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 volatility of elements was correlated with the fuel bed temperature. The leaching of heavy metals out of the bottom ashes was not affected.
