30 C.F.R. § 7.102 — Exhaust gas cooling efficiency test.
§ 7.102 Exhaust gas cooling efficiency test. (a) Test procedures. (1) Follow the procedures specified in § 7.101(a). (2) Install a temperature measuring device to measure the exhaust gas temperature at discharge from the exhaust conditioner. The temperature measuring device shall be accurate to ±4 °F (±2 °C). (3) Determine the exhaust gas temperature at discharge from the exhaust conditioner before the exhaust gas is diluted with air. (b) Acceptable performance. (1) The exhaust gas temperature at discharge from a wet exhaust conditioner before the exhaust gas is diluted with air shall not exceed 170 °F (76 °C). (2) The exhaust gas temperature at discharge from a dry exhaust conditioner before the gas is diluted with air shall not exceed 302 °F (150 °C).
