1选择粗细合适的沼气输气导管输气导管内径的大小,要根据池子的容积、用气距离和用途来决定。如沼气池容积大,用气量大,用气距离较远,则输气导管的内径应当大一些。一般农户使用的沼气池输气导管的内径以0.8～1.0厘米为宜。管径小于0.8厘米,沿程阻力较大,当压力小于灶具(灯具)的额定压力时燃烧效果就差。不允许使用再生塑料管
1 Select the appropriate thickness of the biogas feed pipe diameter of the gas pipeline, according to the size of the pool, gas distance and use to decide. If biogas digester volume, gas consumption, gas distance, gas pipeline diameter should be larger. Biogas digesters used by average farmer gas pipe diameter of 0.8 to 1.0 cm is appropriate. Diameter of less than 0.8 cm, the resistance along the way larger, when the pressure is less than the rated pressure cooker (lamp) the combustion effect is poor. Recycled plastic pipe is not allowed
