NO MORE BAD DOOR.

Under Direction of an Expert the
Azotine Works Will Be Re-
modelled.
Mr.. Weiselogen, the expert engineer
of the Merz Extractor company. arrived
in st. Paul yesterday to overhaul the
azotine factory and find out what causes
the stencil here, while the system is a
success elsewhere. He went at once to
the works and inspected them thorough
ly. He evidently knows what is needed.
and from every appearance something
will be done promptly to abate the nuiS-
ance. Mr.. WelselOgen says that nearly
all the apparatus will require changing,
but that he hopes to have the new ma
chinery in working order within week.
Mr.. WeiSelOgen was found by GLOBE
reporter at the Windsor hotel. He said:
II have not made complete inSpec-
ton of the apparatus, but l have
seen enough to be able to say very
decisively what is the matter. In this
system of diSpoSing of garbage, it is
first put into large cylinders which are
heated to about 230 deg. Fahrenheit, and
thoroughly agitated by radial arms ex-
tending from a revolving shaft through
the center of the cylinder. This drives
out of the garbage all the water, the
carbonaeeous gases and the hydro
gen sulphide. leaving behind the
fertiiizing material entirely odorleSs.
The next problem is to destroy the gases
arising from this process. These are
first passed through an iron condenser
in which streams of cold water are con-
watery yapor, and all other gases, eX-
cept the sulphuretted hydrogen and the
carbonaceous gases. These are not con-
densble, and can only be burned by APP
plying fire to them when they are
heated to temperature of nearly 400
Fahrenheit. At this temperature. how
ever. they burn freely and completely.
The defects in the system here are the
large size of the condenser into which
they: gases first pass and the lack of
facilities for heating the remaining
gases to the required temperature be-
fore admitting them to the furnace. The
condenser in use here is the Preston
condenser, and is simply a large cylin-
drical tank. The gases are. of
course, very hard to confne,
and from this tank they will
escape in spite of all that can be done.
The condenser which they intend
putting in consists of four columnar
cylinders twelve or fifteen feet high
and twelve or fifteen inches in diam
eter. The gases are passed through
each of these in succession and are con-
densed much more thoroughly and do
not escape so freely.
1.-The heating apparatus that will be
used consists of retOrtS completely sur
rounded by a hot fire, and the gases
pass for nine feet, at the least, through
red hot walls before they are admitted
to the furnace. As soon as they
enter the furnace at this tempera-
ture they are entirely consumed and
none of them pass up the chimney.
Scribner, Libby 4 Co. are now figuring
on the condenser, and will announce
their rates in the morning. If at all
reasonable the work will commence at
once and continue night and day. tel
egraDhed this afternoon to Indianapolis
for models of the retorts. They will ar
rive Monday. BY next Saturday Hope
we can bave everything in place and
working. The proposed changes will
cost about 5000. This system is being
used successfully in Paterson, N. j.,
New Haven, Conn.,, Denver and Buffalo.
In all these places the factories are in
as densely populated sections as they
are here, and no complaint is made.
There is no reason why it should not be
a success here also. These plants are
now in construction in many other
places besides these, and will be work
ing sOon."
