Thermal Behavior of Floor Tubes in a Kraft Recovery Boiler - UNT Digital Library

12/9/1999 · The temperatures of floor tubes in a slope-floored black liquor recovery boiler were measured using an array of thermocouples located on the tube crowns. It was found that sudden, short duration temperature increases occurred with a frequency that increased with distance from the spout wall. To determine if the temperature pulses were associated with material falling from the convective
