  • Coal Combustion

    The Centre has conducted numerous pilot scale evaluations on a large number of other coals (in excess of 400) from over thirteen countries. Coal evaluations focus on optimising process efficiency and assessing the effect of coal properties on the combustion performance of coals in industrial appliions, principally pulverised coalfired power plant boilers. Testwork has been undertaken on ...

  • Rethinking Burnout: When Self Care Is Not the Cure

    When we tie selfcare to burnout, it suggests that the coal mine doesn't need to be safer, employees just need to wear better protective gear. Indeed, the main causes of burnout are tied to work and inevitably, won't be fixed with more selfcare.
