The emission characteristic of PAHs during coal and sewage sludge co-combustion in a drop tube furnace
The emission characteristic of Polycyclic Aromatic Hydrocarbons,(PAHs) during coal and sewage sludge cocombustion was performed in a laboratory-scale drop tube furnace.The experimental results demonstrated that the mass percentage of sewage sludge had an important impact on PAHs emission during coal and sewage sludge co-combustion.In generally,the two-ring and five-ring PAHs concentrations decrease as the mass percentage of sewage sludge increase from 0% to 100%.Moreover,it was also found that PAHs from sewage sludge mono-combustion was dominated by the threering and four-ring PAHs.As for the coal monocombustion,the four-ring and five-ring PAHs was the principal components.Meanwhile,the five-rings PAHs was the main contribution for the toxic equivalent (TEQ) concentration during coal and sewage sludge cocombustion.The experiment results also indicated that coal and sewage sludge co-combustion was beneficial to suppress the PAHs TEQ concentration.
