  • Hurricane HR Cyclones to capture fine fly ash particulate enabling the use of wood waste fired thermal oil heater for Sonae Indústria - Case Study

    The company was forced to use a natural gas fired hot gas generator for drying fibre despite having the necessary amount of thermal energy available in the exhaust stream of a wood waste fired thermal oil heater. The problem of using the biomass thermal oil heater laid on the emission of fine burnt and unburnt particulate which were carried over with the dried fibre and finally deposited on the ...

  • Influence of Decreasing Heating Value on MSW Combustion

    Test runs in the TAMARA test facility to investigate the influence of decreasing lower heating value on the combustion of waste showed that the combustion quality could easily be kept constant at heating values exceeding 5 MJ/kg. The burnout of grate ashes and flue gas had slightly fallen off at lower heating values whereas the level of PCDD/F in the raw gas stayed constant in all tests. The ...

  • 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 ...
