Abstract

The utility model relates to a hollow fire bar, which is arranged in a furnace chamber and used for cleaning out slag and overhead coals. The utility model can not pile up a great amount of massive coal slag and can make coals sufficiently overhead to enlarge the contact surface between coals and the air, and the air enters the furnace chamber after being preheated. In the utility model, an old-styled flat bottom fire bar is changed into a funnel-shaped bracket whose external point is upward, the top end of the bracket is a small circular ring, the bottom of the bracket is a large circular ring, the middle of the bracket is an intermediate circular ring, three different-sized upright posts which bend inward connect the three circular rings and the three circular rings are supported by the three upright posts into a funnel shape, and four legs are arranged below the circular rings.

Description

Hollow fire bar

The utility model is that a kind of being placed on is used for built on stilts fuel and makes it clean-burning new fire bars in the middle-size and small-size cooking stove.

Flat fire bars at present commonly used, because of the contact-making surface of fire bars and fuel is little, above the coal seam thicker, and often accumulate the bulk slag, so it is not smooth to ventilate, fire box temperature is low, fire is not prosperous, many dense smokes are wasted coal.

The purpose of this utility model just provide a kind of easily make that slag falls, the fully built on stilts new fire bars that increases the contact-making surface of air and coal of coal as far as possible.It can allow more air enter burner hearth smoothly, makes the stove fire burning vigorous.Few dense smoke.

The utility model is achieved in that the funnel-shaped bracket that original flat fire bars is made into point upward.This fire bars most advanced and sophisticated suitable for reading is a minimum garden ring, and end opening is a maximum garden ring, and the centre is a medium garden ring, and other has the inflexed column of several varying lengths, three rings are connected and supports the formation infundibulate.So just increased the contact-making surface of air and coal greatly, and made top and squeeze on every side, because fuel is fully built on stilts, air very easily circulates, and makes the very fast abundant burning of fuel.

Owing to adopt such scheme, not only can directly send into burner hearth heart portion to a large amount of air, and also up-narrow and down-wide because of the space of fire bars, so the big or small slag that burns down all easily falls, can not influence ventilation.

Owing to adopt such scheme, before air enters burner hearth, at first be heated into high-temperature gas in funnel inside, and then enter burner hearth to upper end aperture or fire bars space, so not only improved fire box temperature, also increased the jet power of air.

In a word, this novel can be fully built on stilts coal, make it thoroughly promptly to burn, province's coal two saves time.

As follows below in conjunction with description of drawings:

Fig. 1 is a front view of putting into burner hearth,

Fig. 1 is a vertical view,

1. base rings among the figure, 2. supporting leg, 3. in ring, 4. apical ring, 5. column.

Base ring among the figure (1) is identical with furnace diameter, and four legs (2) are arranged under it, apical ring (4), and interior diameter is 3 centimetres, in the upper end.In ring (3), be half of base ring diameter between the two, several inflexed columns (5) that length is different connect and support three rings, put funneling equably.

The size of hollow bar is decided with the size of cooking stove.Experimental result shows: the space of funnel stand can not be too small, and the tip can not be meticulous long, otherwise easily dissolve, and is not durable.It highly is no more than high 0.618 times of burner hearth, and what of column can fall bigger slag with the space on the base ring and be advisable, and the thickness cross section diameter of each part is the 12-14 millimeter.

Manufacture method: urib founding.

Claims

1, a kind of being placed on is beneficial to removing slag and support and built on stilts coal in the cooking stove, makes it clean-burning fire bars, it is characterized in that: the funnel-shaped bracket of a point upward.

2, according to the described fire bars of claim 1, it is characterized in that: the funnel tip is a minimum annulus, and end opening is a maximum annulus, the centre is a medium annulus, and other has several aduncate columns that length is different, three rings are connected and supports, form infundibulate, four legs are arranged below.

3, according to the described fire bars of claim 2, it is characterized in that: the size of fire bars and the space of column are that little bottom, top is big.
