FIELD: power engineering.
SUBSTANCE: invention relates to power engineering, namely to environmentally safe and cost-effective methods and installations for generation of heat and mechanical energy. Power technological complex for generation of heat and mechanical energy includes power plant (1) consisting of combustion chamber, steam-gas turbine connected to electric power generator, oxygen supply lines, natural gas, water and carbon dioxide into the combustion chamber, as well as a cooling line for exhaust gases, which is configured to condense water and carbon dioxide. System additionally includes installation (2) of cryogenic air separation and system of coal mine (3) ventilation. At that, system of coal mine (3) ventilation is connected by line (5) of air supply from coal mine (3) with installation (2) of cryogenic air separation, which is made with possibility to provide supply of liquefied oxygen and liquefied natural gas to power plant (1), which is also configured to transmit generated electric power to coal mine (3), and besides, transmission of generated energy to installation (2) of cryogenic air separation. Also disclosed is method of operation of power technological complex.
EFFECT: technical result consists in improvement of efficiency and efficiency of complex due to increased use of thermal energy of media circulating in complex, improved environmental properties of the complex by enabling use of natural gas contained in coal mine air, and excluding emission of natural gas into atmosphere, as well as enabling complete collection of gas by-products.
