Hydro dynamical devices for ultrasonic cavitations processing’s of liquids, preparations water-fuel emulsion.
Made
by Centre Energy-Saving of Technologies the hydrodynamical equipment,
basically, is applied in fuel systems of power installations to preparation
high-grade, homogenous water-fuel emulsions /WFE/. The equipment can
be applied for compound fuel, oils; preparations of suspensions; in
oil refining, petrochemical manufacture. The developed technologies
for processing high viscosity fuels in hydro dynamical devices the
modulated high-frequency fluctuations, allow operating intensity cavitations
processes to carry out conversion of molecular structure of hydrocarbons
at a power level of the phase transformations.
After processing in installation My viscosity
of residual fuel of IFO-180, IFO-380, IFO - 700 decreases in 4, 5
times, density on 3 %, the temperature of flash is reduced on 30 %,
and the volume of residual fuel is increased by 3 %. Conglomerates
of residual fractions of fuel were crushed up to1-5 microns. The mix
fuels, prepared on the basis of 70 % of marine diesel fuel and 30
% of residual fuel, had viscosity 5 cSt, that corresponded to viscosity
of marine diesel fuel. Use high viscosity residual fuel, with the
improved properties raises profitability of working process of diesel
engines on 6 %.
With conversion of work of ship main engines on water-fuel emulsion/WFE/
the consumption of fuel is reduced on 12-15 %, in boiler units on
6-8 %.

 Particles of water in structure WFE. Division of a scale of a microscope 5 microns |
We makes in modular execution of installation such as UKDG. Installations are supplied with electro pump unit’s productivity of 4-6 m3 / h, means of automation, the signal system, monitoring devices, and valve armature. In hydro dynamical devices, up to dimensional row of particles 1-5 microns it is crushed 0, 5-0,7m3/h a water phase. It allows to ensure the functioning on WFE of the main ship diesel engine power more than 10000 kW, boiler units with consumption of fuel up to 150 t/daily. For processing fuel, on the given frequencies of fluctuations, hydro dynamical devices are supplied with regulating facilities.
Complete sets of the hydro dynamical equipment can be fragmentary established in fuel system of diesel engines, boiler units; gas turbines operate from energy streams of fuel. In the power installations working on water-fuel emulsion, except for decrease consumption of fuel, is reached significant improvement of ecological characteristics of exhaust gases. In the diesel engines working on WFE
- with the water-contents of 17-22 %, emission the NOx decreases on 30-37 %, SO2 on 50 %, H2S and the not burned hydrocarbons down in some times. It allows execute on ships demanding Appendices VI toMARPOL 73/78 on reduction of harmful emissions with gases.
With conversion of work on WFE the temperature exhaust gases of engines on an output from cylinders is reduced on 8-10 °C, the oil film on walls of cylinders, works in more comfortable conditions, thermal stress of details of cylinder-piston group accordingly decreases. With use in working process of diesel engines WFE:
- It is sharply reduced carbon deposits on surfaces of the basic details of cylinder-piston group, in all exhaust manifold a path;
- Speed of pollution of cylinder and motor oils is considerably reduced;
- Raise reliability of work of the fuel equipment, an operating time of fuel filters between next clearness it is increased in some times;
- Period of an operating time of diesel engines between the next maintenance service grows, expenses for repair are reduced;
- Profitability of diesel engines grows, owing to preservation during long term of operation, settlement parameters of a working cycle;
- Ultrasonic cavitations processing of fuel, before submission to a separator, allows to reduce losses of combustible fractions of hydrocarbons by 85 %;
- Inclusion in structure of fuel systems of hydro dynamical devices provides an opportunity of input in structure of fuel of the additives, allowing to improve ecological characteristics of exhaust gases, velocity of burning; to delete the polluted sewage, harmful waste products of industrial production;
- To reduce power expenses for heating of fuel in capacities, in heaters; The hydro dynamical equipment for preparation WFE, made by my enterprise equipment, is applied more than on 70 marine ships and fishery fleet, in fuel systems of heating power complexes of many enterprises. Some types of ships supplied with the equipment for preparation WFE, are represented on pages of the present document.

With conversion of work of the main engines VTBF 674/160-3 on WFE, the daily consumption marine residual fuel, on a mode of a full speed, is reduced on 5t to day, annual economic benefit reaches 150000 $ USA. The first installation in modular execution for preparation WFE such as UKDG multistage dispersion was made and applied on the transport refrigerator « the Passage of Hope », tests of installation were carried out in March, 1985, and the main engine on WFE worked reliably, the consumption of fuel on a mode a full power of engine was reduced by 12 %.
After data attainment of results, under the order of heads MFE the USSR, the succeeding series of tests during 1986 – 1987 it was passed with participation leading research institute, regional CPKB. During tests careful supervision over a technical condition of a diesel engine were carried out speed wear was determined, physical and chemical properties of fuel, water-fuel emulsion were investigated.
The carried out analysis, the received results, has allowed making the conclusion that speed of wears the basic units and details at work on WFE, at least, does not exceed values characteristic for dehydrated fuel. After realization of all-round tests MFH the USSR was accepted the decision on serial manufacturing and application of installations on transport ships and a fishing industry fleet. Installations were tested on stands diesel engines factories, gas turbines, in fuel systems boiler units. The information on results of work of installations is displayed in reports, published in special technical editions.
Changes in dynamic at burning of water fuel emulsion, in burner space of boiler units, can be observed visually. A torch burning WFE in comparison with dehydrated heavy fuel, it is reduced in volume, is shortened, and becomes transparent. Owing to increase a contact surface of fuel with oxygen of air, oxidizing processes are intensified. Participation in reaction of burning molecules OH accelerates process of burning of fuel, transfer of heat to surfaces of boiler units. Submission of air in burner space decreases, that allows reducing losses of heat with leaving gases. The temperature of gases decreases on 20-30°C. Change of parameters of burning in boiler units and structure of leaving gases convincingly testify to increase of efficiency of use of fuel. Water-fuel emulsion is a special kind of fuel; it is qualitative and quantitatively varying process of burning. The jet injected WFE, owing to a smaller superficial tension, collapses on border division phases between fuel and particles of water. Contained in drops high-dispersive particles of water, turning at heating in steam bubbles, instantly are crushed fuel on the smallest particles, increasing the area of contact of fuel with oxygen of an air charge. With rise in temperature the water phase dissociates on oxygen and hydrogen, their reaction in areas a lot of oxygen compensates expenses of energy on dissociating waters. Participation in reaction of additional quantity of hydrogen increases amount of products of combustion, changes of concentration harmful substances in gases. Manufacturing, delivery of the equipment, development of the engineering specifications on its application in structure of power installations, my enterprise is made on the basis of the contract. The equipment is protected by patents for inventions.
