BS EN 1634 Vertical Fire Furnace
Test standards:
A vertical test furnace applies for four industries: building
materials, fire protection, rail transportation, and shipping.
The vertical test furnace complies to the following test standards:
UL 10C-2009
EN1363-1-2012: Fire resistance test-Part 1: General requirements
EN1364-1 / 3: Fire resistance test of non-load-bearing wall
components-part: wall / curtain wall
BS476-21-1987
ASTM E119-11
BS EN 1634
ISO834-1 / 8
GBT 9978.1-2008: Fire resistance test methods for building
components Part 1: General requirements
GB / T 26784-2011: Fire resistance test of building components

Furnace Shell:
The furnace shell and furnace steel plate material is selected Q235
steel which is in accordance with the requirements of the
"Industrial Furnace Design Manual".
Anticorrosive treatment scheme:
high temperature touch part:
- High-temperature flue:Refractory lining；
- Exhaust fan:stainless steel:304；
Furnace steel structure: surface coating, three-proof paint,
surface high-temperature paint；
Gas air duct: surface coating anti-corrosion;
Work platform: Q235 Surface coating of round pipes, panels and
structural steel；
- Furnace body steel plate:Q235,δ≥3mm；
- Furnace volume:Q235 H type steel or square tube
- Hearth frame:Q235,Channel welding and I-beam group welding;
- Crossbar of furnace wall:Q235,Square tube / rectangular tube /
channel steel；
Furnace refractory:
Comparison of refractory cotton and refractory brick
Refractory cotton: advantages-good thermal insulation; light
material; low heat absorption and low energy consumption; long
service life; energy saving.
Disadvantages-cost slightly higher than bricks, slightly worse in
aesthetics.
Refractory brick: advantages-good appearance; cost is slightly
lower than cotton.
Disadvantages-fragile and cracking; heat absorption and energy
consumption are slightly larger; heavy material (resulting in the
overall weight of the furnace body).
Refractory cotton:
The total thickness of the refractory body of the furnace body is
≥300mm.
All furnace lining fiber modules are fixed on the skin steel plate,
making it a sturdy whole, ensuring that the furnace body has
overall air tightness, which can shorten the heating time and save
energy by 10-30% compared with the furnace made of refractory brick
Requirements are reduced.
All-fiber manufacturing, construction, and installation methods
are: all-fiber modules, with a thickness of not less than 300mm,
using zirconium-containing fibers, and a bulk density of 100kg /
m3, which can ensure that it will not shrink, powder, or fall off
under long-term use temperatures.
The composition, specifications, and performance indicators of the
refractory materials in each part of the furnace are equal to or
better than the data in the list:
| Aluminum silicate refractory fiber |
| Chemical composition: | Al2O3:52～57%, Na2O+K2O＜0.2%, Al2O3+ SiO2＞99%, Fe2O3＜0.2% |
| Operating temperature: | 1250℃ |
| Bulk Density(kg/m3): | 220615 |
| Line change rate(%): | ＜4%(1300℃×24h) |
| Thermal Conductivity (W/m K): | 400℃:0.09, 1000℃:0.23 |
| Mullite refractory brick |
| Chemical composition: | Al2O3:45～47%,SiO2:51～53% ,Fe2O3＜0.8% |
| Operating temperature: | 1570℃(max1770℃) |
| Bulk density(kg/m3): | 2600615 |
| Linear expansion coefficient: | 3.47×10^-6 (20-1000℃0 |
How are fire protection products tested?
Many fire tests are run by official laboratories for the purpose of
product certification. However, some manufacturers of fire
protection products also maintain their own facilities and run
tests for R & D purposes before going to the expense and exposure
of a test at a third party facility.
