  • How fire can be tamed

    Combustion dies at the interface between breathable air and macroscopic pieces of certain involatile fuels. If fed only them, in a compressed oxygen chamber, it makes an almost sunlike flame that cannot run wild. If upon dilution to manageable coolness the ash drops to the chamber bottom, and from there can be removed without the diluent, true harnessbrokenness is possible. Excess oxygen can be ...

  • Legal lookout: EPA responds to coal ash release

    Once again, it took a major catastrophe to wake up industry and regulators to a problem that should have been addressed long ago. Dec. 22, 2008, was a nightmare for federal and state regulators, electrical utilities, and most particularly the residents of Kingston, Tenn. On this day, approximately 5.4 million cubic yards (or 1.1 billion gallons) of coal ash from the Tennessee Valley Authority ...

  • Cement - The one and only in Estonia

    Estonia is quite a small country and it also lacks good quality rock. However, in the northeast there are quality limestone deposits and also the only cement factory in the country. Today, Kunda Nordic Cement (KNC) follows proudly the tradition of cement production that started there in 1870. Now KNC belongs to the HeidelbergCement Group. Site, acquired recently by Kopar, has been a vital element ...

  • Case study - Fly ash for California’s Olivenhain dam

    The Olivenhain Dam will be the first roller compacted concrete (RCC) gravity dam in California and the tallest in North America. At 308 feet tall and 2,552 feet long, the dam used almost 1.5 million cubic yards of RCC and over 152,000 tons of fly ash. As the centerpiece of the San Diego County Water Authority (SDCWA) Emergency Storage Project, the dam is designed to survive a major earthquake and ...

  • American Electric Power Service Corp., Clinch River Power Plant, Cleveland, Virginia U.S.A.: Accelator® Solids Contact unit and Greenleaf Filter Control

    Problem Combined wastewater streams from ash tank overflow, boiler room sumps, cooling tower blowdown, seal and cooling water, and various plant drains exceeded current discharge limits for copper. The owner anticipated new NPDES permit limits to be further reduced to 9.3 ppb Copper. TSS reduction was also ...

  • 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 ...

  • Legal lookout: competing coal ash proposals

    Depending upon comments the EPA gathers, industry may have to or not have to close out their coal ash containment ponds within five years. On May 4, 2010, EPA issued its long-awaited proposal to manage coal ash – the byproduct of burning coal to generate power. The agency proposed two quite different approaches for regulating coal ash, somewhat to the consternation of critics, who had hoped ...

  • Biomass Pellet Fuel and Its Advantages

    With the continuous deterioration of the people's living environment, global warming topic has become a concern of people from all walks of people. It has been very important to the development of new energy. At present, our main fuel is oil and coal, these are non-renewable materials, and you'll never have again when we use them up. Therefore, many countries are in the research of new energy, ...

  • Measuring Gases Produced by Waste Gasification to Improve Control and Efficiency

    Waste gasification is a type of waste to energy process where waste material is used as a fuel to create heat, electricity or other chemical products. Specifically, in waste gasification, the waste material is decomposed in such a way to produce gaseous products, often known as syngas, a combination of hydrogen, carbon monoxide and some carbon dioxide.Conventional incineration uses heat and ...

  • Investigation of benefit of using coal wastes in cement production

    Waste disposal in coal preparation plants leads to serious environmental problems. These wastes usually contain about 20% carbon, and the composition of the remaining ash is similar to clay. Addition of these wastes to cement clinker raw material utilises carbon as a source of energy. In this investigation, the effect of addition of these waste materials to the raw materials used in cement ...

  • Impact of alkaline oxide on coal ash fusion temperature

    Ash fusion temperature (AFT) is an important index for coal gasification. A blend of fluxing agent with coal can decrease the AFT to meet the requirements of specific gasification process. Effect of alkaline oxide and silica alumina ratio on decreasing AFT is focused in this study. Simulation ash was used to investigate the effect of alkaline oxide on AFT. The experimental results showed that ...
