Energy-saving natural gas burner capable of preventing clotted slag in furnace

Abstract

The invention provides an energy-saving natural gas burner capable of preventing clotted slag in a furnace. The natural gas burner comprises a mixing chamber, a combustion chamber, a gas inlet, a combustion-supporting air inlet and an igniter, wherein the gas inlet and the combustion-supporting air inlet communicate with the mixing chamber, and the igniter is arranged corresponding to the combustion chamber; the outer side of the combustion chamber is provided with an interlayer with the upper end being opened; an opening of the interlayer is formed surrounding an outlet of the combustion chamber so that an air partition surrounding flames can be formed; air deflectors / air guiding columns are installed at the opening of the interlayer, all the air deflectors / air guiding columns are obliquely arranged and parallel to one another so that the air partition can be in a spiral shape; and the lower portion of the interlayer is provided with an air inlet. The flames are limited through air flow of the interlayer, so that the flames are prevented from fleeing outwards, and the situation that the clotted slag in the furnace occurs due to the fact that the flames make contact with the furnace wall of the combustion furnace is avoided; and meanwhile, the flames are collected under the action of the spiral air partition to form a fire pillar, a combustion area is concentrated, the precision is higher, and ore sand expanding is facilitated.

Description

technical field [0001] The invention relates to a burner, in particular to an energy-saving natural gas burner for an anti-caking furnace. Background technique [0002] With the development of the perlite expansion furnace industry, environmental protection and energy saving have been advocated as an important development direction. The old-fashioned kerosene burners are gradually eliminated and replaced by natural gas burners. Natural gas burners have high combustion quality and sufficient flame. The burner does not need multiple burners, only one large-size burner is enough, but the large-size burner has flame expansion, and long-term use will cause damage to the combustion furnace, resulting in burnout, short service life of the equipment, and high application costs. [0003] In order to solve the above existing problems, people have been seeking an ideal technical solution. Contents of the invention [0004] The purpose of the present invention is to address the defic...
