Composting under controlled conditions

摘要: Abstract Three cylindrical reactors, each with a working capacity of approximately 200 litres, were used to investigate composting. The process was optimised and conditions controlled so that composting on laboratory‐scale thermally resembled occurring in the core large open heaps. A baseline flow humidified air aerated reactors five‐minute bursts. operated as closed systems facilities analyse composition off‐gas for ammonia, oxygen carbon dioxide. Temperature monitor progress process. Heat loss from reactor surface compensated an external heat source. basic model radial conductive losses showed 53 wattsper square‐metre would be maximum flux needed keep temperature difference across within degree when running at 60°C. heating cable used, which could supply 150 square‐metre, reduced in...
