  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...

  • Multidimensional modelling of the effect of engine load on various exergy terms in an indirect injection diesel engine

    In this investigation, the energy and exergy analyses are carried out in a Lister 8.1 IDI diesel engine for different loads (25%, 50%, 75% and full loads operation) at maximum torque engine speed (730 rpm). The energy analysis is done during a closed cycle using of a three dimensional CFD code. The results by this model for the pressure in cylinder at 50% and full load operations are compared ...

  • Studies on behaviour of a DI diesel engine fuelled with bio oil biodiesel emulsions

    This paper discusses the results on the use of Jatropha methyl ester (JME) - Wood pyrolysis oil (WPO) emulsion as an alternative fuel in a compression ignition (CI) engine. Three different emulsions were prepared by adding WPO in 5%, 10% and 15% by volume with JME 95%, 90% and 85% by volume respectively using a surfactant Span 20 at 4% on volume basis. The engine behaviour in terms of the ...

  • Greenstars portable monitoring for CHP and flares

    Greenstar’s award-winning KTK landfill site in Kilcullen, Co. Kildare, is unusual in Ireland in that it has three gas engines feeding electricity to the grid and two flares. In Ireland, while flaring is common, engines are not. The flares are run in tandem with engines so that if an engine is ramped down for repair or service, the flare ramps up automatically. All are supplied by 122 ...

  • US developments in the regulation of chemicals, pesticides and occupational safety

    The US Environmental Protection Agency released the 2006 Toxics Release Inventory (TRI) data back in February. The TRI, created under the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA), requires certain facilities to report annually on their chemical releases and other waste management activities to EPA and the states. In addition, the Pollution Prevention Act of 1990 (PPA) ...

  • Methanol blending is alternative fuel of the future

    The main objective of “alcohol fuel power” field is increase of fuel resources for transport by using right alternative  such as ethanol and methanol blending with gasoline, which unlike pure oil fuel, are characterized renewable and have unlimited sources of raw materials. Margin of oil (valuable hydrocarbonic raw materials for petrochemical productions) and also a power ...

  • Gas boiler load optimisation controls can rectify dry cycling and reduce energy costs by 25%

    Dry cycling of gas boilers can waste a great deal of energy, even when BMS optimisation is in use. Installing gas boiler load optimisation controls can reduce this waste and help boilers run more efficientlyBuilding engineers, energy and facilities managers tend to overlook that many gas boilers waste energy through dry cycling when they are not actively contributing to the building heating and ...

  • Rectify dry cycling of gas boilers and reduce energy costs by 25%

    Building engineers, energy and facilities managers tend to overlook that many gas boilers waste energy through dry cycling when they are not actively contributing to the building heating and hot water demand. It is often thought that existing building management systems (BMS) and building energy management systems (BEMS) are optimising the boilers to remove dry cycling. However, the BMS is ...

  • Total 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, ...

  • New NO2 air standards prove technically challenging

    On February 9, 2010, the U. S. Environmental Protection Agency (EPA) established a new National Ambient Air Quality Standard (NAAQS) for nitrogen dioxide (NO2). The new NO2 NAAQS is a one-hour standard set at 100 parts per billion (ppb), which is approximately 188 micrograms per cubic meter (μg/m3). Effective on April 12, 2010, the new one-hour standard is intended to protect against peak ...

  • Bio-SNG featured in energy world in February 2011

    The use of bio-fuels for heating and lighting pre-dates the use of fossil fuels by thousands of years. However, unlike with fossil fuels, a systematic knowledge of the challenges posed by solid bio-fuels is not as widely understood, a fact attributable to the exponential acceleration of fossil fuel usage as global demand increased during the industrial revolution. In the wake of this, producers ...
