Mykolaiv scientists develop trigeneration technology


A group of young scientists of Admiral Makarov National University of Shipbuilding for the first time in Ukraine conducted successful research on trigeneration and obtained three forms of energy - electrical, mechanical and thermal. Their scientific work is called Trigeneration technologies for stationary and marine energy.

Ukrinform correspondent reports about this.

"We had a successful three-generation study on obtaining three forms of energy - electrical, mechanical and heating. They focus on the development of energy-saving and energy-efficient technologies, such as in shipbuilding and in the stationary energy sector,” one of the authors, Candidate of Technical Sciences, Asssistant Professor Dmytro Konovalov says.

According to him, one of the main objectives was to increase the efficiency of conversion of chemical energy of the primary fuel into its other types. At the same time, both, the internal combustion engine or gas turbine can be used as basic units.

This development will be of interest to all those who by exploiting a large and average power engine strives to reduce fuel costs and obtain additional sources of heat, cold and electricity. The spectrum of applications is vast, from large industrial plants that generate energy for their own needs, thermal power plants and gas transportation systems to supermarkets and the public sector.

"We've been working on this project for a period of 5-6 years. This study allows obtaining energy in three forms - electrical, mechanical and refrigeration for air conditioning systems, or heat energy for cogeneration and heat supply systems," Konovalov said.

The companies that specialize in the use of heating systems, air conditioning became interested in the trigeneration technology of Mykolaiv authors. Among them, Mykolaiv company Sandora, which belongs to the U.S. PepsiCo. For the first time, not only in Ukraine but also in the CIS, this technology was introduced in the installation of autonomous power, heating and cooling systems. The economic effect of its use is UAH 6 million.

Also, these technologies have been used in power plants of such companies as the State Gas Turbine Research and Production Complex Zorya-Mashproekt , PJSC Factory Ekvator (Mykolaiv), PJSC Central Design Bureau Korall, SE Central Design Bureau Chornomorets (Sevastopol). The total economic effect of the introduction of these innovations at these plants amounted to more than UAH 1 million.

It should be noted that this work started to arouse an interest abroad. In particular, China became interested.

The developers, Candidates of Technical Sciences, Assistant Professors Dmytro Konovalov, Andriy and Roman Radchenko and graduate student Rostyslav Ryzhkov became prize winners of the Verkhovna Rada of Ukraine for outstanding achievements in fundamental and applied research.
