为了得到燃煤电厂掺烧城市污泥后的燃烧、结渣以及污染物排放特性,在自建一维沉降炉中,开展了5个不同掺混比例(0、5%、10%、15%、20%)下的混燃试验,并参照《火电厂大气污染物排放标准》(GB 13223—2011)等规定对不同工况下的样品、数据进行取样和测量。结果表明,随着污泥掺烧量增加,炉膛温度呈下降趋势,掺混比例达到20%时,炉膛顶部温度下降40℃左右;随着污泥掺烧比例增加,锅炉结渣倾向加重,燃烧生成的灰样主要成分为K-Al-Si和K-Ca-Si复合盐类;随着掺烧比例的提高,NOx的排放量呈现先增加后降低的趋势,SO_(2)的排放量逐渐降低;5种掺混比例下烟气中的二噁英与飞灰中的重金属含量分别满足《燃煤耦合污泥电厂大气污染物排放标准》(DB 31/1291—2021)与《农用粉煤灰中污染物控制标准》(GB 8173—87)要求;与纯燃煤相比,掺烧20%污泥时,可减少CO_(2)排放约0.34%。燃煤锅炉掺烧城市污泥可作为双碳战略下高效节能降碳的一种选择。

The resonant frequencies of the excited surface waves on a metal hole array with respect to the incident angle were studied in the terahertz *** experimental and theoretical results demonstrate that the resonant peak of surface wave excitation splits into two when transmitted through a metal hole array *** high-order mode with resonant frequency above the cutoff frequency fc(plasma frequency effect)has a shorter attenuation length than that of the low-order mode whose resonant frequency is below *** reason is that the high-order mode is a coupled mode consisting of surface wave and hole modes,while the low-order mode is just an excited surface wave(which can be considered as the spoof surface plasmons).Our investigation may open a door to distinguish the spoof surface plasmons and the coupled modes of surface waves and hole modes.
