THE ACTUALITY OF REFUSAL FOR TURBOGENERATORS HYDROGEN COOLING

The possibility of refusal for powerful turbogenerators hydrogen cooling of electric power stations is substantiated. The advantages of a turbogenerators full air cooled in comparison with a turbogenerators hydrogen and hydrogen-water cooled are shown. The analysis for stored domestic and world experience of design and operation a large power unit turbogenerators with full air cooling is given. It is shown that modern level of technology, stored experience of operation and researches a power turbogenerators, the use more improved materials and cooling systems, a new design and technological solutions allows building high-power generators with full air cooling for ensuring fire and explosion safety of thermoelectric and nuclear power stations.
