Abstract
A grate bar for an incinerator having a grate bar base body and a high temperature resistant cover plate covering the grate bar base body at least on a surface portion which in operation points to a combustion chamber. The cover plate is separated from the grate bar base body by a thermal insulating material. In the grate bar base body a cavity is inserted in a side pointing to the cover plate and/or in the cover plate in the side pointing to the grate bar base body, which cavity is at least partially filled with a ceramic fiber insulating material. The invention further relates to a method for producing such a grate bar.
Claims15
A grate bar for an incinerator, comprising
- a grate bar base body, and
- a high temperature resistant cover plate covering the grate bar base body at least on a surface portion which in operation is exposed to a combustion chamber,
- the cover plate completely covering the grate bar base body in a front foot region, on a forward head side and on an upper side region of the grate bar base body,
- the cover plate being formed in two parts including an upper part plate and a head part,
- the upper part plate and the head part adjoining one another at a width-wise extending separation point located on the head side, the separation point running transversely to a longitudinal direction of the grate bar base body at an approximate mid-height between the front foot region and the upper side region of the grate bar base body.
A method for producing a grate bar for an incinerator, comprising
- completely covering a grate bar base body with a high temperature resistant cover plate at least on a forward and an upper surface portion which in operation is exposed to a combustion chamber, the cover plate being manufactured in two parts including an upper part plate which covers the grate bar base body in an upper side area and on a forward head side of the grate bar base body up to a separation point, the separation point running transversely to a longitudinal direction of the grate bar base body on the forward head side at an approximate mid-height between a front foot area and the upper side area of the grate bar base body, and a head part of the cover plate which, starting from the separation point, covers the grate bar base body, a remainder of the head side and the front foot area of the grate bar.
