5. Operation and service
Graphic illustration of the effect of the air volume selection is presented on the below drawing:
Too small air volume
Optimal air volume
Excessive air volume
Drawing 9 - Selection of air volume in Galaxia KWE boiler burner
If the volume of supplied air is too large in respect to the amount of the fuel fed it may be the cause of:
- lowering of cinders level below the combustion box pan edge,
- formation of slag,
- heating up and burning out of the scrapper claw,
- faster deflector wear,
- larger fuel consumption,
- putting the boiler out.
If the volume of supplied air is too small in respect to the amount of the fuel fed it may be the cause of:
- formation of a pile of unburned fuel on the combustion box pan,
- formation and sedimentation of soot in boiler exchanger,
- falling of unburned fuel on the ash tray,
- larger fuel consumption.
5.3. Resupplying of fuel
The fuel bin should be resupplied always when the fuel layer in the bin reaches the height less than 20 cm from the bottom. Supplied fuel should be dry. At
the moment of lifting the bin damper the bin opening sensor is initiated switching off the blower and feeder.
The fuel bin should always be closed tightly! Seal adhesion should be checked!
5.4. Stopping boiler operation
For the summer break it is recommended to:
- clean and protect the boiler exchanger (combustion chamber, water tube ducts, combustion tubes)
- clean the flue and chimney duct
- clean the retort combustion box
- clean the burner air chamber (unscrew M8 thumb nut and take of the burner air chamber cover)
- clean the bend of possible slag
- open the ash tray door
- remove fuel from the bin and protect the bin
- disassemble and remove the screw from the tube, clean and protect it
- cover with grease and mount in the feeder the screw shaft in the place of co-working with the gear motor
