Abstract
Flue gas entry into the tunnel(s) of a furnace is controlled by varying the flow conductivity or size of the individual or groups of openings through the entry ports. The openings can be provided either as gaps between adjacent blocks, or through bores of varying diameter, or as inserts having orifices of varying diameter and a profile matching the ports in which they are placed. Matching the flow conductivity (or cross-sectional flow area) and pressure drop through the individual ports to the desired mass flow, the flue gas flow can be distributed evenly, or as otherwise desired, into different ports, intervals, and/or regions of the tunnel.
