Flue gas diverter damper seal land

A diverter damper seal land assembly for installation in a flue gas duct defined by a casing wall, the diverter damper seal land comprising:

• a seal land including a single sheet of metal bent to define:
• a front seal land having a length, an outer edge extending along its length and an inner edge extending along its length spaced from the outer edge and defining an elongate front sealing surface on its front side between the outer edge and the inner edge, the front seal land mountable in the duct by a connection to the casing wall;
• and
• a rear seal land having a length, a base edge extending along its length and an opposite edge extending along its length spaced from the base edge and defining an elongate rear sealing surface on its front side between the base edge and the opposite edge, the rear seal land extending at its base edge from the inner edge of the front seal land and spaced back and radially inwardly from the front seal land such that the rear seal land protrudes radially inwardly behind the front seal land;
• and
• a connector for connecting the front seal land to the casing wall.
