Abstract

The utility model provides a fuel block composed of coal gangue and refuse. The utility model is formed by that the coal gangue or the refuse, or the mixture of the coal gangue and the refuse is pressed. The fuel block is provide with a plurality of through holes, wherein, the through holes which are perforated up and down are arrayed in a close-packed hexagonal dot matrix mode. The fuel block can be burned in a special stove; the burning effect of the utility model is similar to the burning effect of high grade coal; the utility model is particularly suitable for civil use, reducing the pollution of the coal gangue and the garbage to environment, and saving large numbers of energy sources; the utility model has the advantages of simple manufacture and low cost.

Description

Coal gangue, garbage fuel piece

The utility model relates to a kind of alternative fuel, particularly a kind of coal gangue or rubbish and made fuel brick of the two mixture thereof of utilizing.

At present, the coal gangue that the colliery elutriation goes out, all throw aside as waste material, a large amount of coal gangues is difficult to dispose, seriously the infringement, contaminate environment, though the research that the processing of coal gangue is utilized again also has some achievements reports, all be to need huge investment as a huge industrial treatment method, therefore so far difficulty practice.A large amount of domestic garbages especially one compel at the urgency of eyebrow Jie a great problem to be solved.

The purpose of this utility model is above-mentioned coal gangue, rubbish two big refuses will be carried out simple process, makes the phase become refuse and is used into combustible material, has both solved the same topic of environmental pollution, can save a large amount of energy again.

The utility model is realized by following scheme, coal gangue or rubbish are pulverized, its particle is less than 4mm, add an amount of water and stir into moist shape, in mould, be pressed into fuel brick, on this fuel brick, have several through holes of up/down perforation with the mixture of this coal gangue or rubbish or coal gangue and rubbish, these through holes are close-packed hexagonal and put old formula arrangement, be each through hole with through hole adjacent around it between width between centers equate that all the diameter of through hole is 5-9mm, width between centers is 9-16mm between through hole.

The coal gangue of making by such scheme, the garbage fuel piece is put into special-purpose stove and accessory, can light burning voluntarily with ignition substance such as timber below, the combustion efficacy of this fuel brick is splendid, it is suitable with fat coal that it produces heat, be particularly suitable for civilian, as coal-fired stove be used for heating up water, cook, heating etc.Also can use as industrial fuel.

The fuel brick of this utility model, its raw material sources are extensive, and processing is produced simple and easy to do, and cost is low, adopts this fuel brick not only to reduce environmental pollution effectively but also saved a large amount of energy.

Fig. 1 is the vertical view of the utility model fuel brick.

With reference to Fig. 1, be to suppress the cuboid fuel brick that forms with the mixture of the coal gangue of pulverizing or rubbish or coal gangue and rubbish, several through holes that on fuel brick, have up/down perforation, these through holes are close-packed hexagonal and put old formula arrangement, be each through hole with through hole adjacent around it between width between centers b all equate, the diameter a of its through hole is 5-9mm, and the width between centers b between through hole is 9-16mm.The length size of fuel brick is decided by the special furnace set volume size.

Through-hole diameter a of the present utility model is with 6-7mm.Through hole width between centers b together is best with 10-12mm, and its combustion efficacy is best.

Its concrete making method is with coal gangue, and rubbish is pulverized, and makes its particle less than 4mm, adds suitable quantity of water and stirs into moist shape, in order to moulding, makes raw material with this coal gangue or rubbish or the two mixture, suppresses forming in mould.This fuel brick also can be made square or right cylinder.

Claims

1. a coal gangue, garbage fuel piece, mixture compacting with coal gangue or rubbish or coal gangue and rubbish forms, several through holes that on fuel brick, have up/down perforation, it is characterized in that described through hole is close-packed hexagonal and puts old formula arrangement, be each through hole with through hole adjacent around it between width between centers b all equate, the diameter a of through hole is 5-9mm, and width between centers b is 9-16mm between through hole.

2. a kind of coal gangue according to claim 1, garbage fuel piece is characterized in that the diameter a of described through hole is 6-7mm, and width between centers b is 10-12mm between through hole.
