Figure 26-20. — Photograph of the prototype of the Jasper-Koch burner. 



In all suspension burners, small particles are needed. Tests on the Jasper- 

 Koch prototype have shown that the burner runs well with particles sized 

 through the screen (!/2-inch apertures) of a hammermill hog. Heat of combustion 

 of the fuel was 8,500 Btu per ovendry pound. Ash content contents ranged from 

 1 to 4 percent of dry weight, and moisture content as admitted to the infeed screw 

 was 53 percent (wet basis).
