Document Type and Number:
Japanese Patent JP2873742
Kind Code:
B2
Abstract:
In an air preheater with a large lower cold end center section and a smaller, upper hot end center section, the connecting plate duct assemblies on both the hot and cold end are made the same height rather than to have cold end connecting plate duct assemblies which are larger and equal in height to the cold end center section. This minimizes the design and manufacturing costs and provides cold end connecting plate duct assemblies which are smaller, lighter and easier to handle. This then requires that the housing panels around the outside of the rotor be longer to reach between these connecting plate duct assemblies. At the ends of the hot and cold center sections are main support pedestal panels which support the hot end center section above the cold end center section. These main support pedestal panels together with the housing panels complete the rotor housing. In order to compensate for the difference in the height of the cold end center section and the hot end center section and the resulting difference in the distance between the hot and cold center section and between the hot and cold connecting plate duct assemblies, the main support pedestal panels include offsets which extend downwardly along the sides of the cold end center section to meet with the cold end connecting plate duct assemblies.
