Hydraulic bottom

Size class: 40 – 500 kW
Fuel: Mixed fuel, Peat, Peat pellet, Wood chips, Wood pellet
Guarantee: 1 year

  • Hydraulic bottom is ecquipped with scrapers that prevent fuel from making vaults in the fuel hopper.
  • Module structure of the feeding system makes possible to place it to the different spaces in lot of combinations.
  • Module hydraulic feeding system is the biggest model for tractor loading.
  • The size of one modul is 1 meter or 1,5 meter × 1,5 meter
  • Largest bottom made from moduls is 3 × 4,5 m
  • Hydraulic feeding bottom is designed for big fuel amounts, but it still has effective feeding and easy-to-use features.
  • Hydraulic feeding bottom is easy to install to existing spaces, it doesn’t need the floors to be in different level, which is very important when making concrete basement.
  • Thanks to it’s construction, service and repairs are easy to do without emptying the fuel hopper.
  • PLC C570E controls the operation of the unit.Hydropohja

Burner heads

Säätötuli burners and their grates are durable and longlife.

Thanks to construction Säätötuli bioburners make burning process clear and efficient: as a result there is high efficiency ratio and small amount of ashes.

All burners are air cooling and as fuel can be pellets, peat briquettes and wood chips used.

Säätötuli burners are tested in VTT (Technical Research Centre of Finland) and SP (technical Research institute of Sweden) to meet EN 303-5 standard requirements.

Correct use of the bio-burners and regular maintenance will ensure reliability and long life for the burner.

 

Säätötuli- burner 40-60 kW

  • Is made of steel
  • Burning air is fed by one air fan. Primary and secondary air is devided inside the burner with special construction.
  • 40 kW burner can also have a grate mechanism, which is very convinient to use with grain and peat as fuel.
  • Inner cast iron part can be easily taken off and changed.
  • Burner air feeds by 1 air fan. Air divides to primary and secondary air inside the burner thanks to its construction.

Säätötuli-burner head 80-120 kW

  • Is made of steel
  • Burner is equipped with 2 air fans: 2 different air feeding fans for primary and secondary air make possible to have optimum burning and small air coefficient, so the smoke gases burn clearly.
  • Thanks to 2 air fans burning air proportion can be changed and adjusted depending on the used fuel.
  • 80 kW burner is always equipped with grate mechanism (”moving grate”) to help burning cleanig from ashes.
  • Grate mechanism is especially important when using peat or grain (also grain drying waste) as fuel.
    Säätötuli burner head

150-500 kW

  • Burner head is ceramic, grate surface is cast iron
  • Burner is equipped with 2 to 4 fans.
  • Burner is equipped with 2 air fans: 2 different air feeding fans for primary and secondary air make possible to have optimum burning and small air coefficient, so the smoke gases burn clearly.
  • Thanks to 2 air fans burning air proportion can be changed and adjusted depending on the used fuel.
  • Over 200 kW burner head has removable roof and this makes the maintenance of the burner head more easier.
  • Ceramic stones of the burner head can be changed.

SAFETY SYSTEMS

Safety Pack
Safety system uses pressure sprinkler valves to ensure safety during electricity or waterlines failure.

Safety Pack Pulse
Safety system with magnetic valves.

Safety Pack Pellet
Safety system working with powder extinguishers: convinient to use with pellets, where water can damage feeding tubes and augers .

GSM ALRM SYSTEM

GSM modem sends SMS to the mobile in case of possible malfunctions of the burner of feeding.

In most of PLC control boards the GSM alarm system is built in the control box and programm.
