ISO834-1 Fireproof Glass Steel Structure Fireproof Coating Fire Testing Furnace

^{DX8810A Steel Structure Fireproof Coating Test Furnace}

Remark:

It is suitable for determining the fire resistance characteristics of horizontal building components such as walls, beams, columns, floor slabs and suspended ceilings under standard fire conditions.It is suitable for determining the fire resistance characteristics of horizontal building components such as walls, beams, columns, floor slabs and suspended ceilings under standard fire conditions.

Technical parameters:

⑴ Test products:

- building components and accessories

Fuel:

- natural gas or liquefied petroleum gas

Working temperature:

- design limit temperature 1300 ℃, long-term working temperature 1200 ℃,

Increase the temperature according to the set formula.

Appearance temperature rise of the device:- ≤55 ℃

• Temperature measurement: 4 K-type nickel-chromium-nickel-silicon thermocouples (wire diameter 0.75-1.5mm) thermocouples and 10 thermocouples on the back of the sample in the device.
• Pressure measurement: 3 pressure sensors ± 100Pa, micromanometer with an accuracy of ± 2Pa.
• Combustion method: 4 spray guns are installed horizontally on the side (one on the back and two observation holes on the side).
• Spray gun power: 60KW per side;
• Control method: Fully automatic control of temperature and kiln pressure (automatic execution of standard time-temperature curve and automatic execution of kiln pressure curve).
• Test car: equipped with 2 steel test cars (size 1.3 * 1.3M).
• Air supply for spray gun: 7.5KW high-pressure centrifugal fan is used for air supply, and the air pressure is 1.8KPa.
• Temperature control: Adopt high-precision proportional valve and automatic actuator to automatically control the furnace temperature.
• A high-precision pressure sensor + pressure PID controller + Delta frequency converter is used to form a closed-loop control to achieve automatic control of the pressure in the furnace.
• Exhaust gas system: Use a spray tower to cool and remove the high-temperature exhaust gas discharged from the furnace and then discharge it.
• Software design: meet the temperature and pressure requirements of ISO834-1, EN1363-1.
• Total installed power: 10KW
• Total combustion power: side 240KW

Power supply: three boxes and four wires, 380V / 50HZ

Buyer-provided fuel (natural gas or liquefied petroleum gas)

The main steel structure of the device:

- Use H steel + steel plate + square steel welding

Device masonry insulation:

- The thickness of the insulation layer is 300MM, which is made of high-temperature ceramic cotton + high-temperature refractory bricks

Furnace pressure control system:

The flue gas in the device is mechanically discharged by the fan through the bottom of the furnace, and the flue gas is discharged outside after being treated with air and polyester. The exhaust fan is controlled by the frequency converter to ensure that the furnace pressure is controlled within the standard range. A stable furnace pressure is a necessary condition to ensure the execution of the temperature curve. Three pressure measurement points are designed in the furnace, one of which is controlled and two are displayed.

Kiln combustion system:

- Gas safety system (connected from pipeline natural gas or liquefied petroleum gas to kiln gas safety control system)

- Gas spray gun

Gas spray gun temperature control system

- The device adopts four sets of combustion systems on the side, each combustion gun can achieve independent combustion, and can meet the heating requirements.
