ARRANGEMENTS FOR THE ECONOMIC WORKING OF GAS PRODUCERS
Year: 1884

page_text: I DAN RYLANDS of Shepcote House, Stairfoot, Barnsley in the County of York
Glass Bottle Manufacturer do hereby declare the nature of my invention for
IMPROVED ARRANGEMENTS FOR THE ECONOMIC WORKING OF GAS PRODUCERS to
be as follows:-
Instead of passing steam direct from a boiler to the underside of the grates of
Gas Producers as is usually done I fix an exhaust & discharge fan or blower of
proper construction and drive this by a suitable engine. I fix suitable steam pipes
to convey the exhaust steam from this engine into the suction end or ends of the
fan or blower which suction end or ends is or are sufficiently large to also allow of
a quantity of air being drawn at same time into the fan-The exhaust steam and
air are by the revolution of the fan or blower forced along a blast pipe connected
to the discharge end of the fan or blower which blast pipe is connected to the
producers in a suitable inanner so that the mixed air and steam is forced into the
producers at any suitable points or places-By this arrangement the steam is first
used in driving the engine which works the fan and afterwards economised in
manner above described.
In connection with these improved arrangements I adapt iron doors for rendering
the undersides of the grates of the gas producers airtight so that the steam & air
cannot escape except through the producers Exhaust steam from other engines
may, where practicable and desirable be also piped or conveyed to the suction end
of the fan or blower.

page_text: I DAN RYLANDS, of Shepcote House, Stairfoot, Barnsley, in the County of York,
Glass Bottle Manufacturer, do hereby declare the nature of my Invention for
IMPROVED ARRANGEMENTS FOR THE ECONOMIC WORKING OF GAS PRODUCERS, and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
In order that my said invention may be fully understood and readily carried into
effect, I hereunto annex Drawings of which the following is a description :-
Figure 1 is an elevation showing an end view of a boiler, a side elevation of an
exhaust and discharge fan or blower, and-a-sectional elevation of a gas producer,
with steam and air pipe connections.
Figure 2 is a plan of an exhaust and discharge fan or blower showing the exhaust
steam pipes placed at the suction ends thereof.
Figure 3 is a front elevation of a gas producer showing the iron doors I adapt for
rendering the underside of the grates airtight.
Figure 4 is an end view of an exhaust and discharge fan or blower, showing
exhaust steam pipes placed at the suction ends thereof, which may convey exhaust
steam from other engines than the one illustrated in drawings annexed.
By referring to Fig. 1, it will be seen that instead of passing steam direct from
the boiler B to the underside of grates C of the gas producer D, as is usually done,
I fix an exhaust and discharge fan or blower E, which may be of the particular
make shown or may be of any other suitable design; I do not bind myself to any
special fan or blower. I drive this fan or blower E by the engine F, from the
counter shaft G; I fix suitable steam_pipes H H H to convey the exhaust steam
from the engine F to the suction end K or ends K K (Fig. 2) of the fan or blower E,
which suction end or ends (Fig 2) is or are sufficiently large to allow of a suitable
quantity of air being drawn through the spaces L L at the same time. The exhaust
steam and air which are simultaneously drawn into the suction end K or ends K K
(Fig 2) of the fan or blower E, are by the revolution of the fan or blower E forced
along the blast pipe M which is connected to the discharge end of the fan or
blower E, and the blast pipe M is connected to the underside of the grates C of the
producer D as shown, so that the mixed air and steam is forced into the producer at
any suitable points or places. By admitting the exhaust steam into the suction
end K or ends K K (Fig. 2) the heat which is retained in such steam is utilised in
heating the air which is drawn in at the same time, and the two elements by means
of the revolution of the fan or blower E are mixed together and forced along the
blast pipe M into the gas producer D, thus causing a thorough decomposition of the
coal and eliminating a greater amount of carbonic-oxide than where steam and air
are not forced into the producer in a mixed condition. It will be well understood
that by increasing the speed of the fan or blower E more blast would be forced out
of the discharge end O and necessarily more air drawn in through the spaces LL
of the suction end K, in which case more steam may be admitted, but such steam
must not be in excess of the quantity necessary for the proper combustion of the
coal in the producer; neither must the blast be in excess. It must be here under-
stood that although I only show on the drawings the fan or blower E operating
upon one gas producer D, it may nevertheless be so arranged as to operate on any
suitable number, and thus dispense with the necessity of having one fan or blower
to every producer. To carry out such an arrangement, it is only requisite to form
branches on the blast pipe M, and to connect pipes thereto from any other gas pro-
ducer. By means of my hereinbefore-described improved arrangements the live

page_text: steam from the boiler B is first used in driving the engine F (which engine F works
the fan or blower E) and afterwards economised in conveying to the blast its
retained heat, and after being mixed by the revolution of the fan or blower with a
requisite quantity of air is forced into the producer and thus economically disposed
of. In connection with these improved arrangements, I adapt iron doors P P
(Figs. 1 and 3), which are suspended on hinges, a a, and rest against the iron
frames, rr; a chain, 8, is attached to each door having a weight, u, at the end
thereof, which balances the door P, thus making easy the opening and closing of
the same. place a small iron door, g, between the iron doors P P, which may be
removed when required for the purpose of stoking. The iron doors P P rest tight
against the frames, 77, and thus render the underside of grates C of the producer D
airtight, so that the mixed steam and air cannot escape except through the pro-
ducer D. Exhaust steam from other engines than the one shown on the drawings,
may, where practicable and desirable, be also piped by means of the pipes HHHH,
and conveyed to the suction end or ends K. K of the fan or blower E, as shown at
Fig. 4.
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
1. The improved arrangements for the economical working of gas producers by
utilising by means of a fan or blower, the exhaust steam of the engine working
such fan or blower, or any other exhaust steam that may be available.
2. The special adaptation of iron doors in combination with the abovenamed
arrangement for forcing air and steam into the producers.
