Multifunctional low-NOx automatic absorption type integrated pilot burner

Abstract

The invention discloses a multifunctional low-NOx automatic absorption type integrated pilot burner. The pilot burner comprises a gun barrel, a flame stabilizing tube, a three-way pipe, an extension pipe, a mixer, a fuel gas nozzle, a connecting pipe, an explosion-proof junction box, a multifunctional nozzle, a mixing nozzle, a fixed end head, an electrode, a control cabinet, a ceramic tube, an air adjusting plate and a micro-adjusting valve. According to the pilot burner, fuel is graded, the optimal fuel-air ratio is adjusted, so that rich mixture combustion and lean mixture combustion of thefuel is realized, and the NOx combustion emission requirement is reduced. According to the pilot burner, a plurality of burners can be simultaneously ignited simultaneously through on one pilot burner, an electrode is arranged, the automatic ignition function and the flame detection function are achieved; an operator is not needed on site, and all operation is conducted under control of a controlroom; and a ceramic tube and N positioning nails are arranged, so that the electrode is positioned in the center of a gun tube, ignition at any place of the electrode in the gun tube is prevented, and the problem of electrode discharge orientation is solved.

Description

technical field [0001] The invention belongs to the technical field of burner heating furnaces, in particular to a multifunctional low NO x Self-priming integrated permanent light. Background technique [0002] The permanent light is widely used in the burner of the heating furnace, and it is one of the important accessories to ensure the safety of the heating furnace equipment and maintain the stable and continuous combustion of the burner. The vast majority of heating furnaces are used in the petroleum and petrochemical industries, which have strict requirements for fire protection and explosion protection, which have high requirements for the safety and reliability of the lamp. [0003] Usually, most of the permanent lamps supporting the burner are manually operated, and most of them are ignited by manual ignition or torch ignition. During the ignition process, there is a safety hazard that there is an open flame operation outside the heating furnace equipment. At the sa...
