An arrangement for cooling a synthetic gas, generated in a gasification reactor, by means of a quenching cooler. The cooler is positioned below the outlet from the reactor and comprises a refrigerated inner jacket (5) surrounded by a pressurization jacket (1) and accommodating a water sump (6). There is an intermediate section (3) between the inner jacket and the outlet from the gasification reactor that is shorter in diameter than the inner jacket and longer in diameter than the outlet from the reactor. Spray nozzles (15) extend into the inner jacket. One or more gas-outlet connections (8) extend through the inner jacket in a plane above the sump.

Arrangement for cooling a synthetic gas in a quenching cooler

In a rotary tube cooler for indirect cooling of pulverized to granular material with a revolving drum, the drum shell of the rotary tube cooler is formed of a tube system through which a liquid cooling medium is conducted. The tube system comprises either tubes meandering in longitudinal direction of the rotary tube cooler, or be formed of spiral tubes, or the combination of meandering and spiral tubes. The tubes are welded together. The feed of the cooling medium and the discharge of the heated cooling medium occurs via swivel joints. Connected downstream is a device for utilization of the waste heat of the rotary tube cooler.

Rotary tube cooler construction

A method of controlling the heating effect of high temperature gases such as gases obtained in the partial oxidation of oil asphalt, oil shale or coal and the like which are to be used for the heating of another media such as for superheating steam comprises passing the high temperature gases into a space on the way to the heating of the media and circulating a heat absorbing media such as water into the space in quantities to have a selected heat exchange with the high temperature gases and control the temperature thereof on its way to its use in a heat exchanger or superheater. The apparatus include a vessel which is connected between a superheater and a steam producing gas cooler which has an inlet for the high temperature gases which are circulated through the vessel through tubes on its way to the superheater which is disposed over the vessel and advantageously connected to it. The temperature of the high temperature gases which are circulated through the vessel is controlled by the selected admission of an additional heat absorption media such as water into the vessel which may be carried out to the point where the water encompasses the tubes and provides a cooling effect thereon.

Method and apparatus for controlling the heating effect of high

An upright apparatus for cooling high pressure gases with a high dust component includes a radiation/convection cooler with longitudinally extending heat exchanger elements and a convection cooler follows the radiation/convection cooler on the gas side. As distinguished from known devices for the cooling of high pressure gases, the apparatus provides a largely uniform distribution of the gas at the cooling elements and hence a uniform thermal load of the individual elements in the radiation/convection cooler. A uniform cleaning of these cooling elements and easy removal of the dust from the cooling surfaces of these cooling elements is made possible, in order thereby to ensure a good heat transfer. The radiation/convection cooler heat exchanger elements are combined in finned tube walls forming lanes between them, which walls extend from one inner wall section to the opposite inner wall section.
