The bomb calorimeter (TD-013) is a benchtop unit that’s used to determine the heat of combustion of different fuels in oxygen atmosphere. The benchtop unit also demonstrates a type of constant-volume calorimeter.

  • The benchtop bomb calorimeter is mainly used in laboratories to measure the heat of combustion of fuels.
  • The educational unit consists of jacketed acrylic vessel, water flask and the fuel bomb.
  • The jacketed acrylic vessel is purposed for providing the needed insulation to avoid heat loss during the combustion. The vessel is made out of clear material to provide a better observation.
  • The water flask is supplied with a stirrer motor to provide a uniform heat distribution during the combustion of the fuel.
  • The stirrer can be controlled using water circulation knob from the panel.
  • The fuel bomb is made out of stainless-steel material and it consists of a combustion cup, release knob, charging input and two electrode ports that are needed for firing the fuel.
  • The release knob of the calorimeter bomb is used to discharge air out of the bomb.
  • The fuel is fired using fuse wire twisted on both electrodes. Heat of firing for the fuse wire is known per centimeter.
  • The fuse wire must be avoiding the contact with the combustion cup to prevent the occurrence of short circuit.
  • The unit is supplied with Pt1000 heat sensors to measure temperature through the combustion process.
  • The trainer is aided with temperature display to state the peak of temperature to be able to perform the required calculations.
  • The trainer is provided with Power control, O/I button for the trainer as well as emergency button as a safety measure.
  • The trainer bench is provided with handles at both sides for easier lifting.
