Deterioration of Materials in a Quarter-Megawatt Strawburner

Abstract

An outline is given of the deterioration of refractories and stainless steels during the operation of a large strawburning furnace. The deterioration was caused by high temperatures, which sometimes exceeded 1400°C, and by a corrosive slagged ash. The use of different materials in alleviating these problems is described. Laboratory experiments on the corrosion of metals by straw slag are discussed, including work to determine the influence of chloride on the extent of corrosion.
