Patent ID: 8356933

Claim:
Calorimeter ( 1 ) comprising a pressure-yielding decomposition vessel ( 3 ) that contains a combustion chamber ( 2 ) and in which a holder device ( 4 ) for a sample and an ignition device ( 5 ) are located, at least one supply line ( 6 ) is provided for oxygen, a fluid or water jacket ( 7 ) surrounds the decomposition vessel ( 3 ), at least one temperature measurement sensor ( 8 ) projects into the fluid or water jacket ( 7 ), and an outer vessel ( 9 ) encompasses the fluid or water jacket ( 7 ), the outer vessel ( 9 ) is constructed as a pressure vessel and receives pressure produced on its walls due to combustion in the pressure-yielding decomposition vessel ( 3 ) via the fluid or water jacket ( 7 ), and, for equalizing movements due to heat and pressure differences, the walls ( 10 ) of the decomposition vessel ( 3 ) are connected to its base ( 14 ) via a tight, pressure-yielding sliding fit ( 15 ), or a membrane, a bellows, or a moving piston is arranged on the decomposition vessel ( 3 ).
