摘要

The gas distributor is divided into two chambers with separate gas attachments with gas nozzles positioned in a row, divided into at least two groups, and pointing at right angles from the gas distributor to the Venturi tubes from the burner bars. The gas distributor has a continuous, lengthwise partition as an extension of the axis of the gas nozzles. The first and second chamber (2,2') for the main gas flow has, in front of them, a first and second chamber (6,6')for the subsidiary gas flow towards the gas nozzles (3), Each chamber for the subsidiary gas flow is level with the gas nozzles branching off from the chambers and each has at least one gas nozzle (7) pointed towards the Venturi nozzles of the burners bars.
