FIELD: power engineering. SUBSTANCE: secured to upper drum-separator 1 of boiler by means of banks 2 are two lower drums 3. Banks 2 are located symmetrically relative to longitudinal axis of boiler and are provided with inlet and outlet ports 4 and 5. Arranged in banks 2 between rows of tubes directed towards boiler axis are spacers connected with tubes by means of gastight joints forming walls of bypass passage with triangular cross section. Cooled gate 6 is mounted in outlet section of passage for rotation about its axis. Gas dispensing chamber 10 is provided with oval inlet opening 4. Tube screens are located in outlet section of chamber 10; position of tubes in screen provides for deflection of gas flow. Boiler is provided with gates each of which is located at bank outlet. Gas bypass ports are provided in walls of passage. EFFECT: enhanced reliability. 6 cl, 8 dwg
