Parameter
Description
Duration for which the control dampers of the air channels (secondary air, primary air, cooling air) and the flue gas channels (furnace shut-off damper, furnace pressure control damper) remain open / in the purge position during purging.
The value adjusted here must be ≥ RECI: Delay time purge position.
The purge positions and the combustion air pressure are monitored during purging. A brief interruption (≤ 3 s) of the purging conditions (not a safety shut-off) results in a reset of the purge time.
When setting the purge time, ensure compliance with all the applicable standards and regulations for the firing plant!
