1 LAURENCE HILL ARMOUR of 16 West Street, Gateshead-on-Tyne in the
County of Durham, Civil Engineer do hereby declare the nature of this invention
to be as follows:-
―:
My invention relates to ovens, furnaces or retorts used for the making of coke
or charcoal or for distilling or roasting carbonaceous matter or otherwise subjecting
carbonaceous matter to the action of heat so that gases are given off which usually
contain pitch or tarry matter or ammonia or both and my invention has for its
object to provide means whereby the clogging and obstruction of the outlet by
pitchy or tarry deposit is prevented and decomposition of ammonia is also prevented
or to a considerable extent prevented. With this object I supply water or other
liquid or aqueous vapour at a temperature lower than the effluent gases and in
regulated quantity at or near to the outlet for the gases escaping above the charge
in the oven furnace or retort by which the gases pass or are withdrawn so that the
gases as they pass thereto or thereinto are cooled and moistened and pitchy or heavy
tarry matter is prevented from accumulating in the outlet passages and it will also
have the effect of assisting in the condensation of aminonia and of preventing or in
a considerable degree preventing the decomposition thereof.

COMPLETE SPECIFICATION.
Improvements in or connected with Ovens, Furnaces, or Retorts
used for the Making of Coke or Charcoal, or for Distilling or
Roasting Carbonaceous Matter, or, otherwise subjecting Car-
bonaceous Matter to the Action of Heat.
LAURENCE HILL ARMOUR of 16 West Street, Gateshead-on-Tyne in the
County of Durham, Civil Engineer, 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 :-
My invention relates to ovens, furnaces or retorts, used for the making of coke,
or charcoal, or for distilling, or roasting, carbonaceous matter, or otherwise sub-
jecting carbonaceous matter to the action of heat, so that gases are given off and
escape above the charge which gases usually contain pitchy, or tarry matter, or
ammonia, or both such matter and ammonia; and my invention has for its object
to provide means whereby the clogging and obstruction of the outlet by pitchy,
or tarry deposit is prevented and decomposition of ammonia is also prevented, or
to a considerable extent prevented. With this object I supply water, or other liquid,
or aqueous vapour, at a temperature lower than that of the effluent gases, and in
regulated quantity, at, or near, the outlet for the gases escaping above the charge
in the oven, furnace or retort, by which the gases pass, or are withdrawn, so that
the gases as they pass thereto, or thereinto are cooled and moistened and pitchy,
or heavy tarry matter is prevented from accumulating in the outlet passages and it

or in a considerable degree preventing the decomposition thereof.
Figure 1 represents the top of a coke oven,
Figure 2 represents the top, of a vertical retort, or furnace, such as those used
for instance as blast furnaces; and
Figure 3 shews one end of an ordinary gas or shale retort all with my invention
applied thereto.
In all these figures a is a pipe by which water or liquid at a temperature lower
than that of the effluent gases is admitted as hereinbefore described. The pipe is
preferably arranged with an open part at b which constitutes a sight feed and has,
between this sight feed and the inlet end, a liquid seal constituted by the bent
part c. d is a valve for regulating the supply. e Fig. 3 are removable plugs to
permit of a wire being inserted to clear the pipe c.
Although I have shewn the sight feed and liquid scaled supply pipe and but one
pipe yet it is to be understood that I do not limit myself to that form of supply
pipe nor to the use of oue pipe as the liquid or aqueous vapour can be supplied
by any convenient arrangement of pipe or inlet and any number of such pipes or
inlets may be used.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
In ovens, furnaces, or retorts, used for the making of coke, or charcoal, or for
distilling, or roasting, carbonaceous matter, or otherwise subjecting carbonaceous
matter to the action of heat; means for supplying water, or other liquid, or
aqueous vapour, at a temperature lower than that of the effluent gases, and in
regulated quantity, at or near, the outlet for the gases escaping above the charge;
substantially as, and for the purposes herein before described.
