  • Flame dynamics in sub-millimetre combustors

    This paper describes experimental observations of flame dynamics within an alumina non-premixed combustor with a sub-millimetre (0.75 mm) minimum size. These flame dynamics occur within a total combustor volume of 130 mm and are imaged through a sapphire window. The confined flames are surveyed using visual still-frames, high-speed flame imaging, measurement of external wall temperatures, and ...

  • Application of reactor net models for the simulation of gas-turbine combustor emissions

    The work deals with the evaluation of applicability of reactor net models and different reaction mechanisms for the predictions of emission characteristics of aero-engine combustors operating both in diffusion and in homogeneous burning modes. It is shown that the accuracy of the calculations of emission indices for NO x , CO and unburned hydrocarbons (UHC) is dependent strongly on the applied ...

  • 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 ...

  • Exergetic and exergo–economic analysis of a turboprop engine: a case study for CT7–9C

    The turboprop engine has played an important role in short haul commuter and military transport aircraft where high speed is not critical. It may provide the aviation sector with one of the most significant means of achieving reduced operating costs through reductions in fuel consumption. This paper deals with exergo–economic analysis of a modern turboprop engine (CT7–9C) with a free power ...

  • Energy and exergy analysis of a gas turbine power plant in Algeria

    An exergy analysis of a twin ABB GT13E2 Gas Turbines (GTs) power plant (2 ? 146.2 MW) is presented in this paper. This plant is running since 2004 at F'Krina in the northeastern part of Algeria. The analysis was performed by the flow-sheet programme, 'Cycle-Tempo'. At off-design load (83%), the plant and its apparatus conserve nearly the same design load performances. However, the performance of ...

  • NOx formation by steam injection using detailed chemical kinetics

    In order to improve thermal efficiency of gas turbine system and better control NOx emission, the injection of steam into a gas turbine combustor has been employed. This study has used both chemical equilibrium calculations and the counterflow diffusion flame calculations of methane-air flame aiming at the elucidation of the NOx reduction mechanism due to the steam injection. The influence of the ...

  • Technical and economic evaluation and feasibility study of biomass energy

    The urgent need for the reduction of harmful environmental impact during energy production necessitates research for efficient, economically feasible energy production processes. The wide spreading of energy coming from renewable energy sources with low or zero emission levels, such as wind energy, solar energy, hydro-energy and biomass, is the most promising solution to the problem. This study ...

  • Computational study of a diagonal channel Magnetohydrodynamic power generation

    This paper studies the performance of a diagonal channel Magnetohydrodynamic (MHD) power generation. This system includes a diagonal conducting wall MHD generator. As a model of channel, we use a scramjet-driven MHD generator where the MHD generator is directly integrated into the propulsion system. The channel specification is 59.28 cm in length. The working plasma for the power system is ...

  • 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 ...

  • Case study - ABUTEC’s medium temperature flare burns canning plant biogas

    A Northumberland, Pa.-based canning plant recently contacted ABUTEC, through ADI System Inc., for help combusting the biogases created during the canning process. During this process, foods that are being prepared for canning create biogases that are used in power generation for the local facility. Excess gases that are not used by the gensets are typically vented into atmosphere, which can ...


  • Tech Note: Flare Gas Measurement Innovation; Retain Flow Metering Accuracy Even if Gas Composition Changes

    It’s a fact oil wells almost always produce natural gas along with the petroleum. Nine times out of ten, the excess gas (typically hydrocarbons) is flared off or simply vented as-is during upset conditions in the process. The environmental impacts of “flaring” this excess gas into our atmosphere has resulted in government regulations like 40 CFR Part 60 Subpart OOOO (also ...

  • Plasma gasification and vitrification of ash – conversion of ash into glass-like products and syngas

    The Plasma Gasification and Vitrification of Ash (PGVA) system is a patented process that uses energy generated by plasma arcs along with the controlled addition of small amounts of air and steam to convert the organic portion of ash into a synthesis gas (gasification) and the inorganic portion into a glassy rock (vitrification). The vitrification of the ash’s inorganic portion ...
