3 Commissioning
3.4 Switching on the boiler in the menu
Now switch the system “on” with the main menu item “System On / Off”. For suction conveyor units bear in mind
that the suction tank is not automatically filled during the block times. In this case filling must be executed in
accordance with point 5.2.3.10 of the operating manual with the function “Manual filling: Yes”. Ensure that a heat
request is present (e.g. activate boiler charging). Thereafter the system will start up as follows:
The fuel supply to the burner starts (“ Ignition filling”). If the fuel extractor is completely empty
(S, R) it can take up
to ½ hour for the conveyor line to fill to the level of the overfill switch of the stoker trough.
The boiler first pushes fuel ON to the burner plate (“Ignition feeding”) and then starts the ignition process (“Ignition
heating”). When commissioning the stoker worm is empty; this means that multiple ignition attempts are required.
This process can be shortened by switching the system off and on again after the “Ignition feeding” cycle to bypass
“ignition heating”.
After successful ignition the flue gas temperature increases – the fuel bed forms a ring. (“Complete ignition”).
The system then switches to “Nominal load”, heats up the boiler, and starts to supply consumers. When heat
consumption abates the boiler automatically cuts back its capacity and finally transitions to (“Ready (+req)”)
operating status when the target boiler temperature is reached.
Taking system measurements is an important step, however this step can only be
completely executed after an extended period of operation!
Reason: Residues of the boiler paint finish influence the emission values!
At least the CO
2
content of the flue gases should be measured during the commissioning process, in accordance
with section 6 “Measuring, pellet boiler”.
Schedule an appointment for a second commissioning process for optimal firing adjustment. The customer should
be offered the opportunity to sign a maintenance contract, in this regard.
Now instruct the system owner in how to operate the system; proceed as specified in the operating manual
for this.
