  • A new Rankine cycle for hydrogen-fired power generation plants and its exergetic efficiency

    A novel power generation cycle is proposed in this paper taking hydrogen as fuel and using steam generated by hydrogen firing as working fluid. The progress of the development work and side issues such as the application of hydrogen combustion turbines to environmentally clean fossil fuel power plants for early commercialisation of the system are reviewed. We propose the hydrogen-fired Rankine ...

  • Quantifying Combined Heat and Power (CHP) activity

    In CHP plants without heat rejection facilities power, output is complementary to the recovery of heat, and all activity is cogeneration. CHP plants with heat rejection facilities can operate a mix of cogeneration and condensing activities. Quantifying the energy flows of both activities properly requires knowledge of the design power-to-heat ratios of the CHP processes (steam and gas turbines, ...

  • Gas turbine emissions and environmental impact of efficiency boosting techniques

    In this paper, environmental impact of gas turbine power generation equipment is reviewed and emissions sources are discussed. The types of pollutants in simple cycle gas turbine power plants and the associated air quality problems are compiled. Then, airborne pollutants which are generated in the combustion turbines are described and factors affecting emission formation are discussed. Also, the ...

  • Combined Heat and Power (CHP) essentials

    'CHP essentials' introduces the concept of power and heat 'production possibility sets', starting at the cradle of CHP, i.e., the thermal power generation plant. The latter always occasions 'fatal' heat that is either recovered (the 'merit' of CHP) or wasted (condensing). This split paves the way to defining the production possibility sets of CHP plants, shown for steam turbines, internal ...

  • Sensitivity analysis and thermo-economic optimisation of Steam Injected Gas Turbine cycle design parameters

    The purpose of the present work is to apply thermo-economic concepts to a Steam Injected Gas Turbine (STIG) electricity generation system and optimise it to indicate its economical advantages over a simple gas turbine. The system incorporates a combustion chamber, gas turbine, a compressor and a Heat Recovery Steam Generator (HRSG). A detailed sensitivity analysis was also performed to examine ...

  • A cost–effective backward Lagrangian method for simulation of pollutant formation in gas turbine combustors by post–processing of complex 3D calculations

    A backward Lagrangian Monte Carlo modelling is proposed to calculate by post–processing the PDF of the thermo–chemical parameters of complex turbulent reactive flows simulated with a simple turbulent combustion model. PDF's of minor species such as pollutant species (NOx, soot, unburnt hydrocarbons...) can be easily obtained as long as these species have no significant influence on the main ...

  • EU regulation of combustion plant - A power industry perspective

    Any installation that contains combustion plant with an aggregated thermal input greater than 50 MW is regulated under the Industrial Emissions Directive (IED) which requires that Best Available Techniques are applied to emissions control. Individual plant with a thermal input greater than 50 MW are regarded as Large Combustion Plant and additional provisions apply, including mandatory Emission ...

  • Thermodynamic analysis of an integrated gasification combined cycle power plant: effect of nitrogen supply on system performance

    A comprehensive thermodynamic analysis of a conceptual integrated coal gasification combined cycle power plant is presented. Energy and exergy efficiencies and exergy destructions of each sub–unit are calculated. The effect of nitrogen, which is supplied from the Air Separation Unit (ASU) of the gasification unit to the combustion chamber of the gas turbine (GT) cycle, on system performance is ...

  • Los Angeles County Sanitation Districts: Siloxane Removal

    Los Angeles County Sanitation Districts have long been involved with recovering landfill and digester gas for energy to power turbines and internal combustion engines. Their experience led them to identify performance issues associated with these gases. One particular challenge is siloxanes. Cyclic organic silicon monomers (siloxanes) used in the manufacture of personal hygiene, health care and ...

  • CFD based exploration of the dry-low-NOx hydrogen micromix combustion technology at increased energy densities

    Abstract Combined with the use of renewable energy sources for its production, hydrogen represents a possible alternative gas turbine fuel within future low emission power generation. Due to the large difference in the physical properties of hydrogen compared to other fuels such as natural gas, well established gas turbine combustion systems cannot be directly applied for ...

  • Comparative study of steam injection effects on operation of gas turbine cycles

    In the present work, gas turbine cycles are modified with steam injection between the combustion chamber exit and the gas turbine inlet. Heat recovery steam generators, utilising the exhaust gases, provide these cycles with the injected steam at saturated vapour. The irreversibility of the different composing units of the cycles and the variation of gas properties owing to steam injection as well ...

  • Is `Dark Fuel` the same as `Bad Fuel` and can I still use it?

    Algae-X FAQ’sIs 'Dark Fuel' the same as 'Bad Fuel' and can I still use it?This is a question many of us have asked more than once. And what we really want to know is: 'Will the stuff damage my engines?' Engines are expensive, ruining an engine is costly and operating an engine on 'bad fuel' is not wise. We all know that most engine failures start in the fuel tank. When all mechanical parts ...

  • Exergy analysis of the steam-injected gas turbine

    In this paper, the effect of steam injection in the combustion chamber on the exergy efficiency of a gas turbine was investigated. Cycle exergy efficiency, net power output and exergy destruction have been calculated for different mass flow rates and temperature of the injected steam. The range of variation of the mass flow rate was between 0 and 5.24% of the design air flow rate, and the ...
