A heat exchange section ( 1 ) composed of a fuel supply part ( 7 ); core ( 5 ), and steam collecting part ( 9 ). A heat exchange section ( 1 ) composed of the fuel supply part ( 7 ), core ( 5 ) and steam collecting part ( 9 ) is secured to a side wall plate ( 37 ). Three faces of the heat exchange section ( 1 ) except for the side wall plate side, high temperature gas inlet side and outlet side are covered by the housing body ( 43 ). Heat resistant filler ( 45 ), intervenes between the housing body ( 43 ) and the heat exchange section ( 1 ). An upper and lower portions ( 43 b, 43 c) of the housing body ( 43 ) are prevented from deforming due to thermal expansion of the core ( 1 ) by a heat deformation absorbing mechanism ( 47 ) which is formed by bending the joint of the flange ( 43 a) of the housing body ( 43 ) and an upper and lower end portions ( 37 a) of the side wall plate ( 37 ).
