FIELD: manufacture of boilers; operation of boiler units. SUBSTANCE: membrane panels of vertical sections of loops are shifted towards side baffle walls forming gas duct between them; side baffle walls of intermediate gas duct are interconnected by means of additional sections of tubes to which two rows of horizontal tubes are connected; these tubes are interconnected by means of vertical sections forming loops; vertical sections of extreme loops are interconnected by means of spacers, thus forming membrane panels rigidly connected with transversal baffle walls. Vertical sections of inner loops may be mounted in planes of vertical tubes of loops and are fastened with them by means of spacers. Additional supports are mounted under vertical sections of connection of membrane panels of inner loops to transversal baffle wall separating furnace and intermediate gas duct. EFFECT: reduced dimensions of boiler; enhanced reliability. 3 cl, 5 dwg |
