Pellet fuels were manufactured from co-pelleting the mixture of pulverized municipal sewage sludge and wood sawdust.
The boiler efficiencies of pellet fuels are extremely high.
The secondary pollutant emissions are all lower than the legal limit.
The PCDD/Fs congener profiles for slag are different from that of other incineration processes.
Heavy metals distributed mainly into the slag with a few into the stack flue gas and fly ash.
