Underground coal gasification furnace and underground coal gasification method |
| abstract |
An underground coal gasification furnace comprises an ignition system and a gas injection system. The ignition system is provided with a first vertical drilling well and a first horizontal directional drilling well in communication with the first vertical drilling well. The gas injection system is provided with a second drilling well introduced into a coal seam. At least one second horizontal directional drilling wells of a horizontal section in the coal seam serves as the second drilling well. Also provided is an underground coal gasification method. The method comprises: enabling a flaming fire region of a first horizontal directional drilling well to withdraw in a second horizontal directional drilling well until withdraw to near a coal feeding point. The underground coal gasification furnace eliminates the defects of low cut-through speed and unstable structure in a gasification production stage in the prior art. |
