| 中文摘要 | At present more and more countries and areas use incineration to process MSW, due to its unique characteristic in cobage reduce, detoxification and resource use. But smoke pollution will happen at improper incineration condition, such as NOx. This paper took the waste rubber and waste paper as the subject investigated to carry out pyrolysis experiment and incineration experiment and the formation of NOx precursors is investigated in this process. Firstly, pyrolysis experitment of the waste rubber and the paper was carried out in tubular furnace, and the effect of pyrolysis temperature and heating rate et. on the formation of NOx precursors was investigated. The results show that the waste paper releases more NH3 in pyrolysis than the waste rubber. The emission of HCN and NH3 from the waste rubber and waste paper in pyrolysis rised as the temperature rised. The increase of heating rate help to suppress the formation of NH3, however, to the formation ot HCN, it happens only in low pyrolysis temperature, and in high pyrolysis temperature, its inhibit function is small. Secondly, combustion experiment was carried out in tubular furnace, and the effect of reaction temperation and heating rate et. on the formation of NOx precursors was investigated. It shows that the release temperature of NOx precursors in combustion is obviously lower than that of pyrolysis. Even at the maximum reaction temperature during the pyrolysis experiment, the emission of the HCN and NH3 is by far lower than that at 700 degree in combustion. The existing oxygen promotes the breakage of the more stable nitrogen heterocyclic ring, which increases productivity of the HCN and NH3. HCN and NH3 was oxidized to NOx at higher temperature. The temperature at which the productivity of the HCN and NH3 reach to maximum value in combustion is different because of different raw materials. |
