Abstract
An apparatus and process for heating a regeneration stream in a thermal regenerative desiccant system having a process stream and a regeneration stream in which a desiccant component rotates through both the process and regeneration streams. The regeneration stream providing the heat required for regeneration of the desiccant is separately heated by each of a plurality of adjacent regeneration stream segments being independently heated. When desired to reduce the total heat provided the regeneration stream, the heat is first reduced only in a first of the regeneration segments contacting the desiccant component as it rotates from the process stream to the regeneration stream. The heat supplied to the first segment is further reduced until it is completely discontinued. Then when still less heat is required for regeneration, heat is reduced to a second adjacent regeneration stream radial segment until it is completely discontinued. Heat reduction may be continued sequentially across adjacent radial segments to meet the heat requirements for regeneration.
