Abstract
Abstract Dispersing means for improving the mixture of water droplets emanating from atomizer-type humidifiers with the hot air conducted from a heating plant is disclosed. The dispersing means is of a configuration e.g. is a constricted tube, so as to cause turbulence in the hot air stream flowing through the dispersing means and it is into this turbulence that the atomized water droplets are projected. The resulting improved mixture deters ''''liming'''' and dripping in the system.
