ANTI-BACK FIRE STRUCTURE OF LOW NITROGEN OXIDES BURNER

摘要

a fire receiving burner(2) having a slit shape fire receiving port(21,22) in side of a main fire port(11) of a flat shape main burner(1); a common suction port(22) sucking the mixed gas independently to the main burner and formed in the fire receiving burner(2); and a control part for preventing a back fire positioned in the upstream section from the fire receiving port and formed in the fire receiving burner(2); is disclosed. Thereby, it is possible to effect a stable combustion and to prevent a back fire in pre-loading combustion.
