Process and apparatus for demineralizing water include a fibrous microporous body having interfiber spaces in communication with one another and a porosity at least equal to 50%, water supply elements for supplying water to be demineralized through the fibrous microporous body, a heating device adapted to heat the fibrous microporous body to a temperature of at least 60.degree. C., and elements adapted to collect the demineralized water.

Process and apparatus for demineralizing water

A method and apparatus are disclosed for detecting the presence of steam in a volume of air at a predetermined temperature. The apparatus includes a temperature sensor having two respective temperature build-up times representing an under steam temperature build-up time and an under air temperature build-up time. The method for detecting the presence of steam comprises the steps of placing the temperature sensor in the presence of the volume air, such that the sensor can reach a predetermined set point temperature that is lower than the predetermined temperature, taking a temperature measurement with the sensor, and determining if the measured temperature reaches the set point temperature in order to indicate whether the sensor is in the presence of steam.
