CD any wall at the rear Of the
CRATE or stoker that acts al q de-
hector and radiant heat reflector for
the furnace gases. and as q stop Tor
the fuel bed or rear wall OF the ash
pit.
Damper-
(g) any device placed In the
breeding of boiler before the stack
Is reached, or In a smokestack, to
regulate the draft pressure or escape
OF furnace gases.
Smoke Indicator
(h) any electric, mechanical or
other device. sky-light, window or
rejecting convex mirror or series or
mirrors, or breeding indicator that
will allow the person firing the boiler,
or other fuel-burning vessel, to see,
from the boiler room, the density and
color of the smoke being emitted
from the top Of the chimney or stack
or other conduit.
Smoke Abatement Devices
Cd any apparatus (steam or motor
driven) air-carrying pipe-Or set OF
such pipes-attached to a steam boil
er, so arranged as to provide sauxil-
liary air, for turbulence, over the
fuel bed to promote the combustion
process
Heating Surface
Cd any boiler surface having
water on one side and hot gases on
the other. not excepting any surfaces
that are covered by the arches, or
tile. used in the construction OF the
boiler furnace.
Furnace Volume
(k) is that volume above the fuel
bed and in front of the bridge wall.
In case of fire-box boilers II is that
volume measured to the front tube
sheet or the first row Of tubes.
Wing WALL
Cd any fire brick construction,
built inside boiler furnace, or other
furnace that serves as a def1ectOr Of
| the gasses in the combustion cham
Der, and as means of providing
radiant heat TO aid combustion proc
esses
Ignition Arch
(m) any fire brick constructed
arch that serves, via radiation, to
hasten the igniting of the furnace
gases to aid combustion.
Extension Furnace
(n-Dutch Oven) any masonry or
other structure, built on the front of
a boiler, or other vessel. for the pur-
pose of obtaining additional furnace
volume.
Cleaning Fires
Coz the act of removing clinkers
and /or ash from the fuel bed This
does not mean shaking down the
| fire"
(p) the act of building up a fuel
| bed when there is no fire on the
CRATE and the boiler is in cold con-
dition. 1t does not mean replenishing
the fire with fresh coal.
Dust Collectors. Mechanical
Collectors, etc
are defined as being:
(D Cyclone Centrifugal Effect Col
lectors; Filters: Screen-clOth (bag
type) wet type; Contact Impact
Baffled-Adhesive, etc. Washers
Spray Centrifuge type-Filter tow
ers, etc. Electrical PrecipitatOrs:
Gravity type-Dust Chambers, etc. {;
Verticose Effect Collectors internal
vortex Whirlwind or Tornado for
use on dryers. kilns. waste heat boil
ers, clinker mills and matchmaking
elevator conveyors, etc.
SmOkeless Furnace
(r) a smokeless furnace shall be
considered as one in which cOmbus-
tion is completed before the products
of combustion reach the heating sur
! faces of the boiler.
Ord the surface-burning type of
coal-burning furnace is defined as a
/ hand-fired furnace in which the fresh
fuel is thrown directly on the hot
fuel bed.
Boilers
Isl /. all boilers carrying more
than fifteen (15) pounds pressure
per square inch shall be classed as
power boilers, and ten 10) square
feet of heating surface shall be count
ed as one Cd horse power.
(s) 2. Power boilers. installed for
heating purposes. shall be rated at
one hundred (14O) and forty square
feet of radiation capacity for each
horse power.
3. Boilers used for the purpose of
heating by means OF hot water shall
be based on p times the capacity
ratings. given above, for steam heat
: ing boilers.
ChinneyS or Stacks
! The Department shall have the
power to require the frightening or
alteration of any chimney or stack
that may prove TO be creating nuis-
ance to surrounding property. Said
extension must have the same area
as the chimney or stack involved.
Screens (where required)-
Sizes and Heights
The emission of sparks or fire
brands from chimneys shall be ar
rested with screen guards not less than
| " inch square mesh. The height OF
the sides shall not be less than the
smallest size Of flue. Sizes of fiues
and the height of same may be gov
erned-as necessarily the require
ments of boiler manufacturers, or
recognized authorities. via official
handbooks or data sheets-all as
mentioned in Section 8 of this Code,
The minimum area for domestic fiues
shall be As square inches for stoves
and not less than 65 square inches
for furnaces. Fireplace flues shall
have an area of 10th lone tenth
of said fireplace opening. Flues less
than 20 feet in height-from CRATES
shall be increased in area. In me-
chanicany fired heating boilers or
