I SAMUEL POPE of Tinsley House, Tinsley in the County of York, Steel Melter
do hereby declare the nature of my said Invention for "AN IMPROVED ARRANGE-
MENT OF INTRODUCING AIR INTO THE AIR REGENERATOR OF REGENERATIVE
FURNACES" to be as follows:-
The object of my invention is to introduce heated air into the air regenerator of
regenerative furnaces instead of cold air as usual, whereby the quality of the steel'
will be improved; and also to utilize the return heat from the hearth for the
purpose.
And my invention consists in causing the air which passes into the air
regenerator chambers on its way to the hearth to be heated by being first mado
to pass through a series of tubes or other similar arrangement affording extended'
heating surface inserted in the chimney fluc, such tubes or similar arrangement
being heated by the high temperature of the gases and other vaporous products
scaping from the hearth along the chimney-flue.
The course of the air is as follows: The cold air is drawn by the draught on the
furnace (or is forced by any suitable blast as may be required) into the heating
tubes, and after traversing the whole heating surface in the tubes passes from
thence into flues leading to the air regenerator chambers, and from these through
suitable ports into the open hearth or other furnace, where it mixes with the gases
in the usual manner.
The admission of air to the furnace is regulated as required by means of suitable
valves in the flues leading to the air regenerator chambers, such valves being
worked by means of rods and levers or other suitable mechanism so arranged that
when one valve is opened the other is closed, and they may also be arranged so as
to admit of their being worked independently of each other.
•
Such valves may likewise be worked either in connection with or independently
of the ordinary reversing valves. .

Regenerator of Regenerative Furnaces.
I SAMUEL POPE, of Tinsley House, Tinsley in the County of York, Steel Melter
do hereby declare the nature of my said invention for "AN IMPROVED ARRANGE-
MENT OF INTRODUCING AIR INTO THE AIR REGENERATOR OF REGENERATIVE
FURNACES "and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of my invention is to introduce heated air into the air regenerator of
regenerative furnaces instead of cold air as usual whereby the quality of the steel
will be improved and also to utilize the return heat from the hearth for the
purpose..
And my invention consists in causing the air which passes into the air
regenerator chambers on its way to the hearth to be heated by being first made
to pass through a series of tubes or other similar arrangement affording extended
heating surface inserted in the chimney flue, such tubes or similar arrangement
being heated by the high temperature of the gases and other vaporous products
escaping from the hearth along the chimney-flue.
The course of the air is as follows: The cold air is drawn by the draught on-the
furnace (or is forced by any suitable blast as may be required) into the heated
tubes, and after traversing the whole heating surface in the tubes passes from
thence into flues leading to the air regenerator chambers, and from these through
suitable ports into the open hearth or other furnace where it mixes with the gases
in the usual manner.
:
The admission of air to the furnace is regulated as required by means of suitable
valves in the flues leading to the air regenerator chambers, such valves being
worked by means of rods and levers or other suitable mechanism so arranged that
when one valve is opened the other is closed and they may also be arranged so as
to admit of their being worked independently of each other.
1
Such valves may likewise be worked either in connection with or independently
of the ordinary reversing valves.
By the above mentioned arrangement the air is caused to take up the heat that
would otherwise escape as waste heat, and this without admixture with the gases
and vapours carrying such waste heat, and the said air so admitted is thus heated
before it enters the air regenerator chambers merely by contact with the heated
surface of the series of tubes or other similar arrangement inserted in the chimney
flue as above stated.
In order that the invention may be fully understood I will describe it more
particularly by the aid of the accompanying drawings in which is represented an
arrangement such as is above referred to.

page_text: The cold air is caused to enter the heating arrangement F through the pipe G,
it then becomes heated and passes out of the heater F as hot air through the outlet
pipes H and valves I into the flues D, and then through the openings M into the air
regenerator chambers C, finally passing into the open hearth or other furnace A
through suitable air ports B, where it mixes with the gases in the usual manner.
The admission of the air to the furnace is regulated as required by suitable
valves I leading to the air regenerator chambers C being worked by handles J
(fig. 3) or screws together with a suitable rod and lever arrangement, so as either
to alternately open and close the valves I as shewn in fig. 3, or so that they may
work independently of each other.
The valves I may likewise be worked in connection with or independently of the
ordinary reversing valves K (figs, 1 and 2).
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
The arrangement for introducing heated air into the air regenerator of
regenerative furnaces instead of cold air, as is usual, by means of which arrange-
ment the return heat from the hearth is utilized but without admixture with the
gases and vapours carrying the said return heat, in the manner substantially as
herein before described.
