Abstract

The present invention discloses environmental protective solid fuel. The present invention considers charcoal powder and potassium nitrate as the raw materials to be matched with diatomite and plant gum adhesive to be stirred completely under normal temperature and normal pressure for kneading and forming the solid fuel. The solid fuel can be made as columnar, stick-shape appearance or other shapes. The present inventions has the characteristics of easy ignition, burning as blind fire or anneal, slow combustion speed, low-pressure resistance, low-temperature resistance, strong continuously combustion capability, thoroughly combustion and little ash forming quantity. The combustion product of the present invention does not contain harmful and toxic substance and meets the requirement of the environmental protection.

Description

A kind of solid fuel

Technical field

The present invention relates to a kind of fuel, particularly relate to a kind of solid fuel.

Background technology

Aspect solid fuel, both at home and abroad chafing dish charcoals, warming stove coal briquettes etc. of igniting that adopt as Chinese patent CN89105310.7 " a kind of manufacture method of multi-purpose solid fuel " more.But mostly these solid fuels are with the coal-based solid fuel of naked light incendiary, it is big to have oxygen-consumption, combustionvelocity is fast, incomplete combustion becomes the ash amount many, and only is applicable to family, picnic and outdoor heating etc., be not suitable for long-time dying fire or anneal burning under the hypobaric hypoxia envrionment conditions of highlands, particularly the Olympic torch is lighted and is transmitted at 8844 meters of Everest peak Beijing2008 year, be Mount Everest on the Olympic Torch kindling material band, and existing solid fuel is difficult to realize dying fire burning or anneal burning.In addition, it is raw material that " solid burning block " of U.S. Pat 5573555A adopted charcoal, saltpetre and starch, but it is low and adopted and be different from diatomaceous other components as the starch content of glue paste, make that the solid fuel of moulding is bonding insecure, therefore cracky in transportation.

Summary of the invention

The object of the present invention is to provide a kind of solid fuel, it is easily flame-out or ignite other inflammable substance and the problem of going out certainly during smoulder under highlands hypobaric hypoxia, the low temperature strong wind condition to have solved solid fuel.

Solid fuel of the present invention, its component and content thereof are:

Particle is less than 100 purpose wood charcoal powders 85～93%

Particle is less than 100 purpose saltpetre 5～12%

Particle is less than 100 purpose diatomite 0～3%

The above-mentioned major ingredient of every hectogram adds:

Vegetable jelly 25～45%

Water 12.5～15%

All percentage ratios are weight percentage.

Solid fuel procedure of processing of the present invention is as follows:

(1) wood charcoal powder, saltpetre, diatomite are crossed 100 mesh sieves.

(2) vegetable jelly adds water and fully stirs, and makes vegetable jelly hydrolysis gelatinization make organic binder bond.

(3) wood charcoal powder, saltpetre, diatomite are mixed in proportion, add then, under normal temperature, atmospheric pressure environment, fully stir, mediate, form solid fuel by the organic binder bond that is made into than row.

(4) with solid fuel compression moulding.

Wherein, the described solid fuel of aforesaid method is pressed into right cylinder or rhoptry, and right cylinder can be with holes or not with holes.Cylinder diameter is 25～50 millimeters, and length is 30～60 millimeters.Can there be 1 to 5 hole at its place, circular section of hole cylinder body, and the aperture is 5～12 millimeters.Long 80～200 millimeters of claval cross section, wide is 15～20 millimeters, and height is 10～16 millimeters, and incline is smeared fillet.The solid fuel ignition of this kind shape size is abundant, easy to use.

Above-mentioned solid fuel can be processed into different shapes according to different purposes.

Solid fuel of the present invention can be under hypobaric hypoxia, low temperature strong wind condition dying fire burning slowly or anneal burning, afterflame becomes the ash amount few continuously, energy reliable ignition torch priming apparatus is nontoxic, environmental protection.

Specific embodiment

Embodiment 1

Wood charcoal powder 92% and the saltpetre 8% of getting 100 mesh sieves mix, and add 30 gram vegetable jelly and 12.5 by every hectogram major ingredient and restrain the organic binder bond that water are made in above-mentioned material, fully stir under normal temperature, normal pressure, mediate, and form solid fuel.

Again solid fuel is pressed into cylinder type, its external diameter is 42 millimeters, and length is 50 millimeters, and a centre hole, diameter are 12 millimeters.

Appoint and to get 5 on above-mentioned charcoal post, light one, 5 charcoal posts are gone here and there in order be contained in the safety lantern combustion chamber then, and rapidly safety lantern is put into normal temperature low pressure high wind experimental cabin with the high mountain steam stove.Start vacuum pump and blower fan after closing the cabin, keep cabin internal pressure 0.3bar, wind speed 15m/s, long run test 9.5h.The inspection of opening the cabin after the shutdown, charcoal post flameholding, afterflame power is strong, can the reliable ignition priming apparatus, combustion residue is a pale powder.Add this extraordinary solid fuel in good time, the long-time preservation of kindling material is not gone out.

This kind cylinder type solid fuel is mainly used in Mount Everest safety lantern or picnic picnic.

Embodiment 2

Got wood charcoal powder 93%, saltpetre 5% and the diatomite 2% of 100 mesh sieves, mixed, and in above-mentioned material, added 40 gram vegetable jelly and 15 and restrain the organic binder bond that water are made into, under normal temperature, normal pressure, fully stirred, mediated, formed solid fuel by every hectogram major ingredient.

Again solid fuel is pressed into rhoptry, the square-section is of a size of 15 * 10 millimeters, long 80 millimeters, 3 millimeters fillets of incline is simultaneously arranged.

Appoint and get one of above-mentioned carbon rod, light, put it in the warm handwarmer box, will warm up handwarmer then and be placed in the atmospheric low-temperature-20 ℃ environment, carbon rod energy stable burning 6～7 hours with lighter or match.About 40～50 ℃ of warm handwarmer box surface temperature, the feel temperature is suitable.

This programme is mainly used in warm handwarmer, chafing dish charcoal, touch charcoal, picnic picnic, convenient fuel etc.
