Abstract
This paper attempts to show, directly and by implication, that serious dust and fume nuisances are still problems which, in specific cases of steel-making and steel-melting, await a really satisfactory solution which is also an economic proposition. Particular attention is drawn to the increased nuisance caused by oxygen enrichment.
In such cases it suggests that the basic design of the buildings is a stumbling-block not easily overcome. An original building lay-out is given. It illustrates how some firms have tackled the problems involved and suggests where there is scope for further investigation and research in furnace design and fume and dust analysis.
By way of contrast it states that many small dust nuisances for which the cures are fairly well known are not dealt with efficiently. The broad scientific approach to this problem is outlined.
Finally, it calls attention to the dispersion aspect of pollutants, which is becoming of increasing importance, and suggests that recent scientific investigations, carried out primarily for marine application, may be adaptable to land practice.
