Furnace with radiant reflectors

摘要

The present invention utilizes radiation reflectors on the refractory wall of a fired furnace opposite the spaces between adjacent tubes. The radiation reflectors focus the reflected radiation from the flame onto the dark side of the tubes. The invention increases the overall heat transfer of the tube by increasing the heat flux rate for the backside of the tube, and also decreases the flux and temperature differentials between the front and rear sides of the tubes.
