COAL CONSUMPTION
- group I
Application
COAL CONSUMPTION function helps the user to monitor coal level in the coal hopper. Current coal
consumption is calculated based on volume of the hopper and efficiency of the stoker. Information about
current coal level in the hopper is provided as well. Alerts of the controller and of the room panel inform the
user that coal needs to be refilled. Additionally the user can monitor average coal consumption over time.
LIST OF PARAMETERS

:
(YES,

(YES,

I
1 Current estimated amount of coal in the hopper (0 - 100%, default setting 100%)
I
2 Actual stoker efficiency required to estimate coal consumption (1.0-20.0 g/sec, default setting: 6.5 g/sec)
I
3 Coal hopper volume (5-300 kg, default setting: 120 kg)
I
4 Low coal level alert (1 - 50%, default setting 10%)

CAUTION:
It is advisable to verify the estimation of coal consumption performed by the controller from time to time - parameter
I
1. If it is
evidently different from real consumption, it can be corrected.
If real coal consumption is lower than calculated by the controller, decrease parameter
I
2 (stoker efficiency)
.
If is higher than
calculated, increase the value of
I
2.
In order that coal level be calculated correctly, fill the hopper completely with coal and then correct the parameter
I
3 - Coal
hopper volume (default setting: 120 kg)
When coal level calculated by the controller drops below the value of the parameter
I
4 (default setting 10%) a red diode will
start flashing and the following icon will be displayed on the control screen (arrow flashing):
While adding coal into the hopper press [MODE] and then press [STOP] on the
[WORKING MODE] screen.
On pressing [STOP] a question will be displayed: "Have you refilled coal?"
If [YES] is selected, provide on the following screen how much coal was added and
confirm by pressing [SAVE]
or press [MAX] if the hopper was filled completely.
The controller will update coal level in the hopper (par
ameter
I
1).
