PROVISIONAL SPECIFICATION.
A New Means or Method of Generating Heat by the Use of Spent
Gases arising from Furnaces.
We, GEORGE HENRY HIRST, JOSEPH HIRST, and ARTHUR HIRST, trading as
George H. Hirst and Company, of Alexandra Mills, Batley, in the County of
York, Manufacturers, and ALFRED BEAUMONT, of Mill Lane, Soothill, Batley,
aforesaid, Engineer, do hereby declare the nature of this invention to be as
follows:-
Our invention refers to a new method or system of creating hot air, and this we
propose to do by the aid of spent gases arising from the furnaces of steam boilers
and other description of furnaces.
According to our invention we place behind a furnace, say in the fine or other
suitable and convenient place, an arrangement of pipes arranged vertically or other-
wise, together with air boxes or chambers, the whole being so arranged that the spent
gases will impinge against the raid pipes whereby they become heated. Atmospheric
air is forced or drawn through the series of hot pipes, which air becomes intensely
heated on passing through the said pipes. Hot air thus produced is afterwards
conveyed by piping to machinery or rooms requiring to be heated. Hot air thus
produced will be found of great advantage in tentering machines, wool-drying
machines, carbonizing machines and for disinfecting fabrics; also in machines
employed for drying textile fabrics, yarns, and fibres.

A New Means or Method of Generating Heat by the Use of Spent
Gases arising from Furnaces.
We, GEORGE HENRY HIRST, JOSEPH HIRST, and ARTHUR HIRST, trading as
George H. Hirst and Company, of Alexandra Mills, Batley, in the County of
York, Manufacturers, and ALFRED BEAUMONT, of Mill Lane, Soothill, Batley,
aforesaid, 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 :-
Our invention refers to a new method or system of creating hot air, and this we
propose to do by the aid of hot gases arising from the furnaces of steam boilers and
other description of furnaces.
According to our invention we place behind a furnace, say in the flue or other
suitable and convenient place, an arrangement of pipes arranged vertically or other-
wise together with air boxes or chambers, the whole being so arranged that the hot
gases will impinge against the said pipes whereby they become heated.
Atmospheric air is forced or drawn through the series of hot pipes, which air
becomes intensely heated on passing through the said pipes.

page_text: In order that our invention may be more fully understood, reference is made to
the accompanying sheet of drawings, wherein A represents a steam boiler having
furnace B. At the rear of the said boiler a chamber C is formed, compo-el of
brickwork or other suitable material in which we place a series of pipes D_com-
municating at each end with air chambers E. The air is generated by a Root's
blower or other form of fan and forced through the said pipes D. finally passing
out through pipe G. It will be seen and readily understood that the hot gases
arising from the furnaces will impinge against the said pipes D and air boxes E
consequently the air passing therethrough will be intensely heated and may be
conveyed by suitable piping to machinery or rooms requiring to be heate 1.
the hot gases have impinged against the pipes D they pass away in the ordinary
course through opening J to the chimney.
After
Hot air thus produced is pure and free from gases, sulphur and other impurities,
and will be found of great advantage in tentering machines, wool drying machines,
carbonizing machines, and for disinfecting fabrics; also in machines employed for
drying textile fabrics, yarns, and fibres, also for drying earthenware articles
previous to burning or other purposes where heat is required.
The characteristic feature in this invention consists in utilising the hot gases
arising from boiler or other furnaces whilst travelling from the furnace to the
chimney.
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 :-
The utilisation of waste heat and gases arising from steam boiler furnaces for
heating pure air drawn or forced through pipes, the said hot air being afterwards
used for drying and similar purposes all in the manner substantially as shewn in the
drawings and described herein.
Deted this 8th day of July 1895.
