Solid Fuel Production Technology
Sep 15, 2017

Solid fuel is a new type of fuel, it can be ignited with a match, can heat food, ignite honeycomb, easy to carry, very popular. With the development of tourism and the improvement of people's living standard, solid fuel will undoubtedly have a great market.

I. Raw material formulation and production equipment

1, raw material formula: solid fuel production raw materials for smokeless wood charcoal powder (or anthracite powder), sawn wood powder, paraffin wax and alcohol, its weight ratio is: carbon powder (particle size 80 mesh, water content <10%) 60 saw wood powder (grain size 40 mesh) 12 paraffin (melting point 54-60 ℃) 20 alcohol (concentration 95%) 8 2, Production equipment: The main production equipment has a sandwich pot, grinding machine one (modified with old punch), stirring kettle Two, electric stove (or coal stove) one and sprayer. Indigenous production can be used in the research body, clamp stool instead of grinding machine, stamping machine.

Second, the production process

1, take paraffin 1 kilograms in the sandwich pot heated dissolved, to dissolve after all melt add 6 kilograms carbon powder, 1.2 kg of sawdust powder, stir side, keep 60 ℃ temperature stirring 5-8 minutes, paraffin that is with pulverized coal, sawdust powder mixed evenly, and then cooling standby.

2, above the fuel cooling to 250 ℃ below, will be 800 grams of alcohol into the sprayer, stirring side of the alcohol into the raw materials, quickly stir evenly, pour into a small basin, so that the mixture just fill, covered with plastic sheeting, to prevent alcohol volatilization.

3, the mixture will be loaded into the mold, on the punching machine or clamp stool to suppress the formation.

4, put the sandwich pot on the fire, put into 10 kilograms (only about 1 kilograms), after dissolving, will be molded raw material into the dissolved wax wrapped in a thin layer of wax, remove the cooling is solid fuel finished products, packaging can be sold.

III. Packaging and usage requirements

Generally 8 solid fuel is a box, weighing 20 grams per block. A box of two mosquito-repellent racks, used when the solid fuel on the mosquito-repellent rack, lit with matches, you can heat items.

IV. Considerations

1, solid fuel molding pressure requirements of 80-100 kg/square centimeter. Pressure is too small to compaction, not to burn, and alcohol is easy to evaporate.

2, after pressing into pieces, to quickly wrap the wax layer to prevent alcohol volatilization, is generally a person pressure, a person wrapped.

3, 20 grams of solid fuel half is round, 4-5 centimeters in diameter, in the middle of 6 diameter 0.5 centimeters of small holes (middle 1, around 5).

4, packaging In addition to the mosquito-repellent rack, it is best to do 1 of the tripod bracket, support heating or honeycomb.
