since no hull changes would be permit
led. IN the British navy the Belleyllle
Water-tuhe boiler has been adopted for
an vessels larger than torpedo craft.
according, to the Statements of leading
british officials. the charges brought
against the Belleville boiler have mar
r"Wed down to a low efficiency in fuel
The official reports of the,
engineering departments do not. how
ever. bear out the Indictment. The big
.trllored cruiser Terrible, on her tria!
4
pounds of coal for each horse powa-
eNefted for an hour. On the trial trim
OF the British cruiser Diadem which
5rlal lasted for thirty hours. the coal
consumption per Indicated horse power
per hour was 1.59 pounds. This con
vas the equivalent of l3.a
pounds Of coal per hour per square foot
81 crate surface. On eight hours full
power trial of the Diaden1. when 5,a
;pai burnt was increased TO POS pounds
,ef hour per square foot of crate sur
ttce. ne coai was only increased to I6
"unuS per indicated horse power per
'ouf. steam was maintained at the on
slnes during the thirty hours and eight
hours runs. respectively, at 245 and o4e
pounds per square inch. The announce
nent of the official adoption of water
lllDe boilers for vessels of the United
states Navy is regarded in engineering
circles as a most important one
Briefly summarized the resulting advan-
ages are lishtness, ability to raise
steam quickly and accessibility for re-
pains No trouble is experienced in
raising steam to $50 pounds pressure
from cold water in much less than an
hours time. instances being recorded OF
tWcntE-three minutes only being con-
suned. II the case of the cylindrical
boiler from six to twelve hours are re-
Iuired. The danger formerly appre-
hendcd of tubular boilers breaking
down is no longer seriously entertained.
Tube boilers like cylindrical boiler;
must be cared for. and good Judgment
must be shown in handling them If
this is done there is no reason, in the
opinion, OF naval engineers, Why they
should not always respond when called
on for hard service.-Leutenant God
