Abstract: The gas cooler arrangement includes a first pressure vessel in which heat is yielded by radiation and a following convection gas cooler. The pressure vessel of the convection gas cooler includes a faller flue and at least one riser flue for cooling the gas. The flues comprise heat-removing tubes which are parts of a steam generator. The bottom of the pressure vessel contains an ash collection chamber which is connected to the ends of the flues and which can be emptied via a suitable closure element.

Abstract: The hot gas cooler comprises a vertical cylindrical pressure vessel and, disposed axially thereof, an insert which is closed over its periphery and embodied by sealingly welded-together tubes. The tubes are part of the heated pressure system of a vapor generator. The chamber bounded by the insert communicates at the top, by way of a gas supply passage extending through the pressure vessel with a reaction chamber and at the bottom, by way of a discharge passage, with a slag removal facility. Extending around the insert is a jacket embodied by sealingly welded-together tubes, so that an annular chamber closed off from the casing of the pressure vessel extends around the insert. The annular chamber communicates at the bottom with the insert chamber. Disposed in the top part of annular chamber is a coolable gas discharge passage which is connected to the jacket and extends through the pressure vessel.

Abstract: The electrodes of the steam generator are each formed as a horizontally extending disk to receive descending water jets from a distribution chamber above the electrode as well as with openings to direct water jets downwardly onto a collecting grid. The current flows from the electrodes through the water jets to evaporate part of the water to steam. Movable interceptors are also mounted in the vessel to intercept the water jets for partial loads. Suitable means are also provided for selectively moving the interceptors into the path of the water jets at partial loads.
