PROCESS DESCRIPTION
2 to 4 burners at each port and the regenerator chambers are connected at the rear wall side of the superstructure. The combustion of fuel and preheated air from one regenerator chamber takes place - flames starting from the burner nozzles and extending almost over the length of the furnace making a U turn before the front wall. Due to longer residence time of combustion gases there are less structural heat losses compared to cross fired regenerative furnaces.
