Review of ways to increase efficiency of energy generation at TPP at the account of additional energy carriers

Abstract

The problem of increasing the efficiency of generation facilities through the use of additional energy carriers is considered. Presented are the modern achievements of ways to increase the efficiency of energy production at TPPs: 1) transition to super-critical parameters of steam and 2) multigeneration. Increasing the parameters of steam increases the energy efficiency of electricity production, and multigeneration allows to produce additional energy carriers (hydrogen, oxygen, compressed air, cold, etc.) due to the unclaimed capacity of the equipment used or the utilization of flows inside the generating facility. The additional energy carriers produced as a result of such processes can be centrally supplied to external consumers or used inside the production cycle, for example, to switch to super-critical steam parameters. The transition to over critical parameters is possible when using high-temperature over heaters or when using new boiler units.
