The combustion optimization of composite solid fuels using domestic natural resources

In this article the change and determination of the chemical composition of the metal-thermal reaction is considered. For the increasing the duration of combustion and reduction the spud of metal-thermal reaction a bauxite (alumina), a coal (a mixture of alumina with silicon) and a natural mixture are added. A number of heat secretion reactions is reduced, and the heat dissipation ability is optimized. The aim of this article is a management by metallothermic processes speed and by burning duration with the help of heating value optimization of the prepared mixture from natural home raw material resources (bauxite, caoline) and aluminum oxide. The obtained mixtures have significantly higher characteristics compared to each of the original components. The novelty of the topic is the use of natural fossil resources (bauxite and caoline) in alternation of ingredients. From the obtained results it is sun that bauxite and caoline are more useful for metal-thermal reactions and it makes 6% of composition. It is found that the metallothermic composite solid fuel combustion occurs independently by releasing a large amount of heat. For this reason, there is the problem of controlling thermal processes and optimizing the heating value of bauxite, ammonium nitrate, potassium permanganate and glycerin composite mixture. The conducted researches show that the following should be observed for effective carrying out of oxides metallothermic reduction: the amount of heating temperature released during thermal processes should be greater than the melting temperature of the recoverable metal, as well as the product formed. Thus, it is possible to create a fuel composite with these thermal properties by optimizing the metallothermic composite fuel composition, and this king of composite solid fuels can be used in small-scale power generation and for household use.
