The vapour arrising from the evaporation of the water is conveyed by suitable pipes or passages into a brook or river, 5 by which means it is converted into pure water and polluteth not the stream. In some cases it may be found advantageous as well as economical on withdrawing the semi-solid matter from the boilers to further dry the same by an arrangement of drying kilns, heated or partially heated by io any free or additional waste heat arrising from the calcination of the lime, that the said matter may be the more conveniently removed and the lime may be used as a deodorizer.
