Improvements in Means for Supplying Purified Water to Steam
Boilers.
We, WILLIAM JAMES TRANTER, of Workhouse Lane, Tipton, Engineer, and
OLIVER HOWL, of Tipton Engineering Works, Tipton, Engineer, both in the
County of Stafford, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in means for supplying purified water
to steam boilers, so that the sedimentary matter may nearly all if not quite all
removed therefrom and we prevented from entering the boiler, and the water
injected into the boiler at a high degree of temperature.
The apparatus consists broadly as follows:-As applied to a Lancashire or
Cornish boiler, we provide that the cold water shall be pumped into a tubular coil
situated in the smoke box at the end of the flue or flues, or thereabouts. From
this coil the water is now carried along by a pipe or pipes along the flue and furnace
to the front of the boiler whence it is carried upwards into a chamber above the
boiler. Within this chamber the now heated water is thrown upon alternating
surfaces such as a series of plates, or conical surfaces so that the water shall be
thereby broken up as much as possible, in order to permit of the sediment being
arrested by these surfaces. . The water passes thence into the boiler by the force
of the pump, through an ordinary non-return valve. From this chamber is also
placed a blow off cock so that from time to time as may be desired the sediment
may be blown off.
The precise details of the apparatus may be varied in order to suit the various
shaped boilers to which it is intended to apply it.

page_text: County of Stafford, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:
This invention relates to improvements in means for supplying purified water
to steam boilers, so that the sedimentary matter may nearly all if not quite all
be removed therefrom and be prevented from entering the boiler, and the water
be injected into the boiler at a high degree of temperature.
The apparatus consists broadly as follows:-As applied to a Lancashire or
Cornish boiler, we provide that the cold water shall be pumped into a tubular coil
situated in the smoke box at the end of the flue or flues, or thereabouts. From
this coil the water is now carried along by a pipe or pipes along the flue and
furnace to the front of the boiler whence it is carried upwards into a chamber
above the boiler. Within this chamber the feed water is thrown upon alter-
nating surfaces such as a series of plates, or conical surfaces so that the water shall
be thereby broken up as much as possible, in order to permit of the sediment being
arrested by these surfaces. The water passes thence into the boiler by the force
of the pump, through an ordinary non-return valve. From this chamber is also
placed a blow off cock so that from time to time as may be desired the sediment
may be blown off.
In order to more clearly explain this our invention we have appended hereunto
an illustrative drawing upon which are figures and numbers of reference.
Fig. 1, is a general view in part section of the invention.
Fig. 2, shows modified forms of plates upon or by which the water is broken
up and distributed.
Fig. 3, is a sectional plan view on line A-B (Fig. 2).
The precise details both as to shape and arrangement may be varied in order to
suit the various shaped boilers to which it is desired to apply it.
As shown it is generally suitable for a Lancashire or Cornish boiler, in which 5,
is the feed water pipe from the feed pump (latter not shown). This feed water
is discharged through the rose 6, into the chamber 7, formed by the vessel 8.
This supply may be controlled by the tap 9. This vessel 8, has a removable
cover 10, to which is preferably attached the hood 11, so that as the water is
discharged it shall be thereby directed upon the plate 12. The shape of this hood
may be varied as desired. The plates 12, are suitably supported, which may be
readily done by means of the central pillar 13, carried from the base 14, which may
be fixed on the pipe 15, or be carried from vessel 8, itself. When used in con-
nection with the pipe 15, the upper part of the base 14, may have openings 16,
through which steam may be injected from the boiler through the pipe 15.
In some cases the shape of the plates 12, may be modified as for instance as
shown in Figs. 2, and 3, in which 12 shows plates conical in shape, which may be
further modified as seen at 12b which are also grooved radially; the object in each
case being to break up the particles of water as much as possible.
17, is the supply pipe to boiler, which also of course permits steam to pass
into the vessel 8. 18, is a blow off cock by which the sediment may be blown off
from time to time from the vessel 8.
Thus as the water is thoroughly broken up in the vessel 8, and mixed with the
steam the foreign particles of matter are separated and arrested and fall to the
bottom while the water is more readily raised to a high temperature for passage
into the boiler.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. The improved apparatus substantially as described and shown and for the
purposes specified.
2. The combination with the feed supply pipe 5, and placed between it and the

page_text: boiler, of the vessel 8, with plates 12, 12ª, 12b and communication pipe 15, with
or without blow off cock 18, and with or without pipe 15, all substantially as set
forth and shown.
Dated this 20th day of January 1898.
