Abstract
The utility model relates to a direct-ignition burner of a small grease-gun for enriching oxygen and supporting combustion, which is composed of a coal powder burner and a small oxygen-enriching combustion-supporting grease gun which is arranged in the utility model. The coal powder wind firstly passes through an arc-shaped pipeline and is divided into a concentrated phase and a dilute phase current coal powder wind, the concentrated phase coal powder wind current and the dilute phase coal powder wind current respectively enter the burner, and the combustion-supporting wind of the coal powder burner is provided with an adjustable type cyclone device. The rotary angle of the combustion-supporting wind can be altered through regulating a box compass, the flame profile can be regulated according to the condition of the coal type so as to ensure stable combustion and avoid coking, and the small grease gun uses an oxygen-enriching combustion-supporting way and is matched with an ignitor and a fire examining device.
Description
Affiliated technical field
The utility model relates to a kind of coal powder fired boiler burner device, especially has the coal powder fired boiler burner of oxygen-enriched combustion-supporting small oil gun direct-fire function.
Background technology
At present, known coal powder fired boiler burner structure is to be made of the coal dust firing spout that square tube constitutes.Self is not with igniter this coal powder fired boiler burner, needs outside igniter and furnace high-temperature that coal dust wind is lighted.
In order to overcome the deficiency of existing coal powder fired boiler burner, the utility model provides a kind of coal powder fired boiler burner, and this coal powder fired boiler burner can directly be lighted coal dust wind.。
The technical scheme that its technical problem that solves the utility model adopts is: combined by coal burner and the oxygen-enriched combustion-supporting small oil gun that is contained in inside, utilize oxygen enrichment that fuel oil is fully burnt, very little amount of fuel just can obtain that a rigidity is strong, temperature higher stable torch, because this torch temperature can reach more than 2000 ℃, when coal dust is heated during by torch very soon, and make the pulverized coal particle pulverizing of breaking, lighted rapidly.According to the principle of fractional combustion, make coal dust in the just as far as possible fully burning of ignition of the boiler initial stage, reach the purpose of pulverized coal boiler ignition startup and low-load combustion-stabilizing.
The beneficial effects of the utility model are that coal powder fired boiler burner carries torch oil gun, and oxygen-enriched combustion-supporting is arranged, and can coal dust be lighted and fully burning.
