Can someone explain how bomb calorimeter works, and would we need to know technically how it works?

Bomb calorimeter is basically a system where a reaction takes place at constant volume. Since volume is constant, then change in internal energy (deltaU) would be equal to just q since deltaV is zero.

I attached a picture which I thought might help. In terms of function, the ignition wires start the combustion, and since there is no change in volume all of the energy is released as heat. The heat raises the temperature of the surrounding water and the temperature of the water is measured using the thermometer.
