CN2409210Y - Anthracite briquette - Google Patents

Abstract

The utility model relates to an anthracite briquette which is a clean briquette fuel for overcoming the problems of poor ventilation and insufficient combustion due to stacking type combustion when an ordinary briquette is used. The utility model adopts a mode that through holes are arranged on a briquette body with a rectangular outer part towards the opposite surfaces of the briquette body from three mutually vertical side surfaces to enable the through hole on each side surface of the briquette body to be mutually vertical and crossed; each hole on the same side surface is mutually parallel. The structure not only creates conditions for the briquette to have favorable ventilating environment no matter how the briquette is placed in a furnace but also increases the combination area of the briquette, ensuring the sufficient combustion of the briquette, and the utility model is a novel clean fuel which is consistent with environment-protecting and energy-saving requirements and has convenient use.

Description

A kind of anthracite briquette

The utility model relates to a kind of clean type coal fuel.

The coal that present China uses in civilian and industrial furnace body is mainly based on raw coal, foam coal, lump coal, coal gangue and artificial coal briquette, wherein except that coal briquette, the problem that above-mentioned fuel mainly exists be have a large amount of obnoxious flavoures to discharge in the combustion processes and dust pollution serious, environment is done a lot of damage, can not adapt to current environmental protection, energy-conservation, economic, requirement efficiently.And artificial coal briquette (comprising civilian honeycomb briquette) is although there is advantage such as low pollutions, because it be the heap use of randomness in burner hearth, so regular meeting is poor because of ventilating, it is insufficient to burn, and has also limited it thus and has been used for the needs of boiler.

In order to overcome above-mentioned defective, the purpose of this utility model is to provide a kind of anthracite briquette, and it can guarantee that burning of coal is abundant and ventilation effect is good, is to be suitable for various boilers and the required clean fuel of domestic stove.

Technical solution of the present utility model is: the outer shape of this coal body is a rectangle, except that its upper and lower surface is provided with the through hole, and also is provided with through hole to its opposite respectively in two sides in addition that are vertical configuration with the coal body upper surface.

Each lateral through hole of coal body is mutual vertical interlaced setting, and is parallel to each other between each hole of same side.Aperture φ=the 10-20mm of each through hole in the coal body, the spacing distance between the Kong Yukong should be 3-10mm.

The utility model has the advantages that: because this anthracite briquette is equipped with through hole at its each outside surface, can both maintain good ventilated environment, increase burning area and created condition for it fully burns with this so no matter in stove, how to pile up.Again owing to the utility model is that the smokeless desulfurized coal of employing is that main raw material is made, it contains sulphur content below 0.2%, smoke dust discharge concentration and smoke discharge amount all are significantly less than the numeral of Beijing's environmental protection standard regulation, and the sufficient cost in coal source is low, and fundamentally changed hard coal burning-point height, passed the slow deficiency of fire, have promotional value, it also can drive the development of relevant stove and accessory simultaneously.

Description of drawings of the present utility model is as follows:

Fig. 1 is that axle of the present utility model is surveyed schematic perspective view;

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.

As shown in Figure 1, the outer shape of this coal body is a rectangle, and its specification can design according to the size of use body of heater internal furnace, chimney arch.The coal body of this moulded coal is except that being provided with the through hole 1 its upper and lower surface, and with coal body upper surface A be vertical configuration two side B, C also are provided with through hole 1 to its opposite respectively in addition.This is its fundamental difference with normal domestic column honeycomb briquette.

Each lateral through hole 1 of coal body is mutual vertical interlaced setting, and is parallel to each other between each hole of same side.Diameter phi=the 10-20mm of set through hole in the coal body, the spacing distance between the Kong Yukong should be 3-10mm, so that this moulded coal can also effectively be controlled air quantity when guaranteeing its intensity.

The size of its outer shape size of moulded coal of the present utility model, through-hole diameter and the spacing in hole all can have corresponding change according to the difference of the used type of furnace.

Claims (3)

1, a kind of anthracite briquette, the upper and lower surface of this coal body is provided with through hole, it is characterized in that, and the outer shape of coal body is a rectangle, and also to its opposite through hole is set respectively in addition two sides that are vertical configuration with upper surface.

2, anthracite briquette as claimed in claim 1 is characterized in that, each lateral through hole of coal body is mutual vertical interlaced setting, and is parallel to each other between each hole of same side.

3, anthracite briquette as claimed in claim 1 is characterized in that, the diameter phi=10-20mm of set through hole in the coal body, the spacing distance between the Kong Yukong are 3-10mm.
