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 Alternative and additional test procedures

Hydrocarbon (HC) fire heating curve

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:

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.
