The utility model provides a membrane wall structure, including a plurality of condenser tube that arrange side by side to and weld the steel sheet between adjacent condenser tube, be equipped with cowl between adjacent condenser tube's inside wall and the steel sheet in the recess that forms, cowl with the steel sheet is tangent or have an interval of predetermineeing. The utility model discloses a set up cowl between condenser tube and steel sheet, when flue gas stream advances membrane wall, the gas -flow resistance has been reduced, and avoid forming the air current swirl in many local dead angle departments, prevent that the smoke and dust adhesion is on the mode wall, especially, the adhesion gathers a large amount of smoke and dust in dead angle department, the cooling effect of water -cooling wall has been improved, furthermore, still can set up the detachable adsorbed layer on condenser tube's inside wall and cowl, can collect the smoke and dust to the adsorbed layer on, and by staff's periodic replacement, simple operation, and popularization is facilitated.
