Abstract: PROBLEM TO BE SOLVED: To reduce equipment cost, and avoid a defect of a distributing valve by already obviating the distributing valve in an exhaust gas conduit. SOLUTION: In a power station plant, exhaust gas of gas turbo device groups 40, 41 and 46 is supplied through a supply water conduit 15, and heats water guided through an exhaust heat steam generator 8 by a counterflow. Generated steam is supplied to a steam turbine 1 as a steam utilizing device through a steam conduit 6. Water supplied through the supply water conduit 15 is guided through the exhaust heat steam generator 8 by passing through it once. The exhaust gas of the gas turbo device groups is guided through the exhaust heat steam generator 8 at all operation times. When the steam turbine 1 is cut off, the steam generated in the exhaust heat steam generator 8 is introduced into the gas turbo device groups through a jet steam conduit 23.

Abstract: PROBLEM TO BE SOLVED: To enable an existing device to be used with no trouble by greatly decreasing a dust content of exhaust gases in the device for reducing the exhaust gases of a steam generator. SOLUTION: A front wall 7 and a rear wall 8 of a steam generator are provided on a gas deflection part from a vertical gas pass 4 having downward flow to a vertical gas pass 5 having upward flow so that a dust content is decreased before exhaust gases 18 enter into a convection radiation part 3 of the steam generator. An outer wall 12 has a known gastight tube-web-tube construction, and an inner wall 14 consists of tubes arranged in such a way that once-through flow can occur in each of intermediate spaces between the tubes, wherein a flow-stabilized zone 17 is defined by the outer wall 12 and the inner wall 14, and the inner wall 14 and the outer wall 12 are cooled by cooling media flowing once-through the tubes.
