Abstract
In the carbonyl process for the production of iron powder the carbonyl vapour is fed into a decomposition chamber at a rate greater than that which produces particles of a size partly 5m and partly greater, and a correspondingly greater amount of heat is supplied to decompose the increased throughput of carbonyl. The additional heat required is obtained by reducing the thickness of the chamber walls, or by using materials of high heat conductivity and not by increasing the temperature. The carbonyl may be diluted with carbon monoxide and ammonia may also be present. A throughput of 120 kgs. per hour at a temperature of 270 DEG C in a chamber 5 metres long by 1 metre diameter produces a powder 75 per cent of which is up to 3m and 25 per cent between 3m and 4m . The temperature should not exceed 300 DEG C in the decomposition chamber under ordinary pressure.
