The biomass burner is designed in a way not requiring complicated
operation and expensive maintenance. However, its correct operation
(influencing boiler performance and burning economy) requires certain
rules to be observed during the feeder operation and regular perfor-
mance of certain activities.
1. A periodic inspection of the furnace in operation can only be per-
formed through the furnace door.
2. Remove regularly sintered and unremoved slag when present in
large quantities in the boiler furnace (it may block air supply).
3. Check the fuel level in the tank.
4. Fuel loaded into the tank must be dry.
5. Check whether no dust or other waste accumulated in the tank and
the feeder cover pipe, and remove it when necessary.
6. Check condition of air nozzles and patency of air outlets.
7. Periodically clean dust and residues of coal or ash from the feeder.
8. Regularly clean the motor casing using a dry cloth.
9. Do not use any solvents for cleaning as they may damage sealing
rings and gaskets.
10. When the boiler, together with the feeder, is removed from opera-
tion, quarterly start screws, the moving grate mechanism and the
blower fan for 15 minutes – thus preventing any blocking of the
moving components.
11. Check for accumulation of dust or other waste in the air chamber –
through a side clean out hatch (see Fig 6, Fig. 7).
12. Regularly monitor condition of screw connections in: fuel tank with
the fuel feeder, feeder with the boiler, and closing of the side clean
out hatch, and adjust the front door setting with hinges and adjust-
ment screws, whenever necessary.
