Aiming at the problems of fused ignition of oxygen bomb calorimeter

such as complicated operation caused by manual winding of ignition wire

inconsistency between actual ignition heat and experimental set-up ignition heat and occasional failure of ignition

the internal structure of oxygen bomb and ignition principle of ignition wire are analyzed.Combining with existing laser technology

the source of laser is generated. After the parallel light is focused by the focusing mirror

it is irradiated on the surface of the coal sample in the crucible to ignite the coal sample to ensure that the ignition success rate meets the requirements. Then the main engine of the oxygen bomb calorimeter and the oxygen bomb are reformed. The original fused ignition mode in the oxygen bomb is made by using two laser ignition schemes

i.e. the laser head is built in and the position of the oxygen bomb. It has been proved by extensive experiments that there is no significant difference between the fused ignition mode and the two laser ignition modes. The laser ignition mode can be replaced each other. The laser ignition mode can be repeatedly ignited

which reduces the labor intensity. The automation level of equipment is provided

and the utilization rate of equipment is also improved.
