Problems solved by technology

The traditional ignition burner mainly has difficulty in ignition, easy tempering, fire off and fire extinguishing, weak flame rigidity, unstable flame detection signal, which leads to misjudgment by the flame detection control system, short service life of the ignition rod electrode wire, and the ignition burner nozzle. The design is unreasonable, because it is located in a high temperature area for a long time, it is easy to burn out and other problems

Abstract

The invention discloses an ignition burner. The ignition burner comprises a fuel gas sleeve, an air sleeve, a burner nozzle, an ignition rod and a swirler, wherein a fuel gas inlet is formed in the fuel gas sleeve, the fuel gas sleeve is sleeved with the air sleeve, an air inlet is formed in the air sleeve, the burner nozzle is connected to one end of the air sleeve and is communicated with the fuel gas sleeve and the air sleeve, an electrode tip is arranged on the ignition rod and extends into the burner nozzle, and the swirler is arranged between the fuel gas sleeve and the air sleeve and is close to the burner nozzle. According to the ignition burner, due to the arrangement of the swirler, air entering the ignition burner from the air inlet can enter the burner nozzle under the action of the swirler, burning is stable, backfire and blow-off cannot be caused, and the stiffness of a flame is high; due to the arrangement of the ignition rod, a flame detection signal is stable (a flame detection current is large and is over 15 microamperes on average); due to the fact that an ignition control cabinet is in linkage with a burning control system, automatic ignition can be achieved.

Description

technical field [0001] The invention relates to the technical field of combustion, in particular to an ignition burner. Background technique [0002] With the rapid development of high-temperature air combustion technology, regenerative combustion technology plays a more important role in the combustion field, and various types of ignition burners have emerged as the times require. The traditional ignition burner mainly has difficulty in ignition, easy tempering, fire off and fire extinguishing, weak flame rigidity, unstable flame detection signal, which leads to misjudgment by the flame detection control system, short service life of the ignition rod electrode wire, and the ignition burner nozzle. The design is unreasonable, because it is located in a high temperature area for a long time, it is easy to burn out and other problems. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. The...
