A device for cooling a stream of hot producer gas exiting from a gasification reactor operating at an increased pressure, includes a set of water spraying nozzles directed against the producer gas stream. Water feeding conduits connected to the nozzles pass through a sealing web provided between the pipe wall structure of the reactor and a separate pipe wall structure of a gas outlet connection piece provided above the discharge opening of the reactor. The geometric locations of respective nozzles are on a circle whose diameter is larger than that of the gas discharge opening and is smaller than the inner diameter of the pipe wall structure of the connection piece. EL ENFRIAMIENTO TIENE LUGAR A ESTE FIN POR MEDIO DE TOBERAS (8) IMPULSADAS POR AGUA ORIENTADAS EN LA DIRECCION DE LA CORRIENTE DEL GAS. SE HA PREVISTO QUE LAS TUBERIAS DE ALIMENTACION (7) DE ESTAS TOBERAS SEAN INTRODUCIDAS EN EL INTERIOR DEL SISTEMA DE GASIFICACION A TRAVES DE LAS CONSTRUCCIONES DE PAREDES DE TUBOS (1, 5) DEL REACTOR DE GASIFICACION (2) Y TUBO DE SALIDA DEL GAS (4) QUE PRESENTAN CIRCUITOS DE REFRIGERACION INDEPENDIENTES. A CUYO FIN LAS TOBERAS (8) SE ENCUENTRAN DISPUESTAS EN UN CIRCULO, CUYO DIAMETRO ES MAYOR QUE LA ABERTURA DE SALIDA DEL GAS (3) DE LA CONSTRUCCION DE PARED DE TUBOS (1) DEL REACTOR DE GASIFICACION (2) Y MENOR QUE EL DE LA CONSTRUCCION DE PARED DE TUBOS (5) DEL TUBO DE SALIDA DEL GAS (4).
