沼气输气管经的大小,与沼气燃烧效果好坏有直接的关系。合理的输气管径,不仅燃烧效果好,而且经济。那么怎样选择沼气输气管的管径呢? 根据科学测定和实践经验,输气管的内径大小,主要由沼气池到沼气灯、炉具的距离、沼气量的大小和管道压力损失等因素决定。沼气池到沼气灯、炉具的距离远,沼气量大,管道压力损失大,则管径就要 Biogas transmission pipe size, and the combustion of biogas has a direct relationship between good and bad. Reasonable gas pipe diameter, not only the combustion effect is good, but also economical. So how to choose the biogas pipe diameter? According to scientific measurement and practical experience, the inner diameter of the pipe, mainly from the biogas digester to the biogas lamp, the distance of the furnace, the amount of biogas and pipeline pressure loss and other factors. Biogas digesters to biogas lamps, stoves from the far, large amount of biogas, pipeline pressure loss, the diameter will be
