I-а Міжнародна конференція «Відкрита наука та інновації в Україні 2022», Київ, 27-28 жовтня 2022 р. UNIVERSAL MURANOV ENGINE WITH EXTERNAL HEAT EXCHANGE FOR ENVIRONMENTALLY FRIENDLY GENERATION OF CHEAP ENERGY Muranov Sergey, Muranov Ivan e-mail: smuranov111@gmail.com; tel. +38 050 819 82 10 One of the most important economic problems are : reducing the cost of energy, reducing the consumption of hydrocarbon raw materials, as well as switching to more efficient, reliable and environmentally friendly methods of energy generation Investors are offered an innovative project engine Universal Muranov Engine (UME) that radically reduces the cost of electricity generation (by 2-3 times) while improving environmental friendliness This engine is a deep modernization of the Stirling engine (SE) Matrix SWOT a Stsrling Engine (operating engines in USA, China, Sweden…) + Strength SE: unique properties for efficient power generation high efficiency, the ability to run on any type of fuel and from any external heat sources, noiselessness; - Weakness SE: high manufacturing cost; bulkiness of construction, heavy weight. + Opportunities SE: a wide range of applications, in particular in distributive power generation systems in cogeneration plants. - Threats SE: limitation of the scope of application due to high cost, large dimensions and weight. reduced SE reliability due to the complexity of the mechanical drive design. Universal Muranov Engine (UME) The upgraded Stirling Engine designated as the Universal Muranov Engine with external heat exchange, developed by S. Muranov and I. Muranov, can be the basis of a new highly efficient, reliable and environmentally cleaner energy. The deep modernization of the SE included: development of a crankless mechanism built exclusively on rolling bearings; a unique system for heat recovery from the walls of the working cylinder, a system of reliable seals of pistons operating without lubrication, a new efficient system of heat exchangers with a small dead space. During the modernization, significant shortcomings of the SE were overcome, the cost of manufacturing the engine was radically reduced, efficiency and reliability of operation were increased, the weight and dimensions of the engine were significantly reduced, expanded application areas. The upgraded new UME is able to compete with internal combustion engines. and also with gas and steam turbines in terms of application efficiency. At the same time, UME-based mini-CHP plants generate energy and heat 2-3 times cheaper than traditional power plants. This engine can also be used on any vehicles - cars, ships, yachts, submarines, etc. UME can work autonomously for a long time without any maintenance. The modularity of the design allows you to create engines with a power of 1-50 MW. This project is also of exceptional importance for the EU and Germany, due to the fact that it radically reduces the cost of electricity, reduces the need for hydrocarbons, contributes to the preservation of the environment, and also increases the competitiveness of industry, energy independence and economic efficiency. The project was developed and tested for operability in the 3D design system of SolidWorks. All the main nodes have a novelty at the world level and will be patented. Individual nodes were tested on full- size real samples. An investor is required to finance the prototype.
