Main technical parameters ( NF P92 IR Thermal detector)

(1) Test chamber: L1243mm made of stainless steel W460mm H1661mm is plate and made of high temperature electrostatic connected to the exhaust baking paint. The 50 mm high there is a smoke exhaust port on the upper part, and the wall of the box body has a protective layer of insulating and non-flammable material of about 30 mm thick. The protective lower part has a fixed opening filtering device to layer is made of 1/8 of vermiculite concrete an exhaust passage with forced suction and regulator, the exhaust, and is equipped with a transparent observation window. It adopts stainless steel tubular air inlet device passage is port of the test chamber and is equipped with a shield indoor pollution sources.

(2)Radiator: Irradiator heat radiation device, rated power is 500W, the radiation surface is a quartz disk with a diameter of 100±5mm. The spiral wound around the and the groove radiating surface and is in the disk is spiral groove has 6 turns. The radiator has a heat flux density of 3 W/cm 2 in a parallel plane of 30 mm from the resistance wire for heating, as uniform as possible.

(3)Sample support frame: A rectangular frame with a high-end open state is made of three angle irons, which is U-shaped. A fixed mark is welded to the angle irons on both sides of the support frame to measure the length of the flame. Sometimes the test requires the use of a sample net, so two clips for the fixed net are welded to both sides of the support. The sample holder and the radiator are mounted on the same bracket. The plane of the sample holder is inclined at 45°, and the low end is 250 mm from the bottom of the test chamber. The radiator is passed through an adjusting device such that the radiant disk surface is parallel to the plane of the sample support frame with a spacing of 30 mm. The center line of the radiant disk is in a plane equidistant from the left and right sides of the sample support frame, and the lower end of the radiant disk is about 40 mm away from the lower end of the sample.

(4)Guard net: The net made of 3mm diameter steel wire is divided into two forms, one for the material with insufficient rigidity and the other for the material with obvious creep during the test. During the test, the net is placed on the sample support frame and the distance between the surface of the sample and the radiating surface of the radiator is guaranteed to meet the specified requirements.

(5) Fire-fighting device:

Lower ignition device: The jet portion of the lower ignition device has a circular arc shape with a radius of 100 mm and an effective length of 180 mm.

Upper igniter: The upper part of the igniter is rectangular, the effective length of the lance is 60mm, the inner diameter of the nozzle is 6mm, and there are small holes with a diameter of 0.6mm, and the whole spacing is 20mm.

(NF P92 IR Thermal Detector)

Gas	Butane or propane gas
Length of the pilot fire	15 mm
Each pilot	Equipped with a valve with an accurate indicator to regulate the flow of gas. The needle valve controls the upper and lower burner flame heights and is equipped with a flame height gauge.
At the rear of the pilot	There are two fixed ignition tubes that can ignite the jet.
Regulating portion of the pilot device	Placed outside the test chamber to adjust the distance between the pilot and the sample during the test.
Temperature measuring device	Five thermocouples (nickel-chromium-nickel-aluminum-magnesium alloy thermocouples are placed in the center of the test chamber exhaust port and four diagonals, and five thermocouples are placed on the horizontal line at the bottom of the tank. The the temperature difference and the input end temperature difference show the airflow value status in real-time.

What is Thermal Radiation?

Thermal radiation is the emission of all matter that has a temperature Thermal radiation reflects absolute zero. Conversion of thermal electromagnetic waves from the greater than energy into electromagnetic energy Thermal energy is the kinetic energy of random movements of atoms and molecules in matter
