  • A quick guide to oil analysis for engine test applications

    Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

  • How conditions affect cookies and air pollution control solutions

    Chocolate chip cookies are one of my favorite treats. Butter, sugar, eggs, flour, vanilla, and, of course, chocolate chips. Combine the ingredients together and you get a delicious cookie. Somehow, using the same ingredients the cookies do not always turn out the same. Sometimes they are thinner and crispier. Other times, they are soft and chewy. After watching cooking shows, I have come to ...

  • CFD Analysis of Gas Cooling

    In many industrial processes, hot gas is cooled down due to the evaporation (boiling) of sprayed droplets. The effects of two different atomizer types, inner mixing air atomizing nozzles and flow back nozzles, on the cooling behavior inside a spray tower for a typical flue gas are discussed. The heat and mass transfer is computed using computational fluid dynamics (CFD). The interaction between ...

  • Exergetic analysis of gas turbine plants

    An exergetic analysis was performed for a 116-MW gas-turbine power plant. Mass and energy conservation laws were applied to each component of the system. Quantitative exergy balance for each component and for the whole system was considered. In this study, the exergy of a material stream is decomposed into thermal, mechanical and chemical exergy and an entropy-production flow. The effect of a ...

  • Exergy analysis of gas-turbine systems with high fogging compression

    Gas-turbine cycles with high fogging compression could offer enhanced efficiency and low complexity. Whereas compression power and heat rates decrease when small amounts of water (up to 2% of air flow by mass) are injected at the machine inlet, increased injection amounts could allow implementation of regeneration, further decreasing the heat rate. In this study, an exergy analysis is carried out ...

  • Sensitivity analysis of component efficiencies on performance of a gas turbine cogeneration system

    The performance of a 1000 kW gas-turbine cogeneration system was evaluated in terms of performance measures, such as net power, exergy efficiency of the system, and the unit costs of electricity and steam. The efficiencies of some components that have a significant affect on the performance were taken as physical variables. Sensitivity was evaluated by introducing parameters, defined as the ratio ...

  • Global solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Technical and economic analysis of gas-engine driven heat pump in China

    In this paper, the primary energy ratio and economic benefit of five different heating systems are analysed. The results show that the gas-engine heat pump system has the advantages of high primary energy efficiency and favours environmental protection in contrast to the other four heating systems. At the same time, to improve the economic benefit of the energy saving and environmental protection ...

  • Exergy analysis of Airlift Systems: experimental approach

    Airlift Systems (ALS) are widely used in various industrial applications. As the main part of the flow through ALS's upriser pipe, is formed by gas-liquid flow, the analysis of such systems will be accompanied by problems of two-phase flow modelling. Several effective variables are involved in ALS; thereupon comprehensive method is needed to consider these parameters. Exergy analysis can be ...

  • Satellite analysis and mesoscale behaviour of volcanic plumes and gas from Miyakejima, Japan

    Miyakejima plumes of ash-rich and vapour-rich clouds were detected well by the NOAA/AVHRR data, and the height of eruption cloud on 29 August 2000 was estimated reasonably using the brightness temperature at 11 µm of NOAA/AVHRR and the upper air data taking into account the effect of ash emissivity. We found two different mechanisms which bring the high concentration SO2 to the mainland of ...
