SBISpecification parameters:

1The single combustion test equipment includes a trolley, a fixed frame, a gas collection hood, a collector, a J-shaped exhaust pipe, a centrifugal fan, a wind speed control device, a comprehensive measurement section, a gas analysis cabinet, a data acquisition system, etc;
2The small cart can be installed with two mutually perpendicular sample specimens, with a sand box burner at the bottom of the vertical angle, using surface ignition method, and equipped with a flame detection system as a flameout protection device;
3Fixed frame, small cart is pushed into it for testing and supports the gas collection hood. An auxiliary burner is fixed on the frame and equipped with a flame detection system as a flameout protection device;
4Stainless steel gas collection hood, located at the top of the fixed frame, used to collect the gases generated by combustion;
5Stainless steel J-shaped exhaust pipe, insulated circular pipe with an inner diameter of (315 ± 5) mm, insulated with 50mm thick high-temperature resistant mineral wool;
6The smoke exhaust system should be able to continuously extract smoke at a speed of 0.50m3/s-0.65 m3/s and adjust it using frequency conversion;
7Stainless steel centrifugal fan, capable of withstanding temperatures up to 300 degrees Celsius, meeting the high temperature requirements for step calibration;
8Mass flow controller, with a range of 0g/s-2.5g/s and a reading accuracy of not less than 1.5%;
9By adjusting the propane flow rate through a mass flow rate controller, the gas supply to the burner should be automatically controlled. The gas mass flow rates are 647mg/s and 2000mg/s. The gas control system can ensure that the gas supply rate does not change by more than 5mg/s during the test process, and the output heat is 30.7 ± 2kW;
10The smoke sampling system consists of an ash filter, a compressor condenser, a drying column, a sampling pump, and a peristaltic pump to ensure effective collection and clean drying of smoke samples;
11Diaphragm pump, flow rate: 400l/h, can withstand high temperatures and corrosion, used for collecting sample gases;
12The filter head of the smoke and dust filter is composed of solid PTFE, with an internal filter material of 0.5um;
13Compressor type condenser, cooling capacity of 320KJ/h, dew point stability of 0.1 degrees, dew point static change of 0.1K, protection level IP20;
14Imported rotor flowmeter with a range of 0-5L/min, adjusting the inlet flow rate of the analyzer;
15Paramagnetic oxygen analyzer, with a range of 0-25%, measures the oxygen concentration in gas, with a concentration range of 0-25% and T90<12 seconds;
16Non dispersive infrared CO2 analyzer: CO2:0～10％；
17The pipeline with a comprehensive measurement area length of 2155mm is equipped with pressure probes, three thermocouples, gas sampling probes, and white light systems;
18A bidirectional probe is connected to an inlet pressure sensor with a range of at least (0-100) Pa and an accuracy of ± 2Pa. The response time of 90% output of pressure sensors is mostly 1 second;
19Gas sampling probe, connected to gas regulating device and O2, CO2 inlet gas analyzer;
20The light attenuation system is of incandescent type and is installed on the side pipe of the smoke exhaust pipe using flexible joints;
21The lamp is an incandescent lamp and is used at a color temperature of (2900 ± 100) K. The power supply is stable direct current, and the fluctuation range of current is within ± 0.5% (including temperature, short-term and long-term stability);
22Lens system, used to gather light into a parallel beam with a diameter of at least 20mm. The light-emitting hole of the photoelectric tube should be located at the focal point of the lens in front of it, and its diameter (d) should be determined according to the focal length (f) of the lens so that d/f is less than 0.04;
23The detector and silicon photodiode probe have a linear stability of 0.1% and a measurement range of 10 digits in the photoelectric detection chamber. The spectral distribution response of the silicon photodiode matches the CIE (illumination curve), and the standard function V (γ) can achieve an accuracy of at least ± 5%;
24The 90% response time of the light attenuation system should not exceed 3 seconds;
25Introducing air into the side tube to maintain the cleanliness of the optical components that meet the requirements of light attenuation drift can be achieved by using compressed air;26Size:Cart size: 1500mm (W) X 1620mm (D) X 2200mm (H)Frame size: 1700mm (W) X 2500mm (D) X 2200mm (H)27Weight:650KG
