WinGD X92DF User Manual

Item Function Effect
010 PressCtrl mode 1 button Starts the PressCtrl mode 1
This mode is applicable only, if the steam pressure signal from
the steam plant is correct.
SPC compares the setpoint and the actual steam pressure. If
there is a difference, it opens or closes the EWG to change
the steam pressure.
If the status of the steam pressure signal changes to FAIL,
SPC will change to MinEWGPos mode.
011 PressCtrl mode 2 button Starts the PressCtrl mode 2
Same effect as PressCtrl mode 1: But, if the burner is ON, the
SPC uses the minimum permitted EWG position only.
012 Steam Pressure Setpoint Shows the actual setpoint of the steam pressure
You can manually set the setpoint, if the PressCtrl mode 1 or 2
is active.
It is only possible to set the setpoint if the specific LDU-20 is in
control.
013 Manual EWG Setpoint Shows the actual EWG setpoint
If the ManEWGSetp mode is active, you can enter the EWG
setpoint.
014 EWG Limitation Shows the current EWG setpoint together with the actual mini-
mum and maximum limitations
Too wide EWG opening decreases the scavenge air pressure.
This will start the auxiliary blowers.
The limit of the EWG opening prevents the scavenge air pres-
sure to decrease below the switching-On point of the auxiliary
blowers.
015 dIT Shows the delta injection timing (dIT)
SPC calculates the dIT. The dIT controls the timing of the fuel
injection. This timing is related to the difference between EWG
setpoint and the minimum permitted EWG position.
The ECS controls, if the dIT from SPC will be used or not.
Rule: If ICC is on, then dIT is not used.
4.16.3 Steam boost mode (SBM)
Steam boost mode is available as part of the steam production control system. The steam boost
mode creates more steam. Activating the steam boost mode avoids the continuous operation of
the main boiler. The steam boost mode is only available in the following power ranges:
•
51% to 91% of the contracted maximum continuous rating
•
76% to 91% of the engine power
Use the LDU-Screen to control the steam boost mode options.
