Reformer tubes emissivity
WebThe emissivity of the body generally becomes smaller as the incident angle is reduced. For an average reformer tube measured at a 90° incident angle, 85% of the radiant signal received by the pyrometer is emitted by the tube, and the other 15% has been reflected by the tube and originated from surrounding objects. WebUsing direct tube contact the gold cup creates a seal between the tube surface and the instrument, shielding the thermocouple from additional radiation around the tube Enables …
