ABSTRACT:
A fuel dryer system for waste fuel boilers, such as for example those in the sugar cane processing industry where bagasse is used as a primary fuel, in which the dryer comprises an assembled, enclosed, vertical dryer structure of basically cylindrical shape through which hot drying gases flow with a conical materials collecting hopper and bottom discharge, having alternating conical-shaped rotating and fixed materials trays over which the materials (e.g. bagasse) to be dried move in a net direction from top to bottom (note Figure 1). Adjustable wipers are provided with the conical materials trays, with access portholes at each tray level. In the sugar cane boiler system the stack gases from the boiler are used for the hot drying gases (note Figure 5).
