  • Cenospheres - Case Study

    The problem: A cenosphere is a lightweight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas, typically produced as a byproduct of coal combustion at thermal power plants. On average 0.5% of the fly ash generated in a coal fired power station boiler are Cenospheres. When fly ash is wet discharged in to ash ponds/lagoons cenospheres float on ...

  • Methylmercury in mosquitoes around a large coal‐fired power plant in Central Ohio

    Emissions from coal‐fired power plants are the major anthropogenic source of mercury (Hg) in the environment. Because emitted Hg can be deposited near the source, concerns arise about the effects of coal‐burning facilities on levels of toxic methylmercury (MeHg) in biota near such sources. We investigated the potential impact of a large Hg‐emitting (450 kg in 2005) coal‐fired power station in ...

  • Cleaning biogas with bacteria

    Organic materials added to an anaerobic digester commonly contain sulphur components. During the anaerobic digestion process, the sulphur is converted into hydrogen sulphide (H2S), which is absorbed by the biogas. When the biogas produced in an AD plant goes on to be combusted in a gas engine or boiler, the H2S will give off sulphur dioxide (SO2) and sulphuric acid ...

  • Reasons for efficiency: Plain as the smudge on your face

    Remember soot? A long time ago, before global warming, getting rid of soot was considered a good reason to make our energy supply cleaner and more efficient. These small dirty particles, created from auto and power plant combustion, discolor walls and do worse to our lungs. Their harm is immediate, yet we seem to have forgotten this, as we’ve become consumed in energy debate about future worries. ...

  • Co-firing Solid Recovered Fuels (SRFs) with brown coal in large-scale pulverised fuel power plants – a simulation approach

    The results of the numerical simulations performed in a pulverised fuel boiler co-firing coal and Solid Recovered Fuels (SRFs) are presented. SRFs are initially modelled as a mixture of two different fractions (biogenic and plastic) and further simplifications are proposed to save computational expenses. The SRF submodels are validated with available data obtained from a laboratory-scale ...

  • Better combustion airflow monitoring at the Hunan Yiyang power plant

    China has experienced tremendous growth in electricity demand over the past two decades. Coal-fired plant construction has exploded in the country to meet its seemingly insatiable appetite for electricity. Because most power plants in China use coal as fuel, it is imperative that new coal-fired plants be as clean and efficient as possible. This demand for cleaner plants has led to new and ...
