Abstract
Exhaust gas purifier of the manifold reactor type is adapted to prevent the dispersion of heat insulation material contained therein by providing protuberances on the walls enclosing said material which project into said material and thereby inhibit its movement parallel to said walls.
Claims3
An exhaust gas purifier comprising:
- an outer shell surrounding an inner shell defining a reburning chamber,
- a support casing surrounding and spaced from said outer shell,
- a heat insulating material in the space between said outer shell and support casing,
- a network of elongated outwardly directed projections formed on the outer surface of the outer shell, a network of elongated inwardly directed projections on the inner surface of the support casing, the projections of both of said networks being positioned diametrically opposite each other,
- the projections on each of said support casing and outer shell forming pockets which partially receive and substantially inhibit displacement of said insulating material during normal use of said purifier.
