  • Experience on coal reburn in a utility boiler

    Reburning is an in-furnace combustion modification technology for the reduction of NOx. By staging the introduction of the fuel, an environment is created where NOx generated by the combustion of the main fuel supply is subsequently consumed by the hydrocarbon radicals arising from the reburn fuel under reducing conditions. ENEL has retrofitted unit No. 4 of Vado ...

  • 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 ...

  • Tuning Your Boiler for Fuel Savings – Out with the Old in with the New Technology

    The USA has about 811,000 MW of installed generation and over 52% of our Electric power is produced by aging coal fired power plants. The average utility boiler furnace was designed about 30-40 years ago. According to DOE records, the average boiler in 1974 was fired with 80% bituminous coal. Now, western PRB coal is much more prevalent and represents about 50% of total coal ...

  • Water impounded bottom ash collection systems

    Ash is a by-product of the combustion process in power generating stations that burn coal as a primary fuel. Combustion takes place in a boiler that is actually a large open furnace. The walls of the furnace are lined with pipes that carry water to produce steam that powers a turbine generator. Ash is present in two forms: 1) Fly-ash, a lighter material that exits the boiler in the flue-gas ...
