Abstract:
The present invention is directed toward an anchor used to retain thin refractory linings in process vessels such as cyclones and the like. In its simplest sense, the anchor of the present invention has a curved central web and curved legs which together have a shape that approximates that of the letter C. The anchor also has straight arms extending outwardly from the central web which together have a shape approximating the letter W. The arms and legs improve the ability of the anchor to control the crack pattern that forms in the refractory after thermal cycling, thereby reducing catalyst ingress or coke formation in the cracks.
