固定污染源排放管道細懸浮微粒(PM2.5)現況調查及污染管制計畫
| 中文摘要 | 本研究之主要目的包括：檢討目前PM2.5檢測方法之限制並提出修正方式、調查國內PM2.5排放現況、分析PM2.5控制技術與效能等，藉此以提出PM2.5防制設備建議以及評估排放標準與收費制度之可行性。 本計畫於實驗室利用微粒穿透率測試系統以及SO2產生系統，據以評估PM CEMS採樣系統之微粒損失及SO2對CPM採樣方法之影響。除了蒐集目前國內外PM2.5排放資料外，也針對國內電力業進行9次粒狀物採樣與化學成分分析，另蒐集國內外防制設備對PM2.5排放濃度之影響，並分析目前防制技術之可行性。此外，也參考國內之文獻，提出排放標準草案，做為未來管制參考，且評估徵收空污費的可行性。 抽取式PM CEMS採樣系統在粒徑2.5微米的微粒有超過15%損失，對於10微米之微粒則有超過95%的損失，建議在前方加設PM2.5分徑器降低採樣誤差。PM2.5稀釋分徑器能夠避免因水滴造成之誤差，200 ml的回收洗液約有95%的回收效率。本計畫也提出目前PM2.5採樣方法之限制與改善方案，未來將提出草案修正相關建議。PM2.5排放標準則建議可根據TPM濃度進行PM2.5/TPM比例上之調整，於新設之燃煤與燃氣電廠其係數為0.65與1，既有之電廠則為0.37。 | ||

Study of the measurement method and control strategy of fine particulate matter emissions from stationary sources
| 英文摘要 | The purposes of this study are to evaluate the restriction of the PM2.5 measuring method, propose the modified plan, survey the PM2.5 emission, recommend the PM2.5 APCD technology, and evaluated the possibility of the emission standard and fee. The particle transmission efficiency of PM CEMS was evaluated by the particle penetration test system and the effect of SO2 artifact was evaluated by the SO2 generation system. The PM 2.5 sampling data was collected from domestic and international research. 9 PM sampling and chemical analysis were conducted in this study as well. The best control stretagy for PM2.5 was analysed by collecting state-of-the-art technologies. The PM2.5 emission standard and fee were proposed by considering of domestic emission condition and control technology. The sampling tube of the extractive type PM CEMS had 15% and 95% lose at the particle size of 2.5 and 10 um respectively. Install the particle separator in front of the PM CEMS was recommended. The PM2.5 dilution separator was designed to avoid the bias caused by water droplet. The 200 ml of wash reagent can reach 95% recovery ratio. The modified plan for the PM2.5 was proposed and the draft recommendation will be summited in this study as well. The PM2.5 emission standard should be calculated by PM2.5/TPM factor. The recommended factor are 0.65 and 1 for new gas-fired and coal-fired power plant and 0.37 for old fire power plant. | ||
