Abstract
The invention concerns the internal structure of a high temperature furnace. That structure includes a dome made of refractory bricks that are capable of withstanding the high temperature within a coal gasification generator. The structure also includes a supporting brick wall under the dome. And, it includes an inner wall made of refractory bricks. The latter is inside of the supporting wall. The inner wall shields the supporting wall from the highest temperature while it is free to expand without being subject to any compressive load from the dome.
