream end of said burner tube adjacent a first opening in the furnace, so that combustion of the fuel takes place downstream of said burner tip; and a fuel orifice located adjacent the upstream end of said burner tube, for introducing fuel into said burner tube. |
