IMPROVEMENTS IN REGENERATIVE PROAL
Year: 1881

page_text: LETTERS PATENT to Samuel Pope, of Newburn, in the County of Northum-
berland, Steel Melter, for an Invention of "IMPROVEMENTS IN REGENERATIVE
PROVISIONAL SPECIFICATION left by the said Samuel Pope at the Office
of the Commissioners of Patents on the 13th September 1881.
SAMUEL POPE, of Newburn, in the County of Northumberland, Steel Melter."
"IMPROVEMENTS IN REGENERATIVE FURNACES AND APPARATUS CONNECTED

THEREWITH."
My Invention relates to regenerative furnaces employed in the manufacture of
iron, steel, glass, and other materials, and consists in the adaptation and application
thereto of independent connecting flues between the draught flue leading to the
chimney (or any subsitute therefor) and the regenerative chambers for the purpose
of regulating the quantity of gases, smoke, and other products of combustion passing
through the said chambers. One or more independent flues is or are constructed
between the regenerative chambers or their outlets and the draught flue, and in
each of such flues are inserted regulating valves or dampers.
By this arrangement is obviated the inconvenience that has arisen from the
liability of the regenerative chambers as ordinarily constructed to fail in passing
through them their due share of the products of combustion, thereby causing a loss
of heat to the incoming air or gases, and an overheating of the brickwork forming
the ports, flues, tubes, and chequerwork. There is also obtained an increase of
durability in the material of which the furnace is composed; also a greater range
of power to regulate the temperature and processes inside the furnace; also a
means of greatly increasing the intensity of the heat when required; and also an
increase of economy in working.
The additional dampers may be applied with but little alteration to existing
furnaces, but with new furnaces it is preferred that the branch flue or flues
connecting with the chimney or draught flue the flue that connects the air
reversing valve with the regenerator for air should be placed in a straight line
through the regenerator for air, and the flue connecting the air reversing valve
with the regenerator for air and parallel with a centre line passing through the
gas reversing valve and the air reversing valve, thereby causing the distance of the
chimney or draught flue from the regenerators to be increased.

" IMPROVEMENTS IN REGENERATIVE FURNACES AND APPARATUS CONNECTED
THEREWITH."
My Invention of "Improvements in Regenerative Furnaces and Apparatus
Connected therewith " relates to regenerative furnaces employed in the manufacture
of iron, steel, copper or alloys, glass, bricks, pottery and other materials, and
consists in the adaptation and application thereto of independent connecting flues
between the draught Blue leading to the chimney (or any substitute therefor) and
the regenerative chambers, for the purpose of regulating the quantity of gases,
smoke, and other products of combustion passing through the said chambers. One
or more independent flues is or are constructed between the regenerative chambers
or their outlets and the draught flue, and in each of such flués are inserted
regulating valves or dampers.
By this arrangement is obviated the inconvenience that has arisen from the
liability of the regenerative chambers as ordinarily constructed to fail in passing
through them their due share of the products of combustion, thereby causing a
loss of heat to the incoming air or gases, and an overheating of the brickwork
forming the ports, flues, tubes, and chequer work. There is also obtained an
increase of durability in the material of which the furnace is composed; also a
greater range of power to regulat temperature and processes inside the furnace ;
also a means of greatly increasing the intensity of the heat when required; and
also an increase of economy in working, cooling, and starting.
The additional dampers may be applied with but little alteration to existing
furnaces, but in new furnaces it is preferred that the branch flue or flues connecting
with the chimney or draught flue the flue that connects the air-reversing valve
with the regenerator for air should be placed in a straight line through the
regenerator for air and the flue connecting the air reversing valve with the
regenerator for air, and parallel with a centre line passing through the gas-reversing
valve and the air-reversing valve, thereby causing the distance of the chimney or
draught flue from the regenerators to be increased.
Having thus stated the nature of the said Invention, I will proceed to describe
more particularly in what manner the same is to be performed by the aid of the
accompanying Drawings, in which are represented the improvements above
referred to.

page_text: with the chimney or draught flue B. The flues L, L, pass below the flues H, H, as
shewn by dotted lines in Fig. 2; M and M' are circular valves or dampers inserted
in the flues L, L, having their seats at N and N'; O and O' are rods for regulating
the distances respectively between the valves M and M¹ and their seats N and N₁,
by lowering the valve from its seat or drawing it up close thereto as required.
These rods may be worked directly from the level of the floor, or indirectly by any
convenient means. Each time the valves C and D are reversed one of the
valves M or M' has to be closed and the other has to be opened.
It is to be observed that as the regulating damper E and the valves M and M'
are quite independent of one another, they can be opened either singly or together,
When the regulating damper E and either the valve M or M₁ are opened, the
draught through one of the air regenerators F is greatly increased. When it is
thought desirable, the air regenerators may be placed outside the gas regenerators,
by which all the flue arrangements will be considerably simplified.
The Drawing as above described illustrates one method of applying my Invention
with but little alteration to existing furnaces, but in a new furnace the flues L, L,
as shewn in Fig. 3 would be preferably formed and arranged in a line, being a
continuation of a straight line through the regenerator F and the flue K, and
parallel with a central line through the valves C and D, thereby causing the
distance of the chimney or draft flue B from the regenerators to be increased as
required.
Having thus described the nature of the said Invention and in what manner the
same is to be performed, I hereby declare that I do not claim as of my Invention
the arrangement of a pair of flues passing a reversing valve, as this has before
been used, but what I do claim as of my Invention is,-
The adaptation and application to regenerative furnaces of independent
connecting flues between the draught flue leading to the chimney (or any substitute
therefor) and the regenerative chambers (either in addition to the flues leading to
the reversing valves or in substitution for the same), as and for the purpose or
purposes hereinbefore described.
In witness whereof, I, the said Samuel Pope, have hereunto set my hand
and seal, the First day of March, in the year of our Lord One thousand
eight hundred and eighty two.
