(57) : A humidification system has a humidification source and a main gases flow path. The main gases flow path has a low pressure region and a high pressure region. In some embodiments, each of the low pressure region and the high pressure re- gion has an aperture. The pressure difference between the apertures promotes a gases flow between the main gases flow path and the humidification source, and results in humidifying the gases in the main gases flow path.
