摘要： A steam generator (2) is described in which a combustion chamber has at least one combustion chamber wall formed by a plurality of longitudinal furnace tubes (10) for passage of an evaporatable flow medium, connected together in gas-tight manner by tube webs. As will be familiar different tubes are likely to be subjected to a heat input in use that varies when the combustion chamber is fired. The tube bores of the furnace tubes are larger where subject to higher heat input than where subject to lower heat input. In particular the tube bores of the furnace tubes are generally larger in the middle region of the combustion chamber wall than at the transversely peripheral regions of the combustion chamber wall.

摘要： A device for introducing hot gas into a heating surface pipe of a waste heat boiler includes an outer pipe that is connected to the boiler wall, preferably to the bottom of the pipe. The device also includes an inner pipe or entry pipe that has an admission section that is cylindrical or conically narrows and also has a discharge section that is connected to the heating surface pipe. The inner pipe is connected to the outer pipe via a rounded reversible cap while forming an entry opening for the hot gas. The inner pipe is surrounded by the outer pipe at a distance. The device also includes a coolant guiding pipe, which is placed between the outer pipe and the inner pipe and which extends into the proximity of the reversible cap. The guiding pipe is provided in the form of a force-transmitting component and is connected, in a removable or fixed manner, both to the inner pipe as well as to the outer pipe each time with at least three connecting ribs which are uniformly distributed over the periphery and which are provided for introducing or transferring forces.

摘要： A continuous-flow steam generator includes a combustion chamber of rectangular cross-section and combustion-chamber walls each having essentially vertically disposed evaporator tubes through which a flow medium can flow from the bottom towards the top. The tubes are connected to one another in a gas-tight manner by tube webs. In order to equalize a differing supply of heat into the evaporator tubes, a heat-absorbing surface formed from an individual evaporator tube and from the tube web assigned to that tube is smaller in the case of evaporator tubes in a middle region of the combustion-chamber wall than at a corner of the combustion chamber.

摘要： A once-through steam generator has a vertical flue formed of tubes which are oriented vertically and which are connected in parallel for guiding a flow of flow medium therethrough. The tubes have a surface structure on an inner wall surface which causes flow turbulence and eddy currents in the flow medium. The surface structure includes first and second, mutually superimposed, contrary ribbings. The first ribbing encloses an acute angle with the tube axis, and the second ribbing extends parallel to the tube axis. The first ribbing forms an onflow flank angle with the tube wall which is flatter than a flow-off flank angle. Elevations of the ribbings rise at least 0.7 mm above the tube wall surface. A mass flow density of the medium in the tubes is adjusted as a function of the inner tube diameter, by maintaining the mass flow density below a predetermined limit curve.
