High energy cavitation process for producing water saturated hydrocarbon fuels from low grade heating oil (Mazut)

Mazut (low-grade heating oil) is widely used in housing maintenance and utilities. Today, it is used in almost every boiler room/house. The key advantage of using this kind of fuel in boilers is its efficiency and high calorific value. Another advantage is its low cost.

Viscosity is one of the most important properties of mazut. Due to its viscosity, the use of mazut without heating is difficult. Mazut requires heating before it can be poured into a tank or barrel, transported to and unloaded at destination. The problem arises from the fact that this substance is usually heated with hot steam which results in it collecting water from vapors. The water inhibits burning, thus reducing the amount of heat produced. To compensate for the loss of heat, higher input is required, driving the costs up.

Besides, the traditional fuel handling methods (sedimentation and separation) result in fuel losses, with the amount of waste reaching 8%. This, in turn, increases the amount of waste subject to disposal, and consequently, has a negative impact on the environment. Sedimentation and separation are less effective for high viscosity fuels produced by compounding due to their ingredients being highly heterogeneous and this, in addition to fuel losses, has a negative impact on the operation of the equipment.

Thus, the presence of water in mazut presents a major problem.

Since the improvement of the fuel quality will result in lower mazut consumption rate and larger savings, it is necessary to find a way to effectively separate or bind water to fuel.

The invention by I.L. Berezovsky (Application No. 2012108311, with a priority from 03/06/2012, submitted to the Federal enforcement authority on intellectual property of the Russian Federation). “High energy cavitation process for producing water saturated hydrocarbon fuels from mazut (low grade heating oil)” offers a solution to the said problem.

This invention in the field of power generation may be used to prepare mazut-based hydrocarbon fuel emulsion containing 35%-50% of fine-dispersed water. The fuel can be used in boilers, turbines and other heating facilities that utilize mazut as main fuel.

Upon the implementation of the invention the following technical advantages will be gained:

  • deceleration of the process of intensive dispersion (intensive cavitation);
  • dilatation of fuel in the area of intensive dispersion as it moves inside the channel.

These properties of water-mazut fuel lead to very effective burning, with high degree of combustion completeness and little or no sooting. Compared to the traditional mazut burning process, sooting is reduced by at least 80%-90%, nitric oxide discharge is reduced by 30%-55%, carbon monoxide content is reduced by 85%-95%, benzpyrene and other polycyclic aromatic hydrocarbons – by 60%-90%. In all instances, brighter flame luminosity is observed, with stress on the draft systems reduced by 10%. The method developed by I.L. Berezovsky affords preparation of fuel-water emulsions from commercially available mazut and water, allows recovery of water-saturated mazuts, treatment of industrial wastewater (certain limitations apply), treatment of technical water (adulterated with mazut, etc.), and treatment of waste produced after flushing fuel oil storage tanks and systems.
