A catalytic combustion apparatus has a cylindrical housing defining a fluid passage, and a plurality of combustion catalyst bodies arranged face to face along the fluid passage in the cylindrical housing. The catalyst bodies are loosely fired in the cylindrical housing. Each catalyst body defines numerous bores extending along the fluid passage. The cylindrical housing includes holders extending inwardly of the housing for contacting end surfaces of the catalyst bodies to prevent movement thereof along the fluid passage.

A catalytic combustion apparatus comprising: a cylindrical housing defining a fluid passage; a plurality of combustion honeycomb catalyst bodies transversely disposed in said cylindrical housing and defining numerous bores extending along said fluid passage, wherein said combustion catalyst bodies are loosely fitted in said cylindrical housing to allow for thermal expansion and contraction of said combustion catalyst bodies; and holders provided in said cylindrical housing for contacting end faces of said combustion catalyst bodies extending transversely of said fluid passage to prevent axial movement of said combustion catalyst bodies along said fluid passage, said holders including: a grid provided at an outlet portion of said cylindrical housing for supporting substantially an entire area of at least one adjacent of said combustion catalyst bodies; a plurality of engaging elements fixed within said cylindrical housing in between each successive pair of combustion catalyst bodies and extending from an outer member of said cylindrical housing through an inner face of said cylindrical housing, leading ends of said engaging elements projecting into said cylindrical housing, said engaging elements contacting end surfaces of said combustion catalyst bodies thereby to hold said combustion catalyst bodies against axial movement thereof along said fluid passage; and means for fixedly positioning said engaging elements, said means being provided to said cylindrical housing so as to cause the leading ends of said engaging elements to project into said cylindrical housing by a predetermined projecting length.
