IMPROVEMENTS IN REHEATING AND. MELTING FURNACES
Year: 1884

page_text: PROVISIONAL SPECIFICATION..
We FREDERICK-MONKS of Brooklands and THOMAS HALL of the Hollies, Iron
Manufacturers and THOMAS BURTON of Lovely Lane, Manager, all of Warrington
in the county of Lancaster, and WILLIAM BURTON of Withington Road, Aspul,
near Wigan, in the county of Lancaster, Manager do hereby declare the nature of
our said invention for IMPROVEMENTS IN REHEATING AND. MELTING FURNACES to
be as follows
The invention relates to furnaces with a deep fire place in which coal or like fuel
is burned so as to produce a mixture mainly of carbonic oxide and nitrogen which
mixture passes over a bridge and is burned in a chamber where the reheating or
melting takes place.
The object is to ensure more thorough and complete combustion of the products
evolved from the burning fuel. For the above purposes we construct furnaces with
horizontal passages in the roof or crown and also across the end and along the sides
of the furnace to the bridge we make openings from the said passages into the
furnace at and over the bridge and we blow air and steam through the said passages
and openings into the furnace by means of suitable blowing or forcing apparatus.
The passages in the roof or crown are preferably made by the use of perforated
bricks in building the furnace.
By constructing furnaces as above set forth the inflammable products of com-
bustion from the fire place are met above and below as they enter the reheating or
melting chamber where combustion takes place by jets of heated air mixed with
steam. The air steam and products are thereby thoroughly mixed the steain
becomes decomposed and combustion takes place at the required place in the most
advantageous manner.

"
The invention relates to furnaces with a deep fire place in which coal or like fuel
is burned so as to produce a mixture mainly of carbonic oxide and nitrogen which
mixture passes over a bridge and is burned in a chamber where the reheating or

The object is to ensure more thorough and complete combustion of the products

with horizontal passages in the roof or crown and also across the end and along the

the furnace at and over the bridge and we blow air and steam through the said
passages and openings into the furnace by means of suitable blowing or forcing

DESCRIPTION OF THE DRAWINGS.
Fig 1 is a longitudinal section, fig 2 a transverse section and fig 3 a horizontal
section of a reheating and melting furnace, a furnace walls, b fire grate, c fuel
chamber, d crown, e bridge, fhearth. h passages in the crown leading from the front
to the back and opening into the furnace at i over the bridge. The passages / all
open into the cross way; in front and the said way is connected by passages k
along the sides of the furnace with the way Z in the bridge. m openings from
through the bridge. n steam jet for blowing air and steam into ; and through the
ways and passages hk land out of the openings m and i at and over the bridge
where they mix. with the products of combustion from the fuel chamber. The
passages h are preferably formed by using perforated bricks in building the crown
of the furnace. Instead of a steam jet other suitable blowing apparatus may be
used and the air and steam may be forced into the passages and ways at the side
say near the bridge instead of in front. In this case only one sido passage k is
required and a separate passage for the blowing apparatus n below or at the
side of and opening into k and as shown by the dotted lines may be used
advantageously.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is
Heating and melting furnaces with passages ways and openings disposed
substantially as herein setforth through which steam and air is blown or forced..
