The fire behavior of materials provides valuable information for
evaluating the behavior of samples and their components.
The furnace can be used to evaluate the fire resistance of products
such as walls, doors, dampers, joints and permeable seals.This is
done by calculating the inclusion;Test the carrying capacity, fire
resistance and thermal transmittance of the components.
The system features:
1. A specimen restraint frame mounted on the front end of the
furnace and secured by a minimum of 4 sets of door clamps.
2. A steel casing lined with mineral fibreboard on the cold face
and refractory insulating bricks anchored back to the wall with
high temperature cast in-situ blocks, on the hot face.
3. 4 sets of viewing ports made of heat resistant quartz glass are
provided at strategic locations on the long side wall. This will
enable the operator to view the complete test specimen during a
4. A sliding door made of light weight alumina is enclosed within
an insulated, air-cooled frame. This will shield off the furnace
heat when the viewing ports are not in use.
5. 12 sets of Special Luminous Flame Burners. Every burner has a
flame supervision unit to ensure that all combustion units operate
on a fail safe mode at all times.
6. Furnace Combustion Control Panel is designed to operate on both
fully automatic and manual control modes. Automatic ignition of the
burners is through the use of one push button switch, this, fires
up the burners based on a preset heating curve, as described in BS
476 Parts 20-24, EN 1363 and the IMO Hydrocarbon Curve. Manual
burner control enables individual burners to be ignited at will.
7. A Fire Resistance Test Furnace with an internal chamber
measuring3000mm(W) x 3000mm(H) x 1300mm(D).
8. The capability to carry out test on Vertical Test Specimens that
are mounted on custom made restraint frames.
9. Refractory lining is comprised of insulating fire bricks,
refractory castables and mineral boards.
10. A roof lined with profiled bricks and anchored with
refractories cast in situ.
11. A casing made of mild steel plates reinforced with steel
C-Channels, I-beams and steel sections to counter structural
distortion due to heat.
LP Gas Industrial Refractory Luminous Soft Flame Burners
In the upright furnace position, 6 burners are installed on each of
the left side and right side of the furnace wall. Each burner is
designed to use liquefied petroleum gas and all of the necessary
flame safety systems, intermittent pilot systems, and temperature
sensors are incorporated.
Lifting Frame and Restraint Frames for Test Specimens
Two units of Frames are supplied for mounting vertical specimens.
The refractory lining is made of pre-cast refractory blocks,
anchored to the steel frame. These frames are non load bearing
frames. A separate customized lifting frame with two side hooks is
provided to lift the specimen restraint frame to the furnace. This
allows easy placement of the vertical and horizontal restraint
frames into the furnace.
Refractory Lined Connecting Duct And Exhaust Stack
The Chimney/Stack is constructed of 9mm thick mild steel and is
refractory lined for the first 6 metres. The Stack extends to a
minimum of 3 metres above the factory roof level or in accordance
to the local Code requirements.
Combustion Air Blower to Furnace Burners
The combustion air system is pre-piped and tested before dispatch.
Temperature Sensors and Manometer
The system is supplied with 9 Type K thermocouples and plate
thermometers, a pressure manometer and an ambient thermocouple
The PLC System is comprised of a Siemens PLC CPU and Siemens
compatible remote I/O. The fire resistance data management software
is custom written to accept and save data collected during the
tests and is configured to meet the heating requirements of BS 476
Parts 20 - 22, EN 1363 and IMO Hydrocarbon test curve.
Other standard Time-Temperature curves can also be pre-programmed
into the system. The PLC controller incorporates a built-in
operator interface, contains the required recording and programming
capabilities and includes all necessary motor starters for all
motors in the system. The system is programmed to provide real time
heating curves and display all furnace control information on the
