1104 Oxygen Combustion Vessel Preface Scope These instructions cover the procedures to be followed when using a Parr 1104 Oxygen Combustion Vessel (or bomb) to determine calorific values of solid or liquid combustible material in a Parr calorimeter. The user should study these instructions carefully in order to obtain a complete understanding of the capabilities and limitations of an 1104 Oxygen Combustion Vessel, and to be well aware of the precautions to be observed in its operation.
1104 Oxygen Combustion Vessel Sample Preparation (continued) Operation It is not advisable to test true explosives in the presence of oxygen. Some of the end products of the explosion will be combustible in high-pressure oxygen, for example, mixed oxides of nitrogen and carbon monoxide. With high-pressure oxygen available, these will burn to carbon dioxide and release an undeterminable amount of heat that did not come from the initial reaction of interest.
1104 Oxygen Combustion Vessel Preparing the Fuse When the Combustion Cage is Used Set the bomb head on the support stand (P/N A38A) and attach one end of a 10 cm length of fuse wire to the hook on the straight electrode. Run the wire through the slot in the cage, then up through one of the holes in the top plate. Anchor the free end under the head of one of the nearby screws.
1104 Oxygen Combustion Vessel Preparing the Fuse When the Combustion Cage is Not Used (Continued) Set the bomb head on the support stand (P/N A38A) and attach one end of a 10 cm length of fuse wire between the two electrodes. Fasten one end of the wire to the loop electrode (steps a thru d) then attach the other end to the straight electrode (steps e thru h). Pull the loop downward to tighten the connections then bend the wire upward (step i).
1104 Oxygen Combustion Vessel threaded on instead of pushed on to the inlet valve. The correct assembly to use when filling the 1104 from a calorimeter is P/N A19A15. Close the outlet valve on the bomb head. Thread the end of the fill connection on to the inlet valve of the 1104. Press “O2 Fill” on the calorimeter to fill the vessel. Filling the Bomb Manually To fill the vessel directly the 1823 Oxygen Fill Connection must be used. Close the outlet valve on the bomb head.
