2.0 Fuel.
The
KSM-Multistoker
is constructed to operate on wood pellets, as already mentioned above. At the
Danish Test Station For Small & Medium Bio fuel Boilers it was tested and approved of using wood
pellets with a water content of about 8%.
However, both our customers and we have made the experience that the use of grain will result in a very
fine economy.
2.1 Wood Pellets
Wood pellets are produced at an increasing number of places in this country, all types are equally
applicable. However, there may be a difference in the size offered by the various suppliers. For this
reason it is recommended, when changing fuel supplier, to check that the pellet size is correct and that the
proper air volume is added.
Always store the wood pellets in a dry place, otherwise they will crumble and leave quite a bit of sawdust.
2.2 Grain
Grain is very easy to store and, in addition, it burns well - but grain has the unfortunate quality that it
forms rather a lot of clinker during the combustion, and this clinker may cause some problems in the
combustion chamber. But if 1-2 % of calcium is added every time the fuel container is filled, this will
largely reduce the formation of clinker.
KSM would therefore suggest to remove the remaining clinker once every second week, or when needed.
The clinker volume will be different following the specific type of grain or corn applied, and may even
vary from one field to the other.
Wheat should be preferred as this type of grain will cause the smallest amount of ashes. The calorific
value is the same for the various types of grain.
2.3 Alternative Fuels.
The biomass fuel types combustible in your stoker plant are only limited by your imagination, among
them might be:
Wood pellets
Grain
Cocoa pellets
Peas
Olive stones
It should be noted that this plant was tested with wood pellets only at the Danish Technology Institute,
however KSM answers for grain as an excellent type of biomass fuel.
