Abstract:
    A method and apparatus for cooling a hot product gas containing sticky particles which lose their stickiness upon cooling. Hot product gas from a reactor is passed along at least one cooling section consisting of a quench wall provided with a porous wall region, an inlet and an outlet for coolant and a flexible means adjacent to the inner side of the quench wall and its rims being sealingly connected therewith. A coolant is supplied through the inlet and the porous wall region into the space formed by the quench wall and the flexible means. The flexible means is moisturized with the coolant, and the coolant is vaporized thus bulging the flexible means. The vaporized coolant is discharged through the outlet so that the flexible means collapses to its start position and these steps are repeated.
