Here you will find the answers to some of the typical questions regarding the operation of a biomass plant. If you do not find the answer you need, you are always welcome to contact us.

  • Due to an inefficient combustion.
  • Oxygen percentage may be too low. This is indicated on the control panel and should be between 8-9%.
  • There may be too much fuel in the boiler. Check observation glass and/or open the cleaning hatch.

Oxygen percentage may be too high. This is indicated on the control panel and should be between 8-9%.

Straw boiler:

  • Stop plant, check for twine around shafts and/or bearings on shredder drums.
  • Check that the ampere level on shredder control panel is not too low.
  • Check for negative pressure in the combustion chamber. Check the small metal pipe and hoses (to the negative pressure gauge), placed at the front of the boiler where the fuel is inserted, for blockages. Clean with a cotton bud or similar if necessary. Also check the rubber flaps on the cell sluice.
  • Stop the plant and check if the rubber flaps are worn and need to be replaced.
  • Damper motor on the boiler flue must be fully open when starting the boiler. Check if it is open on the setting indicator.
  • . .

Can be due to negative pressure in combustion chamber (see FAQ “Smoke in the boiler room?”)

Check if the valve membranes are worn or damaged.

Check membranes around pressure valves for leaks.

Oxygen gauge should show 20.9% (atmospheric air) when plant is inactive. If it shows between 0% and 20.9% when inactive, the probe may be covered in soot. Remove and clean the probe.

  • Check sprinkler system for water and pressure. Fill sprinkler tank with water.
  • Reset/restart Danfoss Pressostat RT110.

Likely due to foreign objects in the ash such as stones. Stop the plant. Use automatic reverse function on ash worm drive if fitted. If not, contact an electrician to reverse the drive by reversing the current.

Panel has double clamps. Check at the back for a second row of clamps.

  • Change or sharpen the shredder blades if necessary.
  • Stop plant, check for twine around shafts and/or bearings on shredder drums.
