Solid Fuel A Solid Combustible Substance That Produces Heat Or Power
Nov 06, 2017

Solid fuels are a major category of fuels. A solid combustible substance that produces heat or power. Most contain carbon or hydrocarbons. Natural wood, peat, lignite, bituminous coal, anthracite, oil shale and so on. After processing has become charcoal, coke, bricks, coal briquettes and so on. In addition, there are some special varieties, such as solid alcohol, solid rocket fuel. Compared with liquid fuel or gaseous fuel, general solid fuel combustion is more difficult to control, lower efficiency and more ash. Materials that can be used directly as fuel and as feedstock for the manufacture of liquid fuels and gaseous fuels or chemical products.

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.

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 bowl, so that the mixture just fill, 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.

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.


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 the block, to quickly wrap the wax layer to prevent alcohol volatilization, generally is to complete the compaction and package action alone.

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.
