Energy-gathering and vortex-heating combustor

Abstract

The invention discloses an energy-gathering and vortex-heating combustor. The combustor comprises a magnetically actuated energy-gathering module, a vortex-heating and rotary-spraying combustion module and a furnace opening sealing cover module, wherein the magnetically actuated energy-gathering module is installed above the vortex-heating and rotary-spraying combustion module, the vortex-heating and rotary-spraying combustion module is installed on the furnace opening sealing cover module, the furnace opening sealing cover module is arranged on a furnace cover base installed on a hearth, the magnetically actuated energy-gathering module is provided with an air fuel flowing cavity, a rifled fuel gas combustion pipeline is arranged in the vortex-heating and rotary-spraying combustion module, an inlet end of the air fuel flowing cavity of the magnetically actuated energy-gathering module communicates with an externally connected fuel gas supply pipeline, an outlet end of the air fuel flowing cavity communicates with the upper end of the rifled fuel gas combustion pipeline, and the lower end of the rifled fuel gas combustion pipeline penetrates through the furnace opening sealing cover module and extends into the hearth. According to the combustor, the range of the rotational flow area of flame is expanded, sufficient combustion is achieved, no dead corner is left, the temperature is uniform, the heat value is improved, and the combustion efficiency is maximized.

Description

technical field [0001] The invention relates to an energy-gathering vortex heat burner used in an industrial kiln combustion system, in particular to an energy-gathering vortex heat burner for a carbon roaster. Background technique [0002] In the combustion system of industrial furnaces, the burner is the key equipment for combustion efficiency. In the past, the burners, especially the burners of the carbon roaster, still used a straight-through pipe as the burner, which was too traditional and aging. The spray state of the burner is in a conventional columnar flame, and the ability to diffuse heat after mixed combustion in the furnace is extremely poor, and there are too many dead angles in the furnace. In addition, the sealing and caliber of the furnace mouth directly affect the heating and heat preservation. The product medium is always under uneven temperature, which affects the low quality of the product and the long time of temperature diffusion, resulting in difficu...

Problems solved by technology

[0004] However, due to the limitation of the long distance of the gas pipeline of the carbon roaster, that is, the hose of the burner (generally more than 4 meters), the burner (burner) of the roaster is connected to the natural gas pipeline, and there is a very long tube, which doubles the combustion of magnetic energy. The consumption reduction device (magnetic energy-concentrating accelerator) must pass through this pipe to reach the burner (burner). Because of the long distance, the double-fault combustion magnetic energy-consumption reducing device (magnetic energy-concentrating accelerator) is also hindered by the effect of use. is not good enough to perform its function well
