Abstract
Heat exchanger for quenching reaction gas comprising—a coolable double-wall tube including an inner tubular wall and an outer tubular wall, wherein said inner tubular wall is configured to convey said reaction gas to be quenched, and wherein a space defined by said inner tubular wall and said outer tubular wall is configured to convey a coolant; —a tubular connection member having a bifurcating longitudinal cross-section comprising an exterior wall section and an interior wall section defining an intermediate space filled with refractory filler material, wherein a converging end of said connection member is arranged to be in connection with an uncoolable reaction gas conveying pipe, wherein said exterior wall section is connected with said outer tubular wall of said coolable double-wall tube, wherein an axial gap is left between said interior wall section and said inner tubular wall of said coolable double-wall tube.
