Bomb Calorimeter


Calorific Value

IKA C200

It allows to measure the higher heating value (HHV) of solid and liquid samples. The sample is completely combusted in an oxygen rich atmosphere in a closed vessel immersed in a well known quantity of water. The energy released by the sample combustion is derived measuring the temperature variation of the water, applying an isoperibol method.

This instrument is installed at the Bioenergy & Biofuels LAB and has been funded by the Autonomous Province of Bolzano in the frame of the development of the NOI Techpark.

Principle of measurament
In an isoperibol calorimeter the temperature in the outer vessel (Tov), is kept constant throughout the experiment. This does not allow a “perfect isolation”. In order to take into account the occurring small temperature exchanges, a correction factor (Regnault-Pfaundler = ξ) is calculated after the experiment.
