LINING FOR USE IN BLAST FURNACES

摘要

A lining for use in a blast furnace preferably for use in furnaces burning b io fuels, e.g. straw or wood chips or wood shavings and the like as well as ove ns in power stations where fuel having a biological origin is used includes an interior surface which is in contact with slag particles. The interior surfa ce is clad by elements (3, 4, 12) made by a ceramic or semi-ceramic material an d an insulation of a cement based foam material is arranged in one or more layers (17). The foam material is advantageously placed between the interior surface and an exterior load carrying construction which for example can be a steel pillar arranged exterior of the blast furnace. With a lining for blast furnace as describes above the risk of a collapse in the insulating material is avoided at the same time it is avoided that the interior wall deteriorate s due to the chemical composition of the slag particles which are present in t he bio fuelled oven.
