Inlet arrangement for collection of carry over for a vertical regenerator of an end-port furnace

Inlet arrangement for collection of carry over (10) for a vertical regenerator (80) of an end-port furnace (90) comprising:

• an inlet wall (20) comprising an opening for a port (21, 21″) for gas exchange towards an end-port furnace (90);
• a target wall (60) being arranged such that most of the hot gas incoming via the inlet wall (20) is initially deflected at the target wall (60);
• a barrier wall (70) comprising a recess (71) for gas exchange towards a pass (82) of the regenerator (80);
• a delimiting wall or delimiting walls (30, 40, 50), such as a floor (30) and/or a roof (40) and/or a sidewall (50);
• the inlet wall (20), the target wall (60), the barrier wall (70) and the delimiting wall or walls (30, 40, 50) define the inlet arrangement for collection of carry over (10) such that a gas flow entering the inlet arrangement for collection of carry over (10) via the opening for a port (21, 21″) will exit the inlet arrangement for collection of carry over (10) via the recess (71) or vice versa;
• characterized in that,
• the ratio between the area of the barrier wall (70) and the total area in the plane (73) of the barrier wall (70), limited by the delimiting wall or walls (30, 40, 50), such as the floor (30), the roof (40), the inlet wall (20) and the target wall (60), is in the range of 20% to 40%.
