Abstract

The invention discloses a multi-mechanism composite atomized fuel nozzle structure. The atomized fuel nozzle structure comprises an inner pipe, an outer pipe, a mixer and a nozzle, wherein the inner pipe is communicated with a fuel inlet and is used as a fuel channel; the outer pipe is arranged on the inner pipe, an atomizing medium channel is formed between the outer pipe and the inner pipe, and an atomizing medium inlet communicated with the atomizing medium channel is formed in the pipe wall of the outer pipe; the mixer is arranged on the discharge port end of the atomizing medium channel and is communicated with the fuel channel and the atomizing medium channel; the nozzle arranged on one end of the outer pipe is arranged on the discharge port end of the mixer, and the front end of the nozzle is provided with a plurality of spraying holes; an atomizing structure for atomizing fuel is arranged between the mixer and the inner pipe. The atomized fuel nozzle structure has the advantages of simple structure, small fuel atomizing particle size, good atomizing particle size evenness, high regulating ratio, low atomizing agent consumption, low noise, good energy-saving effect and the like.

Description

technical field [0001] The invention relates to the field of combustion equipment, in particular to a multi-mechanism compound atomization fuel nozzle structure. Background technique [0002] Fuel atomization refers to the process of turning fuel oil into atomized oil droplets through the burner using mechanical energy or energy from other media before oil fuel is burned. The quality of the fuel atomization effect directly affects the combustion state of the fuel and the thermal efficiency of the equipment. The atomization effect of fuel mainly depends on the nature of the fuel itself and the structure of the burner. [0003] At present, the atomization methods used by most oil burners in China are pressure atomization and mechanical atomization. These atomization technologies have some disadvantages, such as burners are easy to block and coke, require high mechanical energy, and the combustion effect is not good. The method of transformation is single, etc. [0004] For ...
