Burning calorific value test equipment for building materials and products

Burning calorific value test equipment for building materials and products is a device used to measure the heat of combustion of a substance in a sealed container (called a bomb) filled with pure oxygen under high pressure. The sample is burned in the presence of oxygen, and the heat released is absorbed by water, which surrounds the bomb. The temperature rise of the water is then measured and used to calculate the heat of combustion of the substance.

Comply with the test standards of ISO 1716-2002 "Reaction to fire test for building materials and products—Determination of the heat of combustion".

3. Main parameters:

3.1 Total gross heat of combustion: 0.01MJ/kg ~30MJ/kg

3.3 Temperature measurement range: 0～50℃.

3.4 Temperature resolution: 0.0001℃ with using PT100 sensor

3.5 Oxygen bomb volume is 300ml. Quality is 3.2kg.

3.6 Inner cylinder volume: 2200ml

3.7 The oxygen bomb oxygenation pressure is 0～3.5Mpa without air leakage.

3.8 Oxygen bomb pressure resistance: ≥21Mpa water pressure.

3.9 Stirring power: 3W.

3.10 The stirring speed of the inner cylinder: 375r/min.

3.11 Power supply: AC 185~245V.

3.12 Ignition circuit: The voltage is 12V, the adjustable current is 100mA, and the ignition wire is an iron wire with a diameter of 0.1mm.
