IMPROVEMENTS IN STEAM GENERATORS
Year: 1885

page_text: I, WILLIAM CLARKE, of the Victoria Works, Gateshead on Tyne, in the County
of Durham, Engineer, do hereby declare the nature of said invention for
"IMPROVEMENTS IN STEAM GENERATORS" to be as follows:-
My invention relates to an improved form of vertical steam generator and is
designed to obtain increased efficiency in the generation of steam and economy of
fuel also simplicity of manufacture and accessibility for cleaning and repairs.
In a cylindrical vertical shell I arrange a firebox prolonged upwards at the side
opposite the fire door to form a combustion chamber. The front side of this
upward extension of the fire box is made to form an inclined tube plate, and a
similarly inclined tube plate is attached to the vertical shell. In these tube plates
are fixed a series of inclined flue tubes, through which the heated gases pass to the
outside of the shell where there is a smoke box of any convenient form connected
with a chimney in the usual way. By the arrangement of the flue tubes at an
angle as described the draught is improved and the efficiency of the tube heating
surface is increased. The junction of the lower part of the shell to the firebox is
so arranged that the seam shall be always accessible whilst the boiler is at work.
To this end the shell at its lower part is flanged inward so as to fit around the
outside of the fire box.
To obtain more complete combustion of fuel gases there is or are fitted to the
upper part of the combustion chamber one or more tubes which is or are led down
through the water space and connected at its or their lower end or ends to the
lower part of the fire box just over the fire so that unconsumed gases in the upper
part of the firebox can pass downward by the tube or tubes and thence over the
fire to be thereby ignited and consumed.

page_text: I, WILLIAM CLARKE, of the Victoria Works, Gateshead-on-Tyne, in the County
of Durham, Engineer, do hereby declare the nature of my 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 an improved form of vertical steam generator and is
designed to obtain increased efficiency in the generation of steam and economy
of fuel, also simplicity of manufacture and accessibility for cleaning and repairs.
Figure 1 of the annexed drawings is a vertical section of a steam generation
according to my invention; Figure 2 is an elevation of the same at right angles
to Figure 1. Figure 3 is a part elevation of the firebox and Figure 4 is a horizontal
section.
In a cylindrical vertical shell A, I arrange a fire-box B prolonged upwards at
the side opposite the fire-door opening C to form a combustion chamber D. The
front side of this upward extension of the firebox is made to form an inclined tube
plate E, and a similarly inclined tube plate F is attached to the vertical shell A.
In these tube plates are fixed a series of inclined flue tubes G through which the
heated gases pass to the outside of the shell A where there is a smokebox of any
convenient form connected with a chimney in the usual way. By the arrangement
of the flue tubes at an angle as described the draught is improved and the efficiency
of the tube heating surface is increased.
The junction of the lower part of the shell to the firebox is so arranged that the
seam shall be always accessible whilst the boiler is at work.
To this end the shell at its lower part is flanged inward so as to fit around the
outside of the fire box, as illustrated at H.
To obtain more complete combustion of fuel gases there is or are fitted to the
upper part of the combustion chamber D one or more tubes I which is or are led
down through the water space K and connected at its or their lower end or ends
to the lower part of the firebox just over the fire so that unconsumed gases in the
upper part of the firebox can pass downward by the tube or tubes and thence over
the fire to be thereby ignited and consumed.
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
The vertical steam generator with inclined fire tubes-as described and shewn,
whether with or without a tube or tubes such as I, for the purpose specified.
Dated this 23rd day of October 1885.
