Cubed Straw Fuel
"It burns cleaner than wood, coal or oil and it's just as easy to use," says Peter Cullen, representative of New Air Technical Services, Ltd., Leicester, England, about the companys' new straw briquetting machine.
The machine uses incredibly high pressures of up 52 tons per square inch to compress hay into 2-in. dia. mini-logs of varying lengths. The process uses no liquid to bind the straw together. The high pressure of the compactor causes the straw to heat up enough so that it binds itself together, making it 40 times more dense than unpacked straw. The straw is then extruded through a long, 90-ft. cooling tube.
The Naw Air machine can make as much as 1/3 ton of briquettes per hour. Bales of straw are fed to the machine's shredder by an automatic conveyor. A complete straw briquetting turn-key operation sells for about $47,000.
