IRON FIREMAN Automatic Coal Burners
"Forced Underfiring" Principle
--Iron Fireman "Forced Underfiring"
is based on the scientific principle of
feeding fuel to the fire from below,
under forced draft. From the con
veyor screw coal enters the firebox
under the fire and is gradually forced up
ward into the flame. As the coal ap
proaches the fire, it is gradually heated.
The volatile gases are distilled off in the
presence of an excess of oxygen and are
thoroughly ignited while passing through
the incandescent fuel bed. This insures
complete combustion. The ash is fused
into clinkers which are easily removed.
Advantages--Iron Fireman saves
money and in
creases heating
plant efficiency in
four major ways:
(1) Cuts fuel
costs; (2) Reduces
labor costs; (3)
Provides steady, Typical Installation Down

Draft Firebox Boiler
power; (4) Elimi
nates the smoke nuisance.
Installation and Sizes--Iron Fireman
is made in a range of hopper and bin-feed
sizes for commercial heating and power
boilers up to 300 b.h.p. and also for homes.
It can be installed quickly in practically
any solid fuel boiler or furnace, old or new.
Machines are shipped complete from the
factory. All parts are standard and
interchangeable.
Features of Design and Construc
tion--Construction and operation of the
Iron Fireman are characterized by sim-
plicity throughout. Outstanding fea
tures of design and construction, are:
(1) Pressed steel construction. (2)
Special patented transmission--three
speeds and neutral. Gears run in bath
of oil. (3) Electric motor--standard
make. (4) V-belt drive. (5) Safety shear
pin protects mechanism from damage. (6)
Quiet ball bearing fan supplying forced
draft to fire. (7) Automatic fire banking
damper--conserves fuel and holds fire in
proper condition when stoker is idle. (8)
Positive pneumatic fume eliminator--an
auxiliary air supply that insures positive
movement of all gases through the fire.
(9) Volumeter that supplies exactly the
amount of air needed for perfect com
bustion regardless
of fuel bed con
ditions or type of
coal used. (10)
Sectional retort
especially design
ed to allow for
heat expansion..
(11) Dead plates
of heavy iron and ribbed. (12) Sec tional, self-clean ing tuyere blocks.

for and used exclusively on Irpn Fireman.
Automatic Controls--Iron Fireman
starts and stops at the command of sensi
tive, accurate automatic controls. Direct
ing controls govern stoker operation

ture, or pressure. An example of the
superiority of Iron Fireman directing con
trols is the " Syncro-Stat " which provides
automatic control of day and night tem
perature. Other directing controls include
pressure regulators, hot water and furnace
regulators, and the "Timetactor," a device
which runs the Iron Fireman during pre
determined intervals in order to keep the
fire alive during mild weather.
The most important unit of the oper
ating control system is the motor-driven
relay switch. This
device starts and

motor at the com-
mand of the

other directing
controls. In the

works in conjunc
tion with the relay switch.
Iron Fireman for Homes--The Iron
Fireman residential model employs "Forced
Underfiring" principle-the same as larger
machines, with simplified operation.
Can be recommended for any steam, hot
water, vacuum, or warm air furnace. Quickly installed. Hopper and binfeed models for both bituminous and anthracite coal. Anthracite models have been tested and ap proved by The Anthracite Insti tute.
