The use of fuels is present in our daily lives, especially in the means of transportation (cars). They are also of paramount importance for carrying out manufacturing activities, since most machines work using fuel energy.
This product can be obtained through different raw materials, a fact that triggered a classification of fuels into solids, liquids and gases. Another classification, based on the origin of the substance used in the production of fuels, establishes fossil fuels and biofuels.
Solid fuels originate from firewood, sawdust, sugarcane bagasse, hard coal, peat, among others. These substances must undergo a transformation process until they are in the form of a very fine powder. Burning this material generates superheated gases that expand rapidly in a combustion chamber, thus providing energy for the machine.
Do not stop now... There's more after the advertising ;)
NASA (National Space and Aeronautics Administration, also known as the American Space Agency) developed a solid fuel from paraffin, which can be used in bus rockets space.
In the search for alternatives to replace oil, which will be exhausted from nature in a few decades, solid fuel becomes a great option. However, research must be carried out to reduce some disorders caused by this substance, as, for example, the proper destination for its by-products (aluminum oxides and the chloride of hydrogen).
