The structure of the financial expenses of automotive businesses and boiler plants is quite varied, though it still allows to identify the main expenditures. First of all, it is the fuel, which accounts for no less than 40% of all costs.

Fuel homogenization devices are designed to increase the quality of combustion, thereby saving resources. Homogenized fuel features good performance, burns cleaner, increases the efficiency of boilers and has a sparing effect on the environment.

How to make homogenized fuel?

Generally, in addition to hydrocarbons, diesel fuel also includes water, paraffins, mechanical impurities and organosulfur compounds.

Fuel structure is such that most of its molecules are linked (polymerized). If such a mixture is ignited, the oxidation process will begin at the active side of large polymeric units. The combustion rate will decrease due to collisions with water molecules, while sulfur and paraffin will not burn out completely. These factors lead to incomplete combustion of the fuel mixture and toxic waste.

The question is what happens if the fuel is deprived of its “variability”? Fine dispersion and homogeneity of fuel mixture has a direct effect on its calorific value and combustion quality. In particular, we are talking about intensification of oxidation processes, breaking the bonds between molecules with further formation of free radicals, destruction of water polymer chains and transition into a finely dispersed state.

During the homogenization process, sulfur and paraffins break, resulting in the formation of surfactants. They isolate emulsion particles from each other, not allowing them to coagulate.

Today, there is a wide range of equipment on the market which can be used for homogenization of fuel and creation of water-fuel emulsions. The most promising in terms of profitability and achievement of the required quality characteristics are plants that operate based on cavitation effect. GlobeCore is involved in development of such equipment (USB-type units).

What is cavitation?

The phenomenon of cavitation was first mentioned over a hundred years ago. It was connected with the work of a British scientist Reynolds.

Cavitation is in some ways similar to boiling of liquid, but there are some fundamental differences. In particular, increasing flow rate relative to a body causes flow pressure reduction to the level of saturated vapor pressure (vacuum). This leads to boiling of the liquid and formation of cavitation steam bubbles of microscopic size. When these bubbles get into the high pressure are, they burst. Their sudden bursts cause hydraulic impacts, which result in the occurrence of a liquid compressional wave with ultrasound frequency. In case this wave contacts an obstacle, it just breaks its surface.

Why is it advantageous to use GlobeCore equipment?

GlobeCore USB-type plants allow production of high quality homogenized fuel, which does not break down even after prolonged storage. The use of GlobeCore regeneration technology also allows to:

  • Reduce fuel costs;
  • Improve consumer appeal of the processed fuel with respect to the initial product;
  • Use low-quality fuel feedstock, which also saves funds;
  • Improve reliability of engines and boilers;
  • Increase efficiency of diesel engines and diesel generators;
  • Reduce the amount of harmful emissions into the environment.
