Figure 28-24. — (Top) Plant layout for annual production of 1,660,000 molded-flake 

 pallets, three-shift basis. Each of the 92- by 112-inch hot presses has two openings. 

 Minimum press cycle for 0.5-inch-thick pallets is 4.5 minutes. (Bottom) Materials 

 balance, ovendry-weight basis, for manufacture of molded-flake pallets. (Drawings 

 after Haataja 1981.)

GAS PRODUCTION WITH A HERRESHOFF 



CARBONIZER^^ 



The Nichols Herreshoff carbonizer (see figs. 26-32 and 26-33 with related 

 discussion) produces charcoal and a combustible low-Btu gas on a continuous 

 basis from bark, wood chips, scrap wood, or agricultural waste. The process 

 normally requires a biomass feed rate of at least 100 tons/day, dry- weight basis.
