For can concise description for the purpose of the problem, below the utility model is used for coal-fired stove the stove circle all abbreviate this stove circle as.

During use, the lower end of this stove circle is shelved on the upper end of coal-fired stove, with the air inlet and the atmosphere of this stove circle.Because the air outlet that this stove circle communicates with the circle body inner chamber can carry out air feed to stove fire like this, and make stove fire concentrate on the middle part of this stove circle circle body all towards the center of this stove circle circle body above stockhole; Owing to contain a large amount of oxygen in the air-out of the air outlet of this stove circle, the carbon monoxide that incomplete combustion is generated becomes carbon dioxide in the upper furnace burning, makes burning fully, is difficult for taking place anthracemia.

As the optimization of the utility model, said circle body be shaped as circle;

The cross sectional shape of said air compartment is circular; It is made up of annular horizontal cover plate, the U-lag seat arranged up and down; The U-lag seat comprises that vertical cylindrical shape second circle body in inboard vertical cylindrical shape first circle body, the outside, the annular that is connected between first circle body and the second circle body lower end connect base plate; First circle body is lower than second circle body; The downside inner edge of cover plate has suitable vertical cylindrical shape the 3rd circle body of one and first circle body, and the height sum of the 3rd circle body and first circle body equals the height of second circle body, and the 3rd circle body overlays on first circle body, the downside outer rim of cover plate load places on second circle body;

The air inlet of air compartment is positioned at and connects on the base plate, and the air outlet of air compartment is distributed in the circumferential of the 3rd circle body.

Air gets into air compartment from air inlet, carries out combustion-supporting from the top of air outlet entering stockhole then.Because air compartment is made up of annular horizontal cover plate, the U-lag seat arranged up and down, makes that the air feed of this stove circle is effective, is not subject to external interference; In addition, the contact-making surface of annular connection base plate and body of heater upper end is big, also makes to be difficult for good stability when this stove circle is shelved on the body of heater upper end moving, misplacing.

Further optimization as the utility model; Said air outlet is the bar shaped notch of inside and outside perforation the 3rd circle body; The projection of bar shaped notch in horizontal plane is and is in tilted layout; The center of circle of setting the 3rd circle body is L to the vertical range of the center line of bar shaped notch, and the radius of the 3rd circle body is R, and the length of L is less than the length of R.

Above-mentioned setting, making air outlet whole is helix shape, the whole combustion air that forms rotation of the air-out of each air outlet; The time of staying above stockhole is long, and fire stroke is long, and combustion-supporting effect is good; Thereby the raising efficiency of combustion makes that burning is complete, efficiency of combustion is high.

Advantage reasonable in design, compact conformation that the utility model also has is suitable for Mold Making, can carry out large-scale production.

As multiple choices, the air outlet of air compartment also can be distributed in the circumferential of first circle body, perhaps is distributed in the junction of first circle body and the 3rd circle body.
