Abstract

A kind of energy saving solid fuel, by various slag mucks, the slag spoil, slag, brown coal, low grade coals etc. are major ingredient, add glass powder Jiao  powder, petroleum slag, coke tar refuse, charcoal, silica, quartz sand, the boron slag, pyrite slag, the manganese slag, ground phosphate rock, the aluminium scrap powder, ferric oxide, magnesia, aluminium matter refractory mortar alumina, native copper, ferrous sulfate, starch, nitrate of baryta, calcium oxide, wherein also can add a certain amount of coal, through making 125 millimeters of diameters, on the normal cellular coal of 15 millimeters through holes of 12 φ is arranged after, burn at the family expenses cooking stove, proof is caught fire fast, firepower is concentrated, the flare height is 150～250 millimeters, and sustained combustion reached more than 1 and a half hours.

Description

Energy saving solid fuel from industrial and mining wastes

The present invention relates to a kind of is the solid fuel of major ingredient with the slag muck.

This solid fuel is that the waste residue with industrial and mining enterprises is a fundamental component.Along with the development of society, slag muck is increasing, and existent environment of people in serious threat, therefore, causes that more and more people pay much attention to and pay close attention to.

Fuel is human being's production, the essential a kind of solid fuel of life.From energy-conservation viewpoint, people always wish a spot of coal and obtain higher benefit, therefore, open up the problem that the new energy has just become the research and inquirement of world today's all trades and professions.

Purpose of the present invention provide a kind of cheap, aboundresources is easy to get, it is fast to catch fire, flame temperature is high, combustion time is long, need contain a small amount of coal or not contain coal and the waste residue that makes full use of each industrial and mineral is the solid fuel of major ingredient.

The said solid fuel of the present invention, its raw material mainly contains following several:

1, the waste residue of industrial and mineral of the present invention refers to the accumulative domestic refuse in town and country; Mixing ratios 50～70% such as coal ash, slag, chimney soot, coal gangue, bone coal, low grade coal.

2, ignition dope is as glass powder, coke powder, petroleum slag, coke tar refuse, charcoal, silica, quartz sand, boron slag, pyrite slag, manganese slag, ground phosphate rock, aluminum dross, ferric oxide, magnesia, aluminium matter refractory mortar alumina, native copper, ferrous sulfate, starch, nitrate of baryta and calcium oxide etc.Formula rate 20～30%.

3, coal: precentagewise joins 10～30%.

Below according to the particular case of above-mentioned several raw materials, in order to help to implement fusion by a certain percentage better, proportioning becomes six groups, its weight percent sum be 100%(have suitably be broken for powder according to combustion requirements) and add suitable quantity of water and mix thoroughly and can make civilian burning and industrial combustion.

Concrete proportioning is executed example: all be to make 125 millimeters of diameters, on the normal cellular coal of 15 millimeters through holes of 12 φ is arranged in family expenses cooking stove burning gained result.

One group of proportioning:

Coal gangue 40～50%

Coal 20～30%

Glass powder 8%

Coke powder 4%

Boron slag 8%

Calcium oxide 5%

Alumina 4%

Nitrate of baryta 1%

Two groups of proportionings:

Manganese slag 5%

Four groups of proportionings:

Bone coal 40～50%

Coal 20～30%

Glass powder 10%

Coke tar refuse 3%

Ground phosphate rock 5%

Magnesia 6%

Calcium oxide 5%

Ferrous sulfate 1%

Four groups of proportionings:

Chimney soot 40～50%

Coal 20～30%

Glass powder 10%

Boron slag 5%

Coke powder 5%

Ferric oxide 3%

Alumina 4%

Aluminum dross 3%

Five groups of proportionings:

Flyash 50～60%

Coal 10～20%

Glass powder 10%

Quartz sand 5%

Coke powder 4%

Pyrite slag 5%

Calcium oxide 5%

Starch 1%

Six groups of proportionings:

Rubbish 40%

Coal 30%

Glass powder 10%

Boron slag 5%

Silica 3%

Coke powder 5%

Alumina 6%

Starch 1%

Six groups of proportionings:

Low grade coal 70%

Glass powder 10%

Charcoal 5%

Petroleum slag 2%

Magnesia 5%

Native copper 1%

Boron slag 5%

Ferric oxide 2%

More than each proportioning group, the gross weight ratio is 100%, its combustion case is: catch fire fast, firepower is concentrated, stove hall temperature height, flare all reach 150～250 millimeters, the sustained combustion time reached more than 1 and a half hours.
