Heat release calorimetry test equipment HRC

batterymaterial

The Heat Release Calorimetry, provides a means of determining the burning behavior of the material by measuring specific test responses when the test specimen is subjected to a specified flame ignition. The test will be conducted in an opening exhaust hood, size in 6000mm by 6000mm, with a well ventilated conditions. The measurement to be made include the rate of heat and smoke release, total heat released, smoke released etc. Exhaust Hood and Duct • A stainless steel made hood is installed above the floor, size is 6 meters by 6 meters. • The hood is used to collect the combustion gas and transfer to the exhaust pipe by the plenum chamber on the top. • The side skirt is installed underneath the edge of hood to improve smoke capture, made of glass fibre cloth, resistant to temperatures up to 1100°C. • The exhaust pipe is 1200mm in diameter and 8 times diameter in length. • The hood and duct are connected to the exhaust system that capacity not less than 60,000 m3/h. Instrumental Section • The instrumental section is installed in the end of exhaust duct, equipped with thermocouples, differential pressure transducer, sampling probe, and white light system. • The flow sensors used in the exhaust duct is a bi-directional probe, the probes are made of 316 stainless steel. • The pressure transducer with a range of at least (0-200) Pa and an accuracy of ±2 Pa. Response time of 90% of the output of the pressure transducer is not more than 1s. • Equips 3 OMEGA K type thermocouples for temperature measurement, 24 AWG wire gage, measurement range up to 1000 degrees, accuracy of ± 0.75%.
