Addendum to Titcomb report 8 February 1918

Addendum to Report on

GERMAN IRON INDUSTRY AND THE WAR.

By Harold Abbot Titcomb.

 

The question has arisen as to the actual size of the objective should German Blast-Furnace Works be attacked by aircraft with very heavy bombs. The following figures are reliable and conservative for an average of all the Iron Works in western Germany (excluding the small and scattered works in Siegerland.)

 

 

(1)   DANGEROUS AREA near the furnaces,—- 260 yards square = 14 acres. (closely)

(2)   FATAL AREA fatal to whole works,———-260 feet square = 1 ½ acres.

 

Thus one-ninth of the dangerous area is covered with vital machinery.

 

In the Table, two areas have been calculated, viz.,

(1), DANGEROUS AREA, which includes the blast-furnaces, hot-blast stoves, and the plant closely connected with them and surrounding them.

(2), FATAL AREA, within the Dangerous Area, being the actual ground-space occupied by the Blowing Engines, Power-plant, Pumps and Gas-washers.

 

Thus the “Fatal Area” as calculated and shown in the Table, does not include a large amount of damageable machinery necessary to the operation of portions of the Iron Works, such as Blast-furnaces, Hot-blast stoves, Cold-blast air piping, the huge and complex Hot-gas pipe system, Charging devices, Cranes, Rolling-stock & tracking, Electric wire cables for power and light, Water cooling pipe system, Machine and repair shops, Laboratories, Casting-houses Etc.,  most or all of which lie within the “Dangerous Area” .

Any iron metallurgist or owner of an Iron Works will acknowledge, therefore, that the Fatal Area as shown in the Table is indeed very fatal.

 

———————————-

 

In the Table following, the average of 7 German Iron works show actual areas of

(1) Dangerous Area, —285M. Sq. = 311 yards sq., =20 acres

(2) Fatal Area ————95     do   =104         do     =2¼   do

These 7 Works, however, are somewhat larger than the average iron works in western Germany; hence, after some consideration, I have given the above figures of 14 acres and 1½ acres, and regard these as conservative.
