  • Remediation of Abandoned Coal Mines Using Coal Combustion Products

    A slurry of mine water and coal combustion fluidized bed ash (FBA) was injected into an abandoned coal mine in Eastern Oklahoma in July 1997. Oil-field technology was used to inject 1.8 Gg (418 tons) of FBA through five wells in 15 hours. Alkaline minerals in the FBA neutralized acidity and imparted alkalinity to the mine water. Thus, this remediation method uses the waste from an industrial ...


  • Coal combustion products in Europe - sustainable raw materials for the construction industry

    The production of coal combustion products (CCPs) in all the European member states is estimated to be about 100 million tonnes. The utilisation of CCPs is well established in some European countries, based on long term experience and technical as well as environmental benefits. The CCPs are mainly utilised in the building material and construction industry as a replacement for natural resources. ...

  • Ammonium, nitrate, and total nitrogen determination in fly ash

    Fly ash is a by-product of the combustion of pulverized coal and is composed of small particles. The composition of the fly ash may vary considerably, however, all fly ashes contain substantial amounts of silicon dioxide (SiO2), aluminum oxide (Al2O3) and calcium oxide (CaO). Nowadays, air pollution control standards require a separation of flue gas before being released to the atmosphere. Fly ...

  • Why Are CHP Closing All Over The World?

    Burning of coal nowadays has become a big problem. The main reason for this is a rapid increase of mankind. So, China burns half of coal in the world. Since 2000 the share of coal in world energy production has increased from 25 to 30%, and the Chinese economy is responsible for 82% of this growth. In Beijing, it is customary to use ...

  • A process for synthesising polymeric ferric sulphate using sulphur dioxide from coal combustion

    We propose a process that uses sulphur dioxide from coal combustion as a raw material to synthesise polymeric ferric sulphate (PFS), a water treatment agent. The process uses sodium chlorate as an oxidant and ferrous sulphate as an absorbent. Sodium carbonate is used as the regulator of the polymerisation process. The major chemical mechanisms in this reaction system include oxidation, ...

  • Is `clean` coal possible?

    VANCOUVER, April 18, 2007 (GLOBE-Net) - Coal is the world’s most commonly used fuel to produce electrical energy, and will continue as such for some time. Yet it is one of the ’dirtiest’ of all fossil fuels. It is a major source of toxic air pollutants and the leading source of energy-related greenhouse gas emissions. Many believe ’clean coal’ technologies will improve the energy efficiency of ...

  • Combustible Dust: It Doesn’t Take Much

    A dust accumulation of 1/32 of an inch deep—about the thickness of a dime—covering just five percent of a room’s surface area doesn’t sound like much, but it’s enough to cause a catastrophic explosion, according to the National Fire Protection Association (NFPA). Although good engineering and safety practices to prevent dust explosions have existed for decades, there ...

  • EPA proposes revisions to GHG mandatory reporting rule for stationary combustion sources

    This summer, EPA proposed several updates and amendments to the GHG Mandatory Reporting Rule (40 CFR Part 98). This activity is consistent with EPA’s stated intention to issue amendments and re-propose subparts (i.e., those subparts that were initially reserved upon finalization of the rule last October) by the end of 2010. EPA’s published revisions in the Federal Register on June 15, ...

  • How to create qualitative fuel from water and coal: case study

    What is “coal-water fuel”?   Coal-water fuel (CWSF or CWS or CWF) is a fuel which consists of fine dispersed coal particles, water and plasticizing agent. This type of fuel is widely used as an alternative to gas and black oil on different heat generating facilities. The operational economy is the main of advantages ...
