operated at pressures below 150 psi. Dryers have to be incorporated when fuel 

 moisture content is above 50 percent (Junge 1975a; Corder 1973). 



A new variation of a fuel cell furnace is the wet cell burner (Anonymous 

 1978). This unit employs a cyclonic-type furnace for the upper, secondary 

 combustion chamber (fig. 26-9). Hogged fuel with a moisture content up to 65 

 percent is metered by a hydraulic ram at a rate controlled by Btu demand. The

hydraulic ram then forces the fuel up through a large-diameter cylinder under the 

 base of the burner, depositing the fuel through an opening in pinhole grates that 

 form the floor of the lower chamber. The fuel forms a slightly conical pile over
