THESIS
UTHE FEASIBILITY OF USING A STHAL TRAP AS A WATER LYTER.,
The problem:— There are many cases in ceneral stean
engineering practice where it is desirable to use steam pres-
sures “nich are vaviable or constant, and where it is cesirabdle
+o rreasire in some way the amount of steam usec; in some cases
an expensive meteor is employed, cither on the stean line or
in measuring the water of concensation in the return. In the
majority of these casos we mist resort to steam trap to prevent

he is furnis sning his neignbor. To take account of this steam
a meter of some kind must be placed in tre line, and a stean
trap cmst be emloved to drain the piving system. roposed to us, is to use a steam tran

that aischnarres the collected water at intervals; that is,
the discharge is intermittent, the ranidity denenadins on the
pressure ana the amount of water of condensation. The Nason,

The above remults of our cxperinents, altnourch limited,
seer to incieate that the desired result ceannst be obtained
bpeeause the amount of water discharged per cium is not the
same for different pressures, ali we have no remilaur discharge
with oressures below 7-4. Tho failire to dietharge et low
oressures may be assirrned to friction in the varts, or to a
leaky valve in tre tran, but »recautions tere taken arainst

A vio. 11 Bundy Hydrox trap was experinented on nest. The
aduvaups of this tran were too rapid for us to take account of
them, therefore thre tran was useless for our purpose.
From the econsv~ruction of the Bundy High Pressure ctean
trap, we are lel to pelieve thet it could be used 4s a corm-
binet stean trad and water meter.
Wo were handicappec in tis work by not having at our
disposal a variety of stean trans to experiment with; if tre
had more trans vith us verhavs the results would be othervisc.
