Summary
"Wood has been used as a source of heat for centuries, and recent advances such as gasification technologies, automated fuel handling systems, emissions control devices, and the use of hydronic heating systems have led to cleaner burning and higher efficiencies. All of these advances are changing the way wood energy users interact with forest environments--this is especially true in rural areas. School-size systems often have outputs of between about 1 and 5 million British thermal units (MMBTUs) per hour ... In Alaska, recent adoption of wood energy has been significant and growing, with close to 25 small-scale industrial systems currently in use ... Although combustion gas composition and operating efficiencies can reveal a great deal about wood energy operating conditions, very few studies have evaluated these parameters at larger than residential scales"--Pages 1-2
