BAGASSE AS FUEL

which scheme appear again in one (8320 of 1903) granted to the Stirling 

 Boiler Co. This scheme is shown diagrammatically in Fig. 283. Bagasse 

 direct from the mill is delivered to an elevator, which in turn discharges 

 to a scraper carrier, a, running in a direction at right angles to the furnaces. 

 From the mouths of the furnaces, b, shoots, c, communicate with the 



FIG. 282 



carrier, over each shoot being a sliding trap door controlled from below, 

 whereby bagasse may be directed to the shoot, whence it gravitates to the 

 furnace. The actual feeding to the furnace is often effected by a rotating 

 drum, d, on which are placed longitudinal projections, e, shown on an 

 enlarged scale in the right-hand sketch. In this design the door, /, auto- 

 matically closes when the hopper is empty. 



Two lay-outs of furnaces are general. In one they are arranged in two 

 lines between which is located a platform, on to which surplus bagasse may

be discharged through trap doors, and which serves as storage room. Other- 

 wise the carrier may be extended beyond the line of the furnaces, and may 

 discharge any surplus to a shed there located. In this case a return carrier 

 is provided to deliver the surplus back to the main carrier when required. 

 The boilers used in connection with bagasse are not specialized types,
