Abstract

The utility model relates to a novel boiler combustion device which is provided with a funnel-shaped combustion chamber. An ash outlet is arranged at the tilting side of an upper surface. A water cavity wall having a plurality of tilting holes is arranged above the combustion chamber. A plurality of air inlets are arranged at the lower neck part of the combustion chamber. A coal gathering barrel is connected below the neck part, and a guide plate is arranged at the connecting point. A coal inlet funnel is arranged on the coal gathering barrel, and a screw propeller driven by a power unit or a coal feeding tank operated by a lever are arranged in the coal gathering barrel. The device reforms the traditional coal feeding way of the boiler, has the advantages of sufficient fuel combustion, high utilization rate, enhanced heat efficiency, fuel saving, pollution elimination, mechanical or semimechanical coal feeding and reduced labor intensity.

Description

The New-type boiler burner

The utility model relates to a kind of New-type boiler burner.

At present, most boilers all are that coal is added in from above on the fire grate, up burn from the bottom, and top coal just former because of being heated at unburned, and many incendivity compositions have just vapored away, and have caused the waste of fuel.

Goal of the invention of the present utility model provides a kind of New-type boiler burner, and coal is delivered to the combustion chamber from below, and fire burns in the above.The cigarette that the coal added from below produces burnedly during by top glowing flame has fallen.This is the reform to conventional boiler, and both fuel saving had reduced pollution again, had protected environment.

The structure of this New-type boiler burner is a funnel shaped combustion chamber, the inner surface of steel plate wall lays the fire-resistant soil layer of one deck, upper surface is to lopsidedness, and the side that tilts is provided with ash hole, is a water cavity wall that a plurality of concentric circles opposite tilts hole is arranged on the combustion chamber.The neck wall of combustion chamber is provided with the air inlet that several same inscribed circle tangential directions are opened, and links to each other with coal collecting cylinder under the neck of combustion chamber, and there is guide plate the junction, and a side of coal collecting cylinder has coal feeding bucket, in the tube coaling gear is housed.

Coaling gear can be machinery or half machinery, and this burner is installed in the bottom of boiler.

This New-type boiler burner is to the reform of present boiler combustion mode and innovation.From following coal, fire burns in the above, and the black smoke that is produced during the coal combustion added has below almost all been burnt during by top glowing flame, and fuel can fully burn, and improves fuel availability, has alleviated pollution simultaneously.This burner air inlet makes the air rotation, when having promoted fuel combustion flame by the water cavity wall, makes flame and thermal current continue rotation, has increased hot stroke greatly, has improved the thermal efficiency of boiler.Adopt machinery or coal mechanically partly, it is strong to have alleviated work, has improved work situation.

Description of drawings: Fig. 1, the front view of the New-type boiler burner of coal mechanically partly; Fig. 2, the front view of the New-type boiler burner of coal mechanically.Among the figure: 1, combustion chamber; 2, water cavity wall; 3, air inlet; 4, guide plate; 5, coal collecting cylinder; 6, coal feeding bucket; 71, coal loading box; 72, propeller; 81 levers; 82 actuating units; 9, ash hole.

Below further specify the structure and the embodiment of burner with reference to the accompanying drawings.

Embodiment one: see accompanying

drawing

1,1 its surface, funnel shaped combustion chamber is covered with fire-resistant soil layer, the upper edge is to lopsidedness, a side that tilts is provided with ash hole 9, the top, combustion chamber is the water cavity wall 2 that a plurality of concentric circles opposite tilts hole is arranged, it is the air inlet 3 that same inscribed circle tangential direction is opened that the following neck surface of combustion chamber is provided with several gradients, the lower end of neck links to each other with coal collecting cylinder 5, the junction is provided with guide plate 4, coal collecting cylinder one side is provided with coal feeding bucket 6, one coal loading box 71 is arranged at the bottom of coal collecting cylinder, and coal loading box 71 is by lever 81 operations.Lever is when pressing down, and coal loading box is upwards mentioned, and guide plate upwards opens, and coal is added to the bottom, combustion chamber; When lever upwards lifted, coal loading box descended, the guide plate closure, and one time the rabbler finishes.

Embodiment two: see accompanying drawing 2, be the New-type boiler burner of coal mechanically, remainder all as the structure of above-mentioned embodiment one, just be provided with a propeller 72 at the central shaft position of coal collecting cylinder, the bevel gear that bevel gear and gearbox axis are equipped with in the lower end of propeller shaft is meshed, drive propeller by motor, gearbox actuating unit 82 coal is sent into the combustion chamber, finish coal work.

Claims

1, a kind of New-type boiler burner, it is characterized in that a funnel shaped combustion chamber, upper surface tilts on one side ash hole, the upper end is a water cavity wall that has a plurality of concentric circles tangential directions to tilt, several gradients are arranged is the air inlet of same inscribed circle tangential direction to neck under the combustion chamber, links to each other with collection weldering tube below the neck, and the junction is provided with guide plate, coal collecting cylinder one side has coal feeding bucket, is provided with coaling gear in the coal collecting cylinder.

2, New-type boiler burner as claimed in claim 1 is characterized in that coaling gear is to adorn a coal loading box by lever one end.

3, be the New-type boiler burner according to claim 1, it is characterized in that coal collecting cylinder central shaft position installs a propeller, the gear of adorning on the gear of propeller shaft lower end and the gearbox axis is meshed.
