ABSTRACT:
Hot fuel gas from coal gasification passes countercurrent to cycling heat transfer solids in a tower to lose heat to the solids. The thus cooled fuel gas has sulfur removed and then passes countercurrent in the tower to the now hot solids to cool the solids and reheat the fuel gas. The heated and purified fuel gas is exited from the tower for consumption as in a power plant. The solids are free to flow by gravity but are constricted in the vicinity of the midsection of the tower. This constriction in conjunction with control of gas pressure by monitoring of hot inlet gas pressure and hot but purified fuel gas outlet pressure prevents one or the other of the gases from bypassing the path desired for it.
