  • End-of-life Tires as an Alternative Fuel (TDF) in Cement Kilns: Now Easier than Ever!

    End-of-life tires are a challenging type of waste since they are difficult to shred and are expensive to treat and get rid of. However, tire derived fuel TDF is an extremely good alternative to the traditional fuels used in cement kilns, like oil, coal, and petroleum coke. The following blog presents a solution and explains how TDF can be used for heating cement kilns. ...

  • Sample preparation for the analysis of secondary fuel in cement plants

    Secondary fuel can be a very inhomogeneous sample, containing all types of polymers, paper, wood and low fractions of metal. Also recycled wood or parts of automobile tires might be used as secondary fuel. Before using it as fuel in the production of cement, several chemical analyses are necessary as quality control. Cement is made by heating limestone (calcium carbonate), with small quantities ...

  • Municipal solid waste: alternative source of energy to the cement kilns in the state of Madhya Pradesh, India

    Rapid urbanisation has resulted in large–scale municipal solid waste (MSW) generation in India. Scientific and environment friendly disposal of MSW is a challenge for the municipal local bodies. A survey has been conducted regarding municipal solid waste generation from 342 local bodies in the State of Madhya Pradesh. Total generation of the MSW in the State is estimated around 4,500 MT/day ...

  • Practical guide to alternative fuel utilisation

    Today’s business environment for the cement producers is becoming more challenging. Rising production costs and environmental regulations are only two of the main limiting factors. Therefore the cement industry is using alternative fuels. In most cement kiln processes today, the conventional fuels (primary fuels) are gas, fuel oil, various coals and petcoke. The required calorific values can be ...

  • Tire Derived Fuel (TDF)

    Tire derived fuel (TDF) is a fuel derived from waste tires of all kinds. TDF is a major use for scrap or waste ...

  • The Future of Secondary Materials as Fuel

    Many questions related to the regulatory status of facilities that use secondary materials as alternative fuels are anticipated to be answered in 2010.  In simple terms, if a combustion source uses a secondary material that is characterized as solid waste as an alternative fuel, then that source could be subject to a Clean Air Act (CAA) Section 129 standard.  If the same source used a ...

  • Study Charts a Future for Waste-Derived Fuels

    Pointers to possible future EU policy initiatives to give co-incineration facilities burning waste-derived fuels a strategic role in waste management have emerged in a study for the European Commission.1 The report suggests a policy focus on promoting source separation of municipal wastes, active discouragement of mass burn incinerators, and a levelling of the regulatory playing-field for ...

  • Waste incineration in cement plants: constraints and development opportunities (a French-German comparison)

    Is it possible to reconcile economic and ecological concerns? This article examines, through a French-German comparison, the case of obtaining a calorific value for wastes used as substitute fuels in cement kilns. On the one hand, this new strategy for obtaining needed inputs offers to the cement industry an economic opportunity for lowering production costs (the main determinant of ...

  • Use of process analyzers in cement plants solutions from Siemens – Case Study

    Cement is a hydraulic binding agent to produce concrete. Due in part to the fast growth of the Asian economies, world consumption of cement is currently growing at an annual rate of 8%. Therefore, cement production is expanding and, at the same time, production processes need to be optimized to ensure maximum efficiency. In this context, process analytics plays an important role: It determines ...

  • A Sustainable Use for Dried Biosolids

    Lehigh Cement Company has conducted preliminary and in depth testing of Class A dried biosolids (DBS) as a fuel replacement in our cement kiln at Union Bridge, Maryland. Lehigh’s parent company, Heidelberg Cement, has been using DBS in European cement kilns for several years. These programs have proved the safety and environmental soundness of this concept. Lehigh’s ongoing development of these ...
