Pre-heater for air
A pre-heater is described for air comprising a housing having an elongated air inlet section and an air outlet section, heating means disposed within the inlet section heating air passing therethrough. The heating means consists of a coil disposed in a serpentine fashion within the inlet in fluid communication with a source of heated fluid, an array of baffle plates arranged in a substantial linear plane and disposed in the inlet section and secured to the coil throughout the length thereof and extending throughout the major portion of the inlet and extracting heat from the fluid passing therethrough. The inlet section defines a stepped profile throughout its length causing air to flow through the baffle plates in an undulating manner from the inlet section to the outlet section having heat and ultra-violet emitting tubes disposed therein, and power generating means connected to the tubes to energize the same the cause the heated air to be further dispersed.
