Pelletizing and Combustion Behaviors of Wood Waste with Additives Mixing

Pelletizing and combustion behaviors of wood waste
with and without additive addition were investigated in this
study. It was found that the wood waste pellets have a high
potential for slag formation during combustion and can cause
operational problems. With additives addition, no significant
changes were observed regarding mechanical properties of the
wood waste pellets. Sewage sludge addition was found to have
positive effects on NO_x and CO emissions during combustion.
Both sewage sludge and marble sludge addition have evident
influence on slag formation during combustion. Sewage sludge
addition reduced the formed slag amount and sizes, and therefore
improved the boiler operation. Marble sludge eliminated the slag
formation during the wood waste pellets combustion.
