  • Is `clean` coal possible?

    VANCOUVER, April 18, 2007 (GLOBE-Net) - Coal is the world’s most commonly used fuel to produce electrical energy, and will continue as such for some time. Yet it is one of the ’dirtiest’ of all fossil fuels. It is a major source of toxic air pollutants and the leading source of energy-related greenhouse gas emissions. Many believe ’clean coal’ technologies will improve the energy efficiency of ...

  • A novel approach for modelling of NOx emission reduction in a tangentially fired coal boiler

    In this research paper, predictive modelling of NOx emission of a 210 MW capacity pulverised coal–fired boiler and combustion parameter optimisation to reduce NOx emission in flue gas is proposed. The effects of oxygen concentration in flue gas, coal properties, coal flow, boiler load, air distribution scheme, flue gas outlet temperature and nozzle tilt were studied. The data collected from ...

  • Integrated process control for recirculating cooling water treatment in the coal chemical industry

    This work focused on the integrated process of the recirculating cooling water (RCW) treatment to achieve approximate zero emission in the coal chemical industry. The benefits of fractional and comprehensive RCW treatment were quantified and qualified by using a water and mass balance approach. Limits of cycle of concentrations and some encountered bottlenecks were used to ascertain set target ...

  • Recycling of coal seam gas-associated water using vacuum membrane distillation

    Coal seam gas-associated water (CSGAW), which is a by-product of coal seam gas (CSG) production typically contains significant amounts of salts and has potential environmental issues. In this study, we optimized a bench-scale vacuum membrane distillation (VMD) process with flat-sheet hydrophobic polytetrafluoroethylene (PTFE) membranes for the treatment of synthetic CSGAW (conductivity = 15 ...

  • Utilisation of Methane to Generate Electricity: BHP Appin and Tower Collieries

    Background BHP Collieries Division operates five underground coal mines in and around the Illawarra region of NSW. They include the Appin and Tower mines which are situated north-west of Wollongong and some 75 kilometres from Sydney. These two mines produce around 3.5 million tonnes of coal per year which is primarily used for domestic steel making. Some coking and energy coal is also ...


  • Modelling food web structure and selenium biomagnification in Lake Macquarie, NSW‐ Australia, using stable carbon and nitrogen isotopes

    As a consequence of coal‐fired power station operations, elevated selenium concentrations have been reported in the sediments and biota of Lake Macquarie (NSW, Australia). In the present study, we applied an ecosystem‐scale model to determine how selenium in a seagrass food web is processed from sediments and water through diet to predators, using stable isotopes (δ13C and δ 15N) to establish ...

  • Policy uncertainty puts UK at risk of missing carbon targets

    New report warns the government must set a clear policy direction to attract the investment needed for a low carbon economy. Recurrent policy uncertainty could mean the UK fails to attract the estimated £150bn of investment needed to build a low carbon infrastructure over the next 20 years. This is the conclusion published in a new survey today by the CBI and Accenture entitled: ...
