  • Characterisation of LD slag of Bokaro Steel Plant and its feasibility study of manufacturing commercial 'fly ash–LD slag' bricks

    The aim of this study is to couple several analytical techniques in order to carefully undertake physical, chemical and mineralogical characterisations of LD steel slag to determine its feasible utilisation in commercial brick manufacturing. The characterisation results of LD slag showed that the pH and electrical conductivity of the samples were very high indicating high percentage of lime ...

  • Application of leachate pollution indices for assessment of leachate pollution potential of landfills (a case study of an unlined landfill with lime sludge and fly ash)

    Leachates from unlined landfills cause environmental degradation and health hazards due to resultant ground water pollution. Their pollution potential can be measured on a comparative scale using leachate pollution index (LPI). The selection of index involves 18 pollution parameters, their weightages and the sub–index values. The concentrations of pollutants are obtained from toxicity ...

  • 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 ...

  • Chemical exergy analysis of Afşin–Elbistan lignite and its effects on the thermal power plant exergy efficiency

    In this study, the chemical exergy of low profile industrial lignite has been studied through a case study at the 1440 MW Afşin–Elbistan B lignite–fired power plant. Chemical exergy methods in the literature were applied to design lignite to investigate results on the exergy efficiency of the power plant for different power rates. The ASTM standard and well known methods have been compared by ...

  • Biochar: forgotten agricultural nostrum

    What is biochar?  The new multifunctional products are in good request nowadays. One of such innovations is Biochar. This type of charcoal is manufactured using the low-temperature continuous pyrolysis equipment. The raw material for the recycling process is biomass (agricultural and other biological waste). Biochar origins (Terra ...

  • Pyrolysis

    Introduction: Pyrolysis is formally defined as chemical decomposition induced in organic materials by heat in the absence of oxygen. In practice, it is not possible to achieve a completely oxygen-free atmosphere; actual pyrolytic systems are operated with less than stoichiometric quantities of oxygen. Because some oxygen will be present in any pyrolytic system, nominal oxidation will occur. If ...

  • Market Demand for Rice Husk Pellets is Increasing

    Rice husk pellet is a kind of biomass material pellet. It is made of rice husk or rice hull, which is the outer layer of the paddy grain. Rice husk is with deficiencies of soft, light and low in caloricity. After pressed by the biofuel pellet mill, ...

  • 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, ...

  • Biomass energy outlook

    Over the last three or four weeks, my newsletter, Burning Bio News, has been oddly extreme. Timothy Searchinger, Princeton University, is churning out more antibiofuel hearsay. Dennis Avery, Hudson Institute, was in the news again putting a counter-spin on climate change. The U.S.EPA released its proposed rule for regulation of Greenhouse Gases (GHG) that includes industrial facilities that emit ...
