Brief introduction: In the constant heat capacity of oxygen bomb calorimeter, test of building materials combustion heat value. Including combustion gross calorific value and net calorific value. In line with the GB/T14402-2007 "building materials and products of combustion performance - determination of combustion heat value and ISO1716:2002 test standard. Technical parameters: Calorimetric bomb: 1. Capacity: (300 +) 50 mL 2. Quality: 3.25 kg 3. The shell thickness is more than 1/10 of the shell inside diameter 4. The lid can let put the crucible and the electronic ignition system, the lid and all of the sealing device 21 mpa can withstand the internal pressure 5. The inner wall of the shell adopts USU304 # stainless steel can withstand the erosion of sample combustion products, also can resist acid from the burning of the pitting corrosion and corrosion. Calorimetric apparatus: Outer barrel for double container, 1 calorimeter with insulation cover, filling between the internal and external wall thermal insulation material, outer tube filled with water, the outer wall wall around 10 mm gap with the calorimeter, contact area of the smallest three points to support the barrel. Inner barrel: 2 calorimeter for polishing metal containers, used to hold oxygen bomb, can make the oxygen bomb completely into the water. Automatic filling equipment, test if there is a lack of water, equipment automatically added, volume: 2200 ml. 3 stirrer: by constant speed motor drive, heat transfer, avoid calorimeter with outer barrel cover and the outer barrel stirring shaft touching part quality, separated by using thermal insulation gasket, choose the same performance of magnetic stirring device; The stirring power: 3 w; The stirring speed 375 r/min. Temperature measuring device: resolution: 0.0001 ℃, the OMEGA precision PT100 sensors in the United States. Temperature measurement of platinum resistance temperature derivative 1/1000; Crucible: stainless steel, distribution of two. Timer: record test time, accurate to S, the accuracy of 0.1 S/h Power supply: AC 185 ~ 245 v. Pressure gauge and needle valve: installed in the oxygen supply, back to the way show oxygen bomb, the pressure of oxygen filling when accurate to 0.1 Mpa, oxygen bomb oxygen filling 0 ~ 3.5 Mpa pressure without leakage. Burning gross calorific value: > 10 kj/kg The combustion heat value repeatability error: 0.2% or less Temperature measurement range: 0 ~ 50 ℃.
