Project summary

Fuel and Energetic complex is the important part of the world energetic industry and of big importance for the economy of every country. Essential amount of generated energy, i.e. about 1/3, is spent for warming the living houses and industrial buildings. Cost of crude oil and production of the electrical energy is becoming more and more expensive because of assimilation of new deposits in new remote areas and in connection with need of significant financing on modernization of the power stations.

One of effective approaches to economy of the fuel is using the autonomous systems of thermal energy supplement with nontraditional high efficiency methods of thermal energy generation. Great attention is paid to developing the problem which can be separated into two subtasks, i.e. improvement of existing thermal systems and development of new solutions.

The basic element of any heat generation system is the source of heat. There is known a lot of thermal generators having different design and working with different fuels such as natural gas, solid or liquid fuel, electric power. Warming the working liquid in such systems is made by means of contact heater elements such as thermal electric heaters or water boilers. Work of such devices is connected to problems of fire safety and profitability of operation, owing to formation of adjournment inside or on a surface of working elements.

The problems of deriving of safe, highly effective systems autonomous heat supply exhibit the increased interest for various branches and separate work cycles. The significant economy in such systems is reached by no necessity to create the heat water pipelines because creation of 1 kilometer of such a pipeline costs $250,000; it is without the payment for rent of the land and costs of earthen works. The additional, significant economy is achieved at elimination of expenditures on a upkeep and repair of these pipelines. Development of autonomous thermal systems, capable to ensure increased reliability and fire safety is an actual task. Such systems can be of great demand at petrochemical complex, for example, in chisel platforms, gas transportation stations, and gasoline stations for car supply.

Use of systems with hydrodynamic heating a liquid allows to avoid shortages of traditional heat systems and to provide a raised safety of a system. Heating the liquid in such systems is processing by transmission of the mechanical energy from the electric motor, which for especially responsible technological lines can be made in explosion-proof variant, through the driving wheel of the centrifugal pump of a working liquid circulating in a closed loop. In such systems there is no problem of formation of rigid ferrite oxides on a surface of heating elements. The mechanical energy of a driven liquid transfers to thermal energy while passing the liquid through the special hydrodynamic device (antiradiator). In such systems only the electrical energy is used. This circumstance raises the energy independence of a system and increases its reliability on serviceability.

Use of hydrodynamic, water systems of heating is much more efficient in comparison with air systems, which in conditions of average latitudes are less economic and are reliable in comparison with tight, water systems of heating, which ensure faster, process of heating of locations. An additional benefit of such systems in comparison with the air heaters is the possibility of supplement of the house and building by hot water, by the way, the process of heating is made for a short time (few minutes).

These hydrodynamic thermal systems based on the given principle of generation of a thermal energy can be used in mobile installations; in this case, the interior combustion motor can be used instead of the electric motor. Such variants of fulfilment of thermal systems allow to solve the problems of extreme emergencies of centralized heat supply, by re-switching a heating system of a residential building on the mobile installation. Mobile thermal installations also allow to ensure comfortable conditions on temperature conditions in mobile houses and large tracks.

The significant amount of research and engineering works is devoted to a solution of the given problem. There have been created various systems distinguished by a wide gamma of designer solutions. Such systems have the exit parameters considerably distinguished each from other. The creation of new systems providing maximum effect from application of the explained above method of the energy transferring is a complicated optimization task. The given circumstance shows importance of conducting of works in this direction.

Researches and development of such combined hydrodynamic systems allows to make significant promoting for their more efficient use, and also expansion of area of their application.

The essential promoting on use of the hydrodynamic thermal systems is possible on the basis of engineering a technique of projection and manufacture of such systems with the given parameters. The given technique allows to reduce considerably searching the optimum solutions as much as possible satisfying to posed tasks, essentially reduces a level of financial expenditures on development of autonomous thermal systems.
