Abstract

The invention provides a swirling burner based on a multi-nozzle structure. The swirling burner comprises a swirler, a porous cylindrical fuel gas spray pipe, a porous conical fuel gas spray pipe, an annular mounting fuel gas spray pipe, an outermost circle fuel gas spray pipe, a burner shell and a hole cover body, wherein the porous conical fuel gas spray pipe, the porous cylindrical fuel gas spray pipe, the swirler, the annular mounting fuel gas spray pipe, the hole cover body, an outermost circle fuel gas spray nozzle and the burner shell are sequentially distributed from inside to outside in the radial direction of the swirling burner. The turbulent burner based on the multi-nozzle structure is a novel low-nitrogen burner, the existing fuel grading and multi-point dispersion combustion control technology is comprehensively used, the turbulent burner based on the multi-nozzle structure is designed, and the burner has the characteristics of coarse flame of multi-point dispersion combustion and uniform distribution of thermal load in a furnace.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a burner, in particular to a swirl burner based on a multi-nozzle structure. Background technique [0002] The gas burner used in asphalt mixing plant evaporates the water in the cold aggregate and heats it to the rated temperature through the heat released by fuel combustion. Its thermal performance plays a vital role in the safe operation and economic benefits of asphalt mixing plant . However, nitrogen oxides produced with fuel combustion seriously pollute the atmospheric environment. For this reason, it is of great value and significance to study the influence of the structure of the burner on the flow field and the characteristics of nitrogen oxide emission, and to develop a low nitrogen oxide emission burner for asphalt mixing plants. [0003] The combustion of the burner in a limited space is quite different from that in a large space. The better the mixing effect of gas...
