  In the paper, thermodynamic analysis of two modifications of a Brayton cycle into enhancement cycles with water/steam injection are discussed. The first one deals with a STIG modified system with both interstage compressed air cooling and air heating (heat regeneration) before combustion chamber. The second one, mainly devoted to higher steam/air ratio, is connected with separate steam production in a HRSG. The analysis has been...

  The impact of steam injection upon a gas turbine and a combined power plant performance has been investigated. This article describes and summarizes possibilities of modification for current gas turbine in PGE Gorzow power plant into the Cheng cycle. Our modification deals with a thermal cycle, in which steam produced in a heat recovery steam generator is injected into the gas turbine's combustion chamber. It has been proved that...

  Steam injection in gas turbines is interesting technology with good energetic and ecological properties of gas turbines. In these applications the heat of exhaust gases is used to produce steam, which is injected in the combustion chamber of a gas turbine. The steam injection increase the power and efficiency of the installation. there are some possibilities to increases the properties of STIG turbines, for example by meas of additional...
