ISO834-1 Multifunctional Horizontal Combustion Test Equipment ,
Combustion Test Furnace
Application
Suitable for load-bearing and non-load-bearing members such as
walls, beams, columns, slabs, ceilings and roofs. Other structures,
fittings or structures can be used as reference.

Technical parameters
Refractory test furnace: It is a horizontal test furnace with a
size of 6M (length) x 6M (width) x 3M (high) (can be customized),
and the interior is made of high temperature resistant insulation
material.
Loading device: mechanical loading to move the bridge crane inside
the building. Ability to simulate uniform loading, centralized
loading, axial loading, or eccentric loading.
Support frame: connected to the wedge bracket on the frame by four
rollers.
Thermocouples: thermocouples in the furnace, backfire
thermocouples, moving thermocouples, internal thermocouples,
ambient temperature thermocouples are distributed in various areas.
In-furnace pressure measuring probe: T-shaped measuring probe with
measuring accuracy ± 2Pa
Test piece gap measurement probe: ±0.1mm diameter 6mm diameter
±0.2mm diameter 25mm
Combustion system: gas distribution system (within 10 meters), fire
nozzle (not less than 20) and regulating valve
Combustion gas source: natural gas (user-owned)
Gas flow rate: 0~100L/min Measurement accuracy 2.5
Air flow: 0~50m3/min Measurement accuracy ≤±0.5m3/min
Gas tank capacity: ≥50kg×6
Furnace temperature control system: 10 points maximum sampling
point
Ventilation system and control damper, etc.
Radiation heat measurement of the back surface of the test piece:
0~10W/cm2
The furnace temperature and pressure control is connected to the
control system via the computer's RS485. The DC output voltage of
the combustion test sensors such as thermocouples and pressure
sensors is converted to digital form and can then be passed to the
computer system for display and storage.
