摘要
Seven wood burning facilities were analyzed for their emissions of PCDD/F and other parameters while th input was varied. PCDD/F emission concentrations ranged from 0.004 to 9.820 ng l-TEQ/Nm(3), with the majority of values > 0.1 ng l-TEQ/Nm(3), even in the input was untreated wood. Highest concentrations occurred after addition of halogenated materials (NH4Cl hardened or PVC coated plywood) to the input. Using typical input materials, facilities with smaller thermal capacity (< 1 MW) showed emission freights ranging from 0.03 to 0.4 mu g l-TEQ/h, while the large ones (> 1 MW) emitted 0.07 to 0.5 mu g l-TEQ/h. Using treated input materials, emission freights of smaller facilities reached 1.6 mu g l-TEQ/h, while the large plants released up to 7.2 mu g l-TEQ/h.
