  • Improve Boiler Efficiency

    In many chemical plants, the electricity the plant uses is derived from a natural gas power plant or a co-generation plant burning waste gas streams. In large boilers (Figure 1), power plants bring together air and fuel (natural gas, waste gas, oil or coal) for combustion, which creates heat. The heat boils the water, creating steam. The steam runs through a turbine, which causes the turbine to ...

  • AMETEK Land - World Coal - Beat the Heat

    Between the time a piece of coal is dug out of the ground and is burned in a power plant boiler, it has been through many stages of transportation and storage. One of the advantages of coal as a fuel for power generation is the ability to store substantial quantities on site. This provides a strategic buffer of at least one month's fuel supply, which can be valuable if there is a short- or ...

  • Cleaning of Dukki (Baluchistan) coal by oil agglomeration process

    Cleaning of coal fines by oil agglomeration is an efficient technique by which an appreciable recovery of combustible matter and significant reduction in ash forming minerals are possible. In this study, oil agglomeration process has been employed to clean indigenous coal under the influence of parameters such as oil type, particle size and the pH value of aqueous medium. As agglomerant, castor ...

  • Selenium bioaccumulation in fish exposed to coal ash at the Tennessee Valley Authority Kingston spill site

    In December 2008, 4.1 million m3 of coal ash were released into the Emory and Clinch Rivers by the Tennessee Valley Authority (TVA) Kingston Fossil Plant. Coal ash contains several contaminants, including the bioaccumulative metalloid selenium (Se). Because Se is predominantly accumulated in aquatic organisms through dietary, rather than aqueous exposure, tissue‐based toxicity thresholds for ...
