<p>A gaseous flow reversing system is disclosed for use with a regenerative furnace. The reversing system includes a combustion air inlet unit (12) for receiving combustion air, and a valve unit (12). The valve unit is slidable between first and second positions with respect to the combustion air inlet unit for alternately directing the flow of combustion air from between the combustion air inlet unit (12) and a first regenerator port (26) when the valve unit is in the first position, and from between the combustion air inlet unit (12) and a second regenerator port (28) when the valve unit is in the second position. The valve unit (14) includes valve flow distribution channels (34a,34b,34c,34d) for distributing the flow of the combustion air into at least one of the regenerator ports from among a plurality of locations extending along the valve unit.</p> |
