Filtering probes Since flue gases contain dust of approximately 0 1 g Nm in general sampling tubes get clogged unless dust is removed from sampling probes Filters require maintenance Filtering probes generally are mounted at heights where a high scaffolding is exposed to the weather and maintenance is very difficult compared to equipment installed on the ground For this reason making a filtering probe with maintenance free construction is the most critical point for stack gas analyzer The structure of the Type F filtering probe is shown in the figure below A 20 um 304 SS wire net is used for a filter element see specifications below The Type M2E filtering probe can cover up to 0 5 g Nm of dust and uses a 5 um 316 SS filter element Table 2 6 Kind of Filtering Probe Name Type F Type M1E Type M2E Filtering Probe Filtering Probe Filtering Probe Part number K9718VC K9219ED K9718VE Operating o op x op x temperature 150 to 400 C 150 to 700 C 2 150 to 700 C 2 Probe material 304 SS 304 SS 316 SS Filter 304 SS 304 SS 316 SS 20 um 20 um 5 um Position of filter Inside stack Outside stack Outside stack Method for heating None Electricity at approx Electricity at approx filter 80 VA 1 130 VA 1 Flange material JIS 5K 80 RF JIS 5K 80 FF JIS 10K 50 FF 304 SS Equ 304 SS Equ 304 SS Equ Insertion length 700 mm 700 mm 1000 mm Weight Approx 5 kg Approx 11 kg Approx 15 kg F
