do hereby declare the nature of my invention for IMPROVEMENTS IN APPARATUS
FOR THE CONDENSATION AND ABSORPTION OF THE PRODUCTS OF COMBUSTION FROM
COAL OR OTHER GAS OR OIL USED EITHER FOR LIGHTING OR HEATING PURPOSES
to be as follows:-
My Invention bas for its object the entire condensation and absorption of the
products of combustion, and enables me to burn Gas or oil without any chimney
vent or flue and without damage to the air of the room or apartment in which it
is so burnt. I propose to apply my principle particularly to open fire Asbestos, or
clinker gas or oil burning Stoves, or Grates, or to Steam or Hotwater Boilers or to
the heating of any fluid for which gas or oil would be a convenient fuel, The
apparatus is also available as an attachment to any chandelier or other light giving
gas or oil burner, and is applicable to gas heated Ovens and Cooking Apparatus.
For the carrying out of my Invention I take any suitably constructed gas or oil
heated Stove, gas fire, Grate, Oven Steam Boiler, Hot water or fluid heater, Stove
or boiler, or gas or oil burner, and convey the whole of the products of combustion
into one or more condensers, which condensers may be hollow spaces forming the
backs or sides of fire places or stoves, or may be tubes or coils, & may be constructed
of metal or any other suitable material. These condensers are to be exposed to the
cooling influence of the air, or may be partly or wholly immersed in water or other
fluid so that by the cooling of the products of combustion they act in a certain
syphoning manner to draw off the burnt gas or oil fumes from the stoves or other
apparatus such as before described.
I intend to provide proper receivers for the condensed liquid, and the dry air
from the condensers may then be conducted through chambers containing lime or
caustic soda or any other suitable absorbent material either dry or mixed with
water or in solution, and the air ultimately escaping shall not be injurious to
health.

page_text: I HENRY HERBERT HAZARD, of 5 Park Side, Knightsbridge, London, Middlesex,
Engineer, do hereby declare the nature of iny said Invention for "IMPROVEMENTS
IN APPARATUS FOR THE CONDENSATION AND ABSORPTION OF THE PRODUCTS OF
COMBUSTION FROM COAL OR OTHER GAS, OR OIL, USED EITHER FOR LIGHTING OR
HEATING PURPOSES" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
My invention has for its object the entire condensation and absorption of the
products of combustion, and utilisation of the beat arising from such combustion;
and enables me to burn gas or oil with or without any chimney, vent, or flue, and
without damage to the air of the room or apartment in which it is so burnt.
I apply my invention to Open-fire asbestos or clinker gas or oil stoves or grates;
and to steam and hot-water boilers when heated by Gas or Oils; and to the heating
of any fluid for which gas or oil would be a convenient fuel. The invention is
also available as an attachment to any chandelier or light giving gas or oil burner,
in order to absorb and prevent the diffusion of the deleterious products of
combustion, and to utilise the heat arising therefrom (if desired). My invention is
also applicable to gas heated ovens and cooking apparatus.
In carrying out my invention, I convey the whole of the products of combustion
into one or more condensers.
In forming these condensers I avail myself of any necessary adjunct to the stove;
such as the sides, back, top, front or other parts of the stove or chimney piece
ornamental or otherwise, and make such parts hollow, and of metal, in order that
they may act, not only as recipients for the deleterious gases, and the condensation
of the mixture of carbonic acid, oxygen, and nitrogen, but also that they may
conduct the uncontaminated heat to the surrounding atmosphere, or where else it
may be required.
Šuch condensers are made in various ways to suit the purpose and surrounding
arrangements; and, in some case, are whole or partially immersed in water or other
fluid in order to condense quickly.
When using a small flue or pipe to carry away some of the spent gases, the
entrance to such flue is made as near the floor as possible, in order that the coolest
of the gases only may pass away.
In cases where no fue is used, the products of condensation are gathered collected
and absorbed in suitable vessels, which are supplied, from time to time, with caustic
soda, or lime, or caustic soda and lime in combination.
In applying my invention to the heating of steam boilers, hot water boilers,
cooking stoves, and analogous purposes, the heat arising from the combustion of
the gas or oil is utilised for such purposes, the caloric being thereby absorbed, and
rendering any additional condensing apparatus unnecessary, and the application of
the absorbent materials completes the process.
And in order that my said Invention may be clearly ascertained, reference is
hereby made to the accompanying drawings which are intended to be merely
illustrative, and not exhaustive, of the methods of applying my said invention to

page_text: the purposes herein before described or referred to; and in which similar letters of
reference indicate corresponding parts.
-
The
Fig 1. is a section of an ordinary Gas stove fitted with one form of my
invention a is the stove, b is an ordinary horizontal Bunsen burner, c is a slab
of fire clay, d is a mass of asbestos or other suitable material, which becomes
incandescent when the gas is lighted. The heat arising from the combustion of the
gas is first communicated to the upper part of a, and a large portion of this heat
is thereby communicated by conduction to the air of the apartment.
remainder of the products of combustion, at a reduced temperature, passes through
the tube e to the condenser f, This condenser f may be of rectangular form (as
shewn) or of any other convenient shape, or formed entirely of tubes, whereby a
large beating and conducting surface is exposed to the air in the apartment, and
which air is thereby warmed. The passage e is sometimes passed through a wall
or partition; by which arrangement the stove a may be placed in one room and the
condenser fin another, whereby two rooms are warmed with one firc.
In Fig. 1 my invention
shown with a chimney or flue i. The pipe g conveys
the condensed water to the receptacle k.
In Fig. 2 the invention is shewn without the chimney or flue i
In this Fig. 2 the pipe g³ carries the cooled products of combustion to the
receptacle h, which carries a perforated diaphragm and tray h¹, in which the
absorbing material is placed to disinfect and absorb any carbonic acid, and other
gases, which may remain after condensation of the gases and extraction of the
caloric by conduction.
Fig. 3 is a perspective view of the stove & and condenser f as ordinarily
constructed.
Fig. 4 shews the application of my invention to heating the water for a bath;
or other analogous purpose. b is the burner, is the water heater, gl is a pipe
which conveys the remainder of the heated gases to the coil g in the cistern l.
is a box, having the tray h' for the absorbing material, o is a pipe conveying the
partially heated water to the water heater k.
Fig. 5 shews the application of my invention to ordinary or other gas burners m m.
The products of combustion are conveyed away by and condensed in the pipe f
leading to the absorbing chamber h, which may be placed in any convenient
position; the condensed liquid being carried away by the pipe n into a drain.
But in some cases I pass the cooled products of combustion into a chimney.
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 method and means of utilising the heat arising from the combustion of
the fuel, and condensing the deleterious portions of the gases, previously to their
passage to the flue, substantially as described and shewn on the drawings.
2 The method and means of absorbing the deleterious portions of the gases, by
means of caustic soda or lime, or caustic soda and lime in combination, and thereby
dispensing with a flue, substantially as described and shewn on the drawings.
3-The general combinations and arrangements of the several and respective
parts together forming my improvements in apparatus for the condensation and
absorption of the products of combustion from coal or other gas, or oil, used either
for lighting or heating purposes, substantially as described and shewn on the
drawings.
