Current through Register Vol. 56, No. 14, July 15, 2024
(a) The sampling train normally used by the Department is shown on page 1 of Appendix 1 and shall consist of the following:
1. A sampling nozzle (A) [FN*] made of stainless steel (316) and having a sharp, tapered leading edge. Its internal diameter shall be of an appropriate size to permit a sampling rate that is as close as possible to 0.75 CFM at isokinetic conditions;
2. A glass-lined stainless steel probe (B) * with a heating system capable of maintaining the temperature of the sample gas passing through it sufficiently high to prevent condensation of Water from occurring and a temperature sensor (T[1]) * to indicate the sample gas temperature;
3. A high-vacuum hose (C) * with a smooth, inert inner wall and with a heating system capable of maintaining the temperature of the sample gas passing through it sufficiently high to prevent condensation of water from occurring, and a temperature sensor (T[2]) * to indicate the sample gas temperature. In lieu of this hose, direct coupling of the probe (B) * and the glass cyclone and filter assembly (D[1] and D[2]) * may be used;
4. A sample collector consisting of a glass cyclone(D[1]) * followed by a glass fiber filter (Reeve-Angel 934AH **, MSA 1106BH ** or approved equivalent) in a glass holder (D[2]) *. The cyclone and filter assembly shall have a heating system (D) * capable of maintaining the temperature of the sample gas passing through it sufficiently high to prevent condensation of water from occurring, and a temperature sensor (T[3]) * to indicate the sample gas temperature. The use of the cyclone is optional when it is not necessary to prevent the filter from being overloaded by large particles;
5. A condenser system (E) * consisting of a Greenburg-Smith impinger (E[1]) * containing 100 ml. distilled water followed by a modified Greenburg-Smith impinger (E[2]) * (dry) for mist knockout, both immersed in an ice bath;
6. A drying tube (F) * containing Drierite ** or silica gel;
7. A hose (G) * capable of holding a vacuum of at least 15 inches of mercury;
8. A leak-free pump (H) * with coarse (H[1]) * and fine (H[2]) * flow control adjusters and vacuum gauge (P) *;
9. A dry gas test meter (I) * accurate within two per cent and temperature sensors (T[4]) * to indicate the sample gas inlet and outlet temperatures;
10. An orifice meter (J) * with an inclined manometer (M[2]) * as described in APCO Publication APTD-0581 (Reference 2);
11. A thermocouple (K) * attached to the probe (B) * its sensing portion adjacent to the sampling nozzle (A) * and equipped with a temperature sensor (T[5]) to indicate the stack gas temperature;
12. An "S" type pitot tube (L) [FN*] attached to the probe (B) * with its sensing portion adjacent to the nozzle and equipped with a differential pressure gauge (M[1]) * (inclined manometer or equivalent) to measure velocity head to within ten percent of the minimum value as determined during the preliminary traverse;
13. All glassware (cyclone, filter holder and impingers) should be interconnected with glass fittings having ball joints.
