tions, may be justified by the fact of tbe iion irdudiy in all time
having been of great interest to onr country, no less from an economica
point of view than from the consideration of the technical development
of our people.
Before proceeding to this, however, we must devote some atten
tion to the question which, as shown above, has excercised a deciding
influence on the development of our iron industry, namely the fuel
question.
Fuel.
The fuel used in our iron production is principally charcoal and
wood, while fossil coal and coke, as also peat and peat-coal, are less
in use.
Wood is used in the Swedish production of iron in heating
furnaces, often mixed with peat or coal, in the producers for Open hearth
furnaces, in puddling furnaces, and in the making of blister steel.
Charcoal. All pig iron and iron refined in forges is made exclusively
with charcoal. This charcoal is prodused principally in charring-stacks
in the forests, but also in charring-kilns at the iron works. There are
also along the coast in the northern part of the country a large number
of saw-mills where charcoal is made from the waste-wood, also by burning
in stacks. This so called saw-mill charcoal is transported in vessels and
by rail to the central part of Sweden, where the principal iron industry
is carried on.
