Using of Hydrogen Sorbtion Storing Technology Based on Metal Hydrides for Cooling of High-Power Electric Generators with Steam Turbines

Abstract

The article analyzes the cooling systems that have become stuck during the operation of high-power electric machines, the importance of using water-cooling systems for them has been dubbed. The main part of the research is devoted to the consideration of nutritional and detailed methods of rational cooling of turbogenerators based on the use of innovative environment protection technologies, namely metal hydride hydrogen storage technologies as an environmentally friendly alternative to motor fuel. It is shown that an alternative to the traditionally used devices for cooling of electric machines with hydrogen is the use of hydrides of intermetallic compounds to implement the working processes of thermosorption compressors, which is due to the ability of reversible hydrides of intermetallic compounds to repeatedly sorb and desorb hydrogen at significantly different pressures, the value of which is determined by the temperature potential of the thermal effect, i.e. thermochemical compression of hydrogen. The methods of calculating the parameters used in the designing such devices have been analyzed, and the method of determining the parameters of phase equilibria of hydrides of intermetallic compounds has been suggested.
