Abstract

The invention discloses a nozzle, and relates to the field of industrial combustion, in particular to a fuel oil atomizing nozzle for a combustor. According to the invention, the inner wall of the nozzle shell forms a first cavity; a through hole is formed in the first cavity and communicates with the first cavity and the spray head; and the first channel and the second channel are communicated with the first cavity through the swirler. The nozzle integrates the advantages of a mechanical pressure type nozzle, an inner mixed gas auxiliary nozzle and a bubble atomizing nozzle, overcomes the defects that the mechanical pressure atomizing nozzle is sensitive to injection pressure and small in load adjusting range, and overcomes the defect that the gas auxiliary nozzle is high in gas consumption rate; and meanwhile, the defect that the atomizing effect of a pure bubble atomizing nozzle is greatly influenced by a two-phase flow pattern is overcome. The atomization quality is greatly improved, and the atomization fineness and uniformity are improved.

Description

technical field [0001] The invention relates to the field of industrial combustion, in particular to a fuel atomizing nozzle for a burner. Background technique [0002] The fuel atomizing nozzle is an important part of the burner. The performance of the fuel nozzle is directly related to the use effect, performance and life of the entire burner. important factor. [0003] Traditional fuel nozzles often use mechanical pressure materialization and medium atomization. The common nozzle of mechanical pressure atomization is a simple centrifugal nozzle. Coarse particle size. The gas-assisted nozzle has the disadvantage of high gas consumption rate, and the atomization effect of the pure bubble atomization nozzle is greatly affected by the two-phase flow pattern. [0004] Combining the characteristics of various types of existing atomizing nozzles, how to improve the atomization quality and improve the atomization fineness and uniformity is an urgent problem to be solved by th...
