Complete Specification Left, 17th Oct., 1894-Accepted, 17th Nov., 1894
We, FRANCESCO KOSSUTH, and LUIGI TEODORO KOSSUTH, of Naples in the
Kingdom of Italy, Engineers, do hereby declare the nature of this invention to
be as follows:-
This invention relates to means of introducing heated air into the fire boxes of
boilers so as to effect more complete combustion and prevent evolution of smoke.
The constructions which we adopt for this purpose have to be variously modified
to suit various types of boilers.
The accompanying drawings illustrate, by way of examples, the application of
our invention to several forms of boilers.
Fig. 1 is a longitudinal section, Fig. 2 is a transverse section and Fig. 3 is a back
view of the fire box part of a locomotive boiler.
We build in the fire box a sloping arch A of refractory bricks or blocks having
perforations a, these bricks or blocks being of various forms such as are illustrated
in Figs. 6 and 7.
These perforations communicate with the outer air by passages b which cross the
water way and can be more or less closed by a valve c worked by handle d. Air
entering at 6 becomes highly heated in passing through the arch, and meeting the
combustion gases as it issues from the perforations a effects their complete
combustion.
When the fire box is extended backwards to form a combustion chamber as
shewn in the part longitudinal section Fig. 4 and in the transverse section on XY
shewn in Fig. 5, we build a bridge B in the combustion chamber this bridge having
perforations a at the top or back or in both places, communicating with the open
air by passages which can be regulated by valves c. For boilers of marine type,
we build the arch A in the combustion chamber as shewn in Fig. 8 or in Fig. 9 or
we build a bridge as in Fig. 10 or a pyramid or cone as in Figs. 11 and 12,
providing in each case the perforations a passages b and valves c. In like manner
boilers of other types can be provided with perforated refractory arches or
structures, in their fire boxes, combustion chambers or flues, to operate in the
manner and for the purpose set forth.

Improvements in Steam Boilers.
We, FRANCESCO KOSSUTH, and LUIGI TEODORO KOSSUTH, of Naples, in the
Kingdom of Italy, Engineers, 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 means of introducing heated air into the fire boxes of
boilers so as to effect more complete combustion and prevent evolution of smoke.
The constructions which we adopt for this purpose have to be vario:13ly modified
to suit various types of boilers.

page_text: The drawings accompanying our Provisional Specification illustrate, by way of
examples, the application of our invention to several forms of boilers.
Fig. 1 is a longitudinal section, Fig. 2 is a transverse section and Fig. 3 is a back
view of the fire box part of a locomotive boiler.
We build in the fire.box a sloping arch 'A of refractory bricks or blocks having
perforations a, these bricks or blocks, being of various forms such as are illustrated
in Figs. 6 and 7.
These perforations communicate with the outer air by-passages 6 which cross the
water way and can be more or less closed by a valve c worked by handle d. Air
entering at b becomes highly heated in passing through the arch, and, meeting the
combustion gases as it issues from the perforations a, effects their complete
combustion.
.
When the fire box is extended backwards to form a combustion chamber as
shewn in the part longitudinal section Fig. 4 and in the transverse section on XY
shewn in Fig. 5, we build a bridge B in the combustion chamber this bridge having
perforations a at the top or back or in both places, communicating with the open
air by passages which can be regulated by valves c. For boilers of marine type,
we build the arch A in the combustion chamber as shewn in Fig. 8 or in Fig. 9 or
we build a bridge as in Fig. 10 or a pyramid or cone as in Figs. 11 and 12,
providing in each case the perforations a passages 6 and valves c.
In like manner
boilers of other types can be provided with perforated refractory arches or
structures, in their fire boxes, combustion chambers or flues, to operate in the
manner and for the purpose set forth.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we.
claim is :-
In combination with the fire box of a steam boiler, an arch, bridge or block
formed of refractory material having through it perforations or passages com-
municating with external apertures furnished with valves, for the purpose of
directing streams of heated air upon the combustion gases, substantially as
described.
