Säätötuli combustion technology: perfect control of burning airs

Säätötuli biomass combustion technology for solid fuels

The Säätötuli biomass burner, built on our efficient combustion technology, is a high quality stoker-type burner for solid biomass fuels.

The Säätötuli burning technology ensures a high energy output and low emissions for a wide range of solid fuels. Based on huge thermal inertia, a wide combustion grate, a big firebox and a perfect control of combustion airs, the Säätötuli biomass burner is able to burn a large variety of solid fuels and maintain an exceptionnally low level of atmospheric emissions.

The grate is made of cast iron. Beginning from 80kW (273,000 BTU/hr) and above, all burners are equipped with a grate mechanism to push the fuel down the grate in an even way and reduce clinker. This allows the use of fuels with high ash contains.

From 150kW (512,000 BTU/hr) and above, the burner is equipped with a removable top and easily changable ceramics. This sturdy conception leads to a long lifetime and reduced maintenance costs. Most of the burners can be fitted with automatic ignition.

Different solid fuels: woodchips, peat, woodpellets

With Säätötuli’s efficient combustion technology, the nominal output of all burners is guaranteed for wood-based fuels up to 35% of moisture

In addition to that, Säätötuli burners are able to burn a wide range of solid fuels up to 50% of moisture. Here are some examples of fuels used in Säätötuli burners around the world:

  • wood-energy chips (biomass fuel produced with a chipper)
  • wood chips
  • pellets
  • peat
  • wood-industry leftovers
  • Corn cobs
  • fruit cores, nut shells…

We are always pleased to answer any questions regarding different fuels, don’t hesitate to send us your questions.

Please note that even if our burners are technically able to burn all types of biomass with a limited amount of atmospheric emissions, the use of some solid fuels may require environmental permitting depending on your province or territory.

All our systems can be fitted with additional flue gas cleaning systems.


Wood-energy chips VS. woodchips ?

Wood for wood-energy chips: hog, branches, treetops

The word woodchip is commonly used for the pulp and paper woodchips that are made with only the best parts of the wood and screened to have a constant particle size. Säätötuli’s biomass boilers do not need such a high-quality woodchip and it makes no sense to start competing with the pulp & paper industry for the same supply. Wood-energy chips are the best possible fuel to feed your boiler. Wood-energy chips are woodchips made from hog, branches, treetops, sawmill leftovers, etc. When made with a good chipper, no screening process is necessary as it would eliminate a part of the biomass.
