FURNACE PROTECTOR
FIELD OF THE INVENTION
The present invention relates, generally, to Furnace Protectors. More
specifically,
the invention relates to Furnace Protectors that are purposed to be used to
protect
selected components of a furnace.
BACKGROUND OF THE INVENTION
Furnaces, in particular oil furnaces, have many parts and associated
components
that require protection from moving articles. This is because damage to such
parts
or components may lead to an environmentally unfriendly situation, such as an
oil
spill. Some parts may include the oil filter, carburettor, motor and
electrical
components. An associated component may include an oil barrel which may be
attached to a furnace. tWoday's society for FurnaCe r PIrU toCC_t_lUrr_S
auC1%A1UU to 1 IICIC is a need III Ud~/ J I Furnace
that can be mounted to a furnace assembly or an affiliated region wherein
sensitive components can be protected. The prior art has attempted to address
this need.
For example, Chinese Patent Application No. 2806464Y discloses a furnace
protective device for coke furnaces comprising a door frame and protective
plates
for burning chamber, checker chamber and chute zone. The protective device has
a reasonable structure, high strength, and provides good sealing effect and
protection for the furnace body.
Canadian Patent No. 1,105,976 discloses an electric heater assembly, having
electric resistance heating elements and refractory structure for supporting
the
electric resistance elements. The refractory structure includes flanges that
serve
as shielding for the heating elements from material which may fall from above
in
the furnace.

United States Patent No. 4,085,726 discloses an arrangement for protection
against damage to electric motor lead wires during servicing of furnace
components within the furnace cabinet. The invention contemplates the
provision
of an electrical junction box mounted on blower support plate and of a channel
shaped raceway provided with means for holding the electrical leads along the
channel.
Chinese Patent Application No. 201268676Y discloses a cover block for coke
oven brace grooves. The cover blocks are connected and laid on the brace
grooves so as to discharge the water deposited on the furnace top to prevent
it
from leaking into the furnace brace grooves.
Chinese Patent Application No. 2205534Y discloses a protector for working in
front of a metallurgical furnace comprising three truckles, upstanding
protective
wall, armrest handles and other means to satisfy various needs of working in
front
of c a metallurgical furnace.
The prior art as of yet does not envisage or indeed teach a Furnace Protector
that:
1. Provides protection of furnace parts and associated components that
require protection from moving articles, while providing access to these
parts / components;
2. Provides protection of furnace parts and associated components that
require protection from moving articles, while providing visibility to these
parts / components;
3. Provides a mountable means for protection.
A furnace protector according to the present invention may be constructed to
provide some protection for all of the elements of the furnace motor, not
simply
2
CA 02714320 2011-02-08
electrical connections or other single or limited elements as in the prior
art. It is a
construction which is an easily removable or adjustable device suited to a
wide
range of applications, and is not limited in use to industrial size
applications. It
provides better protection than the prior art. Unlike the greater part of the
prior art
it is useful in personal/residential, commercial or industrial environments.
The optimal permanent mounting of the invention inhibits the possibility that
the
protector can itself cause damage through movement after being hit by a moving
object.
The furnace protector according to the present invention may in general be
normally less weighty than the prior art and more convenient to install by a
prudent individual of average ability and with diligent and purposeful
application.
The present invention was conceived and developed having regard to the known
prior art and with the purpose of providing an improvement in the art of
Furnace
Protectors.
