MUFFLE FURNACE FOR TEMPERING 175
These computations have once more confirmed the theory of
#aces developed by Professor Groume-Grjimailo, based upon
Jraulic laws.
Jn the author's opinion the computation for a furnace has
.0me a problem so simple and clear, that, when a furnace has
Yi correctly computed it cannot fail to work properly] it has
-0me possible to guarantee the correct working of a furnace
Jaout any more risk than is involved in the guarantee of the
formance of a turbine or a steam engine. It only remains to
,#in the best types of furnaces for each particular purpose, and
3 is impossible without the cooperation of the works and those
o direct them.
