Initial fabrication and experimentation of an up-flow type pyrolysis reactor started tow years ago. Full-scale improvements were also made on the equipment. Rice husks and bark pellets were used as test materials. Since this particular furnace is small (30cm I. D.), bridging inside the furnace was not possible. During experiment, the amount of combustion air was specified and, the furnaces exhaust gas temperature was automatically controlled at a temperature higher than the water boiling point. The amount of material supply, mass of produced gas and tar, inside and outside temperatures of the furnace, were measured. The conditions for supplying steam for water gas reaction, gas and tar separation, as well as the driving of the engine using produced gas were modified. The following are the results :(1) All the moisture from the material and those generated during pyrolysis can be fully exhausted from the furnace by controlling the exhaust gas temperature. (2) Full-scale improvement of the furnace resulted in the formation inside the furnace of a thin drying layer and a thick reduction layer thus achieving an effective reduction reaction, thereby increasing the heat valve of the produced gas. (3)Tar oil consists of heavy tar, liquid acid, and light tar. Heavy tar can be recycled by mixing it in the raw material, liquid acid could be used as agricultural chemical, and light tar could be used as fuel. (4) It was possible to burn the top portion of the tar oil which was stored for a long period of time even if it contained 72% moisture. The heat value was comparable to that of a petroleum. (5) Maintaining the reduction layer thickness controls the water gas reaction thus controlling the produced gas heat value.Consequently, the optimum operation applicable to the local conditions of the region can be realized by the above results.

上流式热解反应器的初步制造和试验始于两年前。对设备也进行了全面改进。稻壳和树皮颗粒被用作测试材料。由于这个特殊的炉是小（30厘米I。D.），在炉内桥接是不可能的。在实验过程中，燃烧空气的量是指定的，炉废气温度自动控制在高于水沸点的温度。测定了原料供应量、煤气和焦油的生成量、炉内外温度。对水煤气反应、煤气和焦油分离以及用采出煤气驱动发动机的供汽条件进行了改进。结果表明：（1）通过控制排烟温度，可以将物料中的水分和热解过程中产生的水分全部排出炉外。(2)炉的全面改进导致在炉内形成薄的干燥层和厚的还原层，从而实现有效的还原反应，从而提高了所产生的气体的热值。（3）焦油由重焦油、液体酸和轻焦油组成。重质焦油可通过掺入原料中回收利用，液体酸可用作农药，轻质焦油可用作燃料。(4)即使焦油含有72%的水分，也可以燃烧储存了很长一段时间的焦油的顶部。热值相当于石油。(5)通过保持还原层的厚度，可以控制水煤气反应，从而控制煤气热值，根据上述结果，可以实现适合当地条件的最佳操作。
