The foundamental data to design the 180t retort are required.The heat balance of the retort and the distribution of fixed carbon in shale, the function of the intermediate zone and brick arch between the distilling retort and producer, the capacity and heat transfer in the distilling chamber, the distribution of temperature and the height of combusion zone in the producer chamber etc were investigated.
1.The simplified equation derived from Haslam's experiments was explained by the actual operating data very well.
2.The amount of air blast should be reduced and the saturation temperature of the.blast should be rised for the prevention of clinker formation and cracking of oil vapor distilled out.
3.Only one half of residual carbon in the distilled shale was gasified in the producer chamber and this carbon may be the effective source to replace the circlating hot gas from the regenerator.
4.The thermal conductivity of the shale decreascd very much as the drying and disti-llation proceeded.
5.Water gas reactions in the producer chamber were found to follow approximately to the first order reaction kinetically.
