Bomb Calorimeter for measuring the heat of combustion
or calorific value of a material ISO 1716
- A bomb calorimeter, also known as a constant - volume calorimeter, is an instrument used to measure the heat of combustion of a sample. It is a crucial tool in thermochemistry and is widely used in fields such as fuel research, food science, and biochemical studies. By accurately determining the heat released during combustion, it helps in evaluating the calorific value of fuels, the energy content of foods, and the energy changes in chemical reactions.
The working principle is based on the law of conservation of energy. When we put a sample to be tested into a calorimeter and let it undergo combustion or other chemical reactions, there will be a release or absorption of heat during this process. A calorimeter can capture and measure the changes in heat.
If it is used to measure combustion heat, it is like measuring how much heat can be released by burning a piece of fuel. Put the fuel in a special sealed container (usually an oxygen bomb), and then fill it with enough oxygen to ensure that the fuel can burn completely. The heat generated by fuel combustion will be transferred to the surrounding water or other media. By accurately measuring the temperature rise of these media, combined with information such as the mass and specific heat capacity of the media, the heat released by fuel combustion can be calculated.
1. The combustion process is described and analysed based on the experimental results in the context of building fire safety. The bomb calorimeter is the most common device for measuring the heat of combustion or calorific value of a material. Reaction to fire tests for products. Determination of the gross heat of combustion (calorific value).
2. We supply heat of combustion of materials important parameters to characterize the fire risk is calculated building materials release heat and fire load necessary basic data. The tester is one of the devices must be the latest version of the national standard GB8624-2012 construction materials combustion performance classification test.
3. The heat of combustion test device according to GB14402 standard requirements of the development. Determination of heat of combustion of building materials at a constant heat capacity of oxygen bomb calorimeter.
