Associate Professor of the Department of industrial heat power engineering, South Ural state University has developed a power technological complex on the basis of solar collectors, which will integrate elements of renewable energy power plants.

The development of renewable energy are widely distributed in America and Europe. However, most of them relate mainly to global objects — solar and hybrid power plants. SUSU scientist interested in the question of the use of elements of renewable energy, namely solar collectors, applied to thermal power plants on limited fuel.

The idea of development of the energy technological complex on the basis of the solar collectors was formed after studying the experience of implementation of contact heat exchanger with an active nozzle at Chelyabinsk metallurgical plant in the 1980-ies. However, at the time the tests were deemed unsuccessful, in view of the ineffectiveness of development.

Similar solutions were used abroad until the beginning of the active implementation of elements of alternative and renewable energy in industry. The most interesting experience of the scientist thought the use of solar collectors. Using a patented SUSU flue gases after the air heater comes in either a regenerative or contact heat exchanger is combined with a heating capacity of solar collector. A set of design features and type of contact between two media gives rise the efficiency of the boiler unit.

Before researchers had two basic questions — how and where to put the collectors. According to his calculations, the solar collector must be installed outside the boiler plant for more efficient use of low-intensity solar radiation.
Energy engineering complex, was developed by Konstantin Osintsev in the framework of the Project 5-100 is a boiler unit or a power unit designed to generate energy in the form of steam.

«Production of heat energy based on fossil fuel is associated with losses that we cannot exclude. Therefore, it remains only to improve the combustion processes and utilisation of flue gases. After the process of combustion of fuel are formed flue gases, including water vapor. The vapor condensation can give us an additional increase in the efficiency of the entire installation,» explains Konstantin.

Then heated in the heat exchanger water should be used in the heating circuit of the power plant. Depending on the capacity of the boiler unit of power unit you can significantly increase efficiency, which undoubtedly is an advantage from the economic side.

With some modification of the heat exchanger, it can be turned into a contact heat exchanger with an active nozzle that is directly condensing water vapor from combustion products. In the condensation part aggressive gases, such as nitrogen oxides or sulfur congenerous and the cooled gas goes into the atmosphere than it helps and also the ecology of the region.

In this development, there are analogs, but the solar collector are placed on individual houses, but do not apply to large energy, only in its renewable part. Konstantin Osintsev the first attempted to combine renewable and non-renewable energy. Ideas for combining renewable and non-renewable energy is partially reflected in the article in Scopus, which was released in may 2017.

In a further development can be used not only in power but also in the residential sector, for boilers of small capacity.

The plans of the scientist to create laboratory benches and prototype, and then try to commercialize it.

«If at the end of the manufacture of stands we understand that we need patents for more details of the heat exchanger, that will make them the objects of intellectual property rights, and then we will go out to organizations to invite them to implement developments. The unified heat exchanger and it can be applied in almost any region», — said Konstantin Osintsev.

In the future the use of systems based on solar collectors can partially solve the problems associated with the consumption of resources for the Chelyabinsk region is a fairly urgent question. The introduction of these plants will partially help to save money and reduce dependence on coal companies.
