§ 27-836 Refuse collection rooms. A refuse collection room shall be
provided for refuse reduction systems which utilize methods other than
burning. Such rooms shall comply with the requirements of section 27-837
of this article.
a. Existing refuse rooms and incinerator rooms which have been
approved for such use, may be retained as approved.
b. Existing incinerator combustion chambers may be used in whole or in
part as refuse collection rooms provided the grates are removed and
provided they comply with the provisions of section 27-837 of this
article.
c. Floors of refuse collection rooms shall be constructed of concrete
and shall be sloped to a floor drain within the room, connected to the

Compacting equipment shall be arranged to operate automatically when the
level of refuse is not more than three feet below the lowest hopper
door.
Section 27-837
§ 27-837 Incinerator rooms. Incinerators and refuse collecting bins

manner so as to prevent warping, binding, cracking, corrosion, and
distortion when exposed to operating temperatures. If an automatic draft
controller is used, means shall be provided for temporary manual
operation.
Section 27-840
§ 27-840 Charging chutes and exhaust flues. All incinerators shall be
constructed with a flue within a chimney to exhaust the products of
combustion and a refuse charging chute which shall be separate from the
flue. Refuse charging chutes shall not discharge directly into
incinerators, except in buildings classified in residential occupancy
group J and in accordance with the requirements of this subchapter and
subchapter fifteen of this chapter.
Flues for existing incinerators and existing refuse chutes may be used
as refuse charging chutes provided they are in good condition and comply
with the requirements of subchapter fifteen of this chapter.
Section 27-841
§ 27-841 Charging gates. Charging gates, when provided, shall be power
operated. Gates and guide rails shall be of such materials and

provided for all incinerators. Such heat sources shall be capable of
maintaining a temperature of at least fifteen hundred degrees Farenheit
at the discharge from the combustion chamber, and shall be equipped with
safety devices to shut off the fuel in cases of ignition failure, flame
failure, or insufficient draft.
Section 27-843
§ 27-843 Construction of incinerators. Incinerators shall be
constructed so as to be gas tight and shall be lined or protected with
heat resistive materials suitable for the services required, as follows:
(a) Masonry incinerators. When the combined hearth and grate area is
twenty square feet or less, or the number of habitable rooms served is
one hundred or less, combustion chambers, separation chambers, and
connecting gas passages shall be constructed of eight inch common brick
thick and lined with four and one-half inch of refractory material with
an intervening air space of one inch. When the combined hearth and grate
area is more than twenty square feet, or the number of habitable rooms
served is more than one hundred, combustion chambers, separation
chambers, and connecting gas passages shall be constructed of common
brick eight inches thick and lined with nine inches of refractory
material with an intervening air space of one inch.

course of common-brick. Structural steel angles, straps, and tiebacks
shall be installed on all masonry incinerators having more than one
hundred twenty-five cubic feet of combustion chamber volume.
(2) INTERIOR CONSTRUCTION. Interior walls, curtain walls, bridge
walls, or baffles shall, in every case, be of refractory brick, at least
nine inches thick.
(3) ARCHES. Sprung arches may be used if the span is less than four
feet Flat suspended type arches shall have a minimum of five inches of
refractory material between the furnace heat and the hangers. Flat
suspended arches shall have an insulated block roof at least two and
one-half inches thick.
(4) ISOLATION. No structural supports for the vertical building flues
or other parts of the building shall rest upon the incinerator; nor
shall any metal guides, hangers, or structural steel parts of the
incinerator be exposed to direct heat of combustion.
(5) THERMAL BLOCK INSULATION. High temperature block insulation shall
