Improvements in Steam Generator and other Furnaces.
I, JAMES FERNEE of Chantrey Road Norton Woodseats in the County of Derby
(near Sheffield) Gas Furnace Manager do hereby declare the nature of this invention
to be as follows:-
--
My present invention relates to Steam Boiler and other Furnaces especially to
Marine and Locomotive Boilers.
Instead of allowing a great portion of the best of the fuel to escape unburned up
the Chimney, I propose to convert the fire boxes into Gas Generators within or
under the Boilers, by covering in the lower portion of the Fire Box or Furnace
Chamber with a perforated roof consisting of fire clay material or of metal leaving
the perforation or perforations large enough to admit of vertical tapered air flues
which also consist of Fire Clay Material or of Metal, the said flues are arranged to
pass up through the firegrate and through the fire and into or through the Gas
Generator roof, the perforations in the fire Grate for the fitting of the said air flues
and the perforations in the Gas Generator roof for the insertion of the upper end of
the said air flues are similar in size the taper at the upper-ends of the air flues which
are of Sugar loaf form leaves sufficient annular spaces around them for the egress of
the Gas from the gas generator it coming in contact with the Air at this point which
is also the initial point of combustion. The apper surface of the Gas Generator
roof forming the Floor of the Combustion Chamber the lower ends of the air flues
are arranged bell shaped with simple valves for accumulation and regulation of the
heated air for the combustion of the Gas or instead of which is arranged along th
centre of the Gas generator a hollow tapered bridge for the accumulation of heated
air with outlets at or near its upper surface for. the Combustion of the Gas in the
manner aforesaid.
Or I arrange the Gas Generator roof with numerous perforations and the vertical
air flues without the annular spaces around them or the following arrangement
namely, that the end wall of the Gas Generator be perforated in addition to the
roof and a passage or passages be arranged at or near the said end wall for the
purpose of receiving air to be conveyed through a perforated wall or metal
plate situated beneath and at the back part of and for the support of the fire
grate bars.
The Gas generator has a close fitting door at its upper part, it is fitted temporarily
or permanently with a hopper for the purpose of charging small coal or slack into
the Gas generator small apertures are arranged in the door for the manipulation of
the fuel similar to the working of ordinary Gas Producers.
GAS COMBUSTION CHAMBER AND THE REGULATION OF THE HEAT.
The Combustion Chamber which is immediately above the Gas generator is
arranged in the following manner the heat regulator is a long light metal frame
arranged with brick and space and slides horizontally partially or wholly shutting off
the flame and thus regulating the heat as well as the pressure of steam, in the
Combustion Chamber is a perforated bridge wall for the purpose of assisting
in the accumulation of heat and to steady the working of the Gas generator.
PREPARING FOR MAKING GAS.

But while this Operation is going on the Boiler is being heated in the usual way by
the indraught of air through the fire grate and the outlet of the heat generated to
the Gas Combustion Chamber through horizontal slide dampers arranged for that
purpose in Gas generator roof the gas generator fire may be worked by natural
draught or under pressure as the case may be. It will be at once seen that this
arrangement applied to Lancashire or Cornish Boilers gives up to these boilers not
only the heat of the Gas Generator fire but the intense heat of the heated
air and Gas in combustion produced, which also renders boiler firing perfectly
smokeless.

COMPLETE SPECIFICATION.
Improvements in Steam Generator and other Furnaces:
JAMES FERNEE Chantrey Road Norton. Wood seats in the county of Derby Gas
Furnace Manager 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 present invention relates to Steam Boiler furnaces and other heating purposes
especially to Marine and: Locomotive boilers. Instead of allowing a great portion of
the best of the fuel to escape unburned up the chimney stack I propose to convert
the fire boxes into gas generators by covering in the lower portion of the fire box or
furnace Chamber or Chambers with a perforated. roof consisting of metal or of
fire clay material with a. perforation or perforations to admit. vertical air flues which
also consist of metal or fire clay material and are arranged to pass up through the
firegrate bars through the fire and into or through the Gas generator roof, the said air
flues are of tapered form and sufficient annular space is allowed. at and around their
upper ends for the egress of Gas while the heated air is issuing at this point which
is the initial point of combustion. It will be seen that the upper surface of the
Gas generator roof forms the floor of the Combustion Chamber or Steam generator
the air flues are fitted at their lower ends with simple valves for the regulation. of
the air supply for the combustion of the Gas. Or instead of which is arranged
along the centre of the fire grate one long air receiver with outlets at its upper part for
the combustion of the Gas in the manner already described.
The Gas generator is arranged with a close fitting door with charging, hopper
at its upper part for the distribution of small coal or slack. on to its fire,
the manipulation of the fuel is carried on: through perforations in the, gas
generator door similar to the working of ordinany gas producers..
The gas
generator may be arranged with numerous perforations in the roof and air flues
with or without annular spaces or the following arrangement namely that the
upper part of the end. wall of the gas. generator may be perforated, and a passage
or passages be arranged at or near the said end wall for the purpose of receiving
air to be conveyed. through: a perforated wall or metal plate situated beneath and
at. the back part of and for the support of the fire grate bars.
THE GAS COMBUSTION: CHAMBER OR STEAM GENERATOR AND THE REGULATION OF
THE HEAT THEREIN..
This arrangement consists of a metal frame kept clear from the action of the
flame and is fitted with thin firebrick and. space corresponding with the flame
ports, this sliding arrangement may be worked forward or backward partially or
wholly shutting off the flame; the chimney flue in the combustion. chamber is
arranged with a perforated or chequered wall this is to give tone to the working
of the gas generator and for the retention of the heat generated.
