  • Power augmentation of PGE Gorzow's gas turbine by steam injection - thermodynamic overview

    Publikacja

    - Rynek Energii - 2012

    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...

  • On energy, exergy, and environmental aspects of a combined gas-steam cycle for heat and power generation undergoing a process of retrofitting by steam injection

    Publikacja

    - ENERGY CONVERSION AND MANAGEMENT - 2019

    The paper presents a study of retrofitting of a combined heat and power (CHP) plant aimed to increase the electric to heating power ratio. The modification would involve diverting part of the steam to the gas turbine, instead of letting it go to the steam turbine, using injection technique into a combustion chamber. Therefore, two potential retrofitting approaches are analyzed: steam injection gas turbine (STIGT) and combined steam...

    - Transactions of the Institute of Fluid-Flow Machinery - 2013

    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...

    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...

  • A study of a compact high-efficiency zero-emission power plant with oxy-fuel combustion

    Publikacja

    - 2019

    This paper discusses the application of global trends in gas cycles technology using oxy-fuel combustion. This is followed by a demonstration of a design solution for a new cycle with two enhanced energy-converting devices, namely a wet combustion chamber and a spray-ejector condenser. The proposed gas and steam cycle unit is contained within a single turbine, whose benefits combine those offered by gas turbines (high inlet temperatures)...
