石炭地下ガス化における炭層内燃焼帯の移動速度と日本における石炭地下ガス化方式の提案

抄録

In this paper the auther analysed the relation between rate of combustion zone movement and distance from the center of borehole.
The increase of distance from the center of borehole brings to the decrease of rate of combustion zone movement very rapidly, that is to say, the combustible zone around borehole is restricted. The author examined the suitable methods-increase of blast quantity and blast of oxygen gas-to enlarge the combustion zone in gasification.
In accordance with results obtained, the author proposed one nuderground gasification system considered to be suitable in Japan.
