11 Claims.
This invention relates to- boiler cleaners and
has particular reference to a boiler cleaner of the
type which includes means for discharging jets
of cleaning ?uid adjacent portions of the boiler
5 to be cleaned.
One of the primary objects of this invention is
to provide in a boiler cleaner of the above men
tioned character, means for prolonging the life
of the pipes and conduits which are provided for
10 supplying cleaning ?uid to the blower elements of
the boiler cleaner.
I
shaped members provide cleaning ?uid passages
20 with which discharge openings 2| communi~
cate, these openings being arranged so as to dis
charge cleaning ?uid in the desired directions
within the boiler.
By integrally uniting the blower element form
ing members 18 to the boiler tubes I9, it will be 10
understood that the! blower element forming
members will be maintained relatively 0001 even
during the periods when they are not being sup
conduits and the like will be maintained rela
plied with cooling ?uid. It is to be understood
however, that if desired, the blower elements 15
?uid is not passing through the same.
This application is a division of my cor-pending
application Serial Number 428,721 ?led February
15, 1930, which has now issued as Patent No.
1,992,336.
Numerous other objects and advantages of this
invention will become moreapparent as the fol
lowing description proceeds particularly when
reference is had to the accompanying drawings
25 wherein
Fig. 1 is a semi-diagrammatic elevational view
of a portion of a boiler showing my invention
applied to the same;
Fig. 2 is a fragmentary side elevational view
partly in section of the structure shown in Fig. 1;
Fig. 3 is a sectional view taken substantially
on the line 3--3 of Fig. 2;
Fig. 4 is a transverse sectional view through
a slightly modi?ed type of construction; and
Fig. 5 is a horizontal sectional view taken sub
stantially on the line 5-5 of Fig. 4.
, Referring then particularly to the drawings
wherein like reference characters designate cor
responding parts throughout all views, the nu
40 meral I0 designates generally a boiler having
upper and lower headers or drums II and I2 re
spectively. Connecting the boiler headers in
accordance with the usual practice, is a bank l5
of boiler tubes, the tubes being suitably arranged
in rows and the lowermost row or that row near
est the ?rebox being designated by the reference
character IS. The numeral I1 designates a por
tion of the boiler wall which encloses the boiler
drums and tubes.

, I
For cleaning portions of ?the boiler, blower?ele
ments are provided, these blower elements being
so arranged within the boiler as to discharge
cleaning ?uid adjacent portions thereof to be
cleaned. While these blower elements may be of
any desired character, they are diagrammatically
may be of any desired character, that is either
integrally secured to certain boiler tubes as illus
trated, or free from connection with the boiler
tubes, the present invention being directed more
particularly to the means for supplying cleaning 20
?uid to these blower elements or passages.
Referring now more particularly to Figs. 1
and 2, the numeral 25 designates a cleaning ?uid
supply header which, as illustrated, projects ex
teriorly of the boiler wall and is preferably pro 25
vided with a control valve 26.
This header ex
tends longitudinally of and lies close adjacent the
boiler drum or header 12 with the result that
this header is maintained relatively cool by
virtue of the cooling in?uence of the relatively 30
cool drum.
,
Connecting theheader 25 with the blower ele
ments [8 are branch pipes 21 and by reference to
Fig. 2Iof the drawings, it will be noted that these
branch?pips also lie close adjacent the drum I 2
so as? to be cooled by the latter; Additionally,
as ?illustrated in Fig. 3 of the drawings, these
branch? pipes 21 preferably lie close to the boiler
tubes of the bank 15, with the result that besides
being maintained cool by virtue of their proximity 40
to the boiler drum, they are also being main
tained cool by virtue of their proximity to the
relatively ?cool boiler tubes. The branch supply
pipes are shown as being slightly bent as at 28
whereby they may yield slightly to compensate 45
?for relative movement between the boiler tubes to
which the blower elements are secured and the
{header incident to differences in expansion and
contraction of the header and the boiler tubes.
Asthus far described, it will beapparent that
the invention provides blower elements suitably
located within a boiler for discharging cleaning
?uid adjacent portions of the boiler to be cleaned.
,While these blower elements may be of any de
sired character, they are preferably integrally

vapor space of the boiler and is thus wholly pro

by these boiler tubes.
The invention further provides a cleaning ?uid
tected from destruction by the boiler heat. Ad
ditionally, the branch supply pipes which con
nect the supply header to theblowerelements are
header which although it is disposed ?within the
either located wholly within?the vapor space of
boiler is positioned in proximity to andprefer
the boiler or partly in the vapor space, and in the
latter case are so arranged that even when they
are out of the vapor space of the boiler, they lie
ably above the boiler drum or header so that it
is not only kept cool by the relatively cool boiler?
drum but is also shielded by the latter from direct ? close adjacent relatively coo-l boiler parts and are 10

so arranged that they are also adequately 20
20 ments and the supply pipes and conduits there- -
for will be protected from destruction by the heat
of the furnace even during the intervals when
they are not supplied with relatively cool cleaning
?uid. Thus the invention provides a construction
25 which may be incorporated in a relatively hot part
of the boiler but which will nevertheless possess
a relatively prolonged life.

In Figs. 4 and 5, a slightly modi?ed type of
construction is disclosed in- which boiler tubes
35 and 36 are disclosed as communicating with a
boiler drum or header 31. Extending longitudi-i
nally of the boiler tubes 353are'blower elements
40 provided with suitable discharge nozzles M
for directing jets of cleaning fluid adjacent por
35 tions of the boiler to be cleaned.
Extending longitudinally of the boiler tubes 36
are blower elements 45, these elements being like
wise provided with suitable discharge nozzles 46.
As in the previously described form of construc
40 tion, the blower elements are preferably crescent
shaped members welded or otherwise formed sub
stantially integral with their? respective? boiler
tubes, whereby the blower elements are main
tained relatively cool.
]
In this modi?ed form ?of construction there is
45
disclosed a cleaning fluid supply header ?50 which
is disposed wholly within the boiler drum 31 ?and
which is therefore fully protected by ?the v?uid or
the vapor in this boiler drum. It .will be under
50 stood that at its ends the header'projects exte
riorly of the boiler wall and is preferably provided
with one or more valves for controlling?the flow ?of
cleaning fluid to and through the header.
Connecting the blower elements? 40 to the
55
header 50 are branch pipes 5|, these branch pipes
passing through the wall of the boiler drum 3'!
and communicating with the blower elements as
at 52.
It will be noted that even exteriorly ?of
the boiler drum these branch pipes lie close adja
cent the boiler drum and their respective boiler
tubes and further are shielded from the furnace
gases by their respective boiler tubes,

'
? For the sake'of convehiencafthe invention has
been described'as being embodied ?in'a cleaner
for cleaning boilers. ? It will be?apparent however, 25
that the inventive principles ?disclosed may be
embodied in a devicev 'for?j cleaning'k'apparatus
similar to boilers and? it? is to be therefore under
stood that wherever the word ?boilers? is utilized, 30
it is to be construed as meaning heatexchange
apparatus of any character whatever; while the 5
words ?boiler cleaner? are to?b'e ?construed? as
meaning a cleaner for any such type of apparatus.
While the invention ha's'l?bleen" [described with
some detail, it is to be understood-that the de 35
scription is for the purposes of illustration only ?
and is not de?nitive of the ?limits of the inventive
idea. The right is reserved'to'make such changes
in the details of constructionvand arrangement
?of parts as will fall within the purview of the 40
attached claims.
