This paper describes the result of field measurements of nitrous oxide (N_2O) emission from fluidized bed sewage sludge incinerators. Continuous monitor of N_2O were done for 4 incinerators in 5-7 days for each incinerator. N_2O emission was changed with operation condition of incinerator and composition of sewage sludge. Generally, highest value was two times larger than lowest value. This results suggest that determination of N_2O emission factor by grab sampling may have low certainty. Determination of N_2O emission factor by a long term continuous monitor is required to make a good estimation of N_2O budget. N_2O emission was almost determined by the free board temperature in the incinerator. Emission factor obtained laid between 1500 〜 4700 g-N_2O/t- dry sludge. This value was much larger than the value published on "Good Practice Guidance and Uncertainty Management in National Greenhouse Gas Inventories" by IPCC.
