POSSIBILITY OF USE OF HYDROGEN AND OXYGEN FOR PERFECTING CYCLE OF STEAM TURBINE PLANTS

Abstract

A perfected thermodynamic cycle of modified steam turbine plant is considered. In this cycle the mean temperature of heat supply, and therefore thermal efficiency, is higher, than in ordinary cycle. This is achieved by mixing of steam before turbine with products of combustion of hydrogen in oxygen and further maintaining initial temperature of working substance during major part of expansion. Calculations, carried out on example of powerful contemporary plant K-1200-240, shows possibility of increase of thermal efficiency by 20,3 % (from 53,3 to 64,1 %), and effective efficiency by 18,8 % (from 47,4 to 56,3 %).
