Certain Improvements in the Setting of Gas Retorts.
We, WILLIAM PIKE GIBBONS, of Ruiton House, near Dudley, in the County
Stafford, Manufacturer, and RICHARD MASTERS, of 7, Priory Street, Bedford,
in the County of Bedford, Retort Setter, 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 :-
Our invention relates to improvements in the setting of gas retorts.
In the type
of setting known as "producer". or "generator" setting provision must be made for
the admission of a secondary air supply to complete the combustion of the carbonic
oxide produced in the generator and it is of great importance that the air shall
attain such a degree of heat before meeting with the gases formed in the producer
that proper combustion may take place.
These requirements we obtain in a simple and effective manner by providing as
herein described small longitudinal air flues in the arch of the producer arranged
to admit and heat the air and cause it to properly combine with the said gases as
they issue through the producer nostrils.
We will describe our invention by referring to the accompanying drawings on
which Fig. 1 is a front sectional elevation of a bed of gas retorts with the producer
arch constructed according to this invention; Fig. 2 is a longitudinal sectional
elevation of the same taken on line X X of Fig. 1; Fig. 3 illustrates a slightly
modified method of carrying out our invention and Fig. 4 illustrates a further
modification of the same.
The same letters and numerals refer to corresponding parts in each illustration.
In carrying out this invention we construct the arch of the gas producer A first
of an inner ring or rings B formed of fire bricks throughout except where nostrils
or outlets C are required. In the drawings these nostrils are shewn in the centre
of the arch but they can of course be constructed on the right and left hand side of
the same if required. Over this arch B we construct an arch formed by preference
of specially moulded fire-clay blocks D (see Fig. 1) shaped as shewn so as to form
the said longitudinal secondary air flues in each side of the arch. These secondary
air flues are as shewn in Fig. 2 arranged in a zig-zag manner so that the air first
enters the two bottom flues E E' at their front ends which are open to the front
of the setting; the air then passes along these flues EE to the back of the
producer A and then returns to the front along the next flues FF1 and flows
back again along the next higher flues G G and returns again along the next
higher flues H H' and then flows again towards the back along the highest flues I I
and from these flues the air, heated as required, rises up through the hot air outlets J
opening immediately above the nostrils C, these hot air outlets J being arranged
as shewn so that the heated air will leave the flues I I¹ at such an angle as will be
best for combining with the carbonic oxide gases leaving the producer through the
nostrils C.
We find four secondary air flues in each side of the producer arch as above
described and shewn in our drawings to answer well in practice but it is to be
understood that the number of these secondary air flues in the arch may be
increased or diminished without departing from the nature of our invention.
Nor do we confine ourselves to any particular form of the fire-clay blocks or
bricks for forming the said arch and its secondary air flues as for instance instead
of each of the blocks D forming one of the flues being of the channel section shewn
by Fig. 1 each of these blocks may be made in halves D'D' as shewn in Fig. 3
and there may when required be an outer fire brick ring K over these special
blocks or as shewn in the further modification (Fig. 4) the said secondary air

page_text: flues may be formed by constructing the arch of the fire bricks L and outer
tiles M.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
€6
"
1. In gas retort settings of the type known as "producer" or generator'
settings the employment of secondary air flues in the arch of the producer or
generator the said air flues being arranged substantially as herein before set forth
so as to admit and heat the secondary air and conduct it to the producer nostrils
to combine with the gases issuing therefrom.
2. In gas retort settings of the type herein referred to provided with secondary
air flues in the arch of the producer or generator as denoted under Claim 1, the
various methods of forming the said secondary air flues in the said arch substan-
tially as herein before described and illustrated by the accompanying drawings.
Dated this 16th day of January 1893.
