Title:
ROTATING TYPE REGENERATIVE AIR PREHEATER
Document Type and Number:
Japanese Patent JP3422044
Kind Code:
B2
Abstract:
PURPOSE: To uniform the flow of gas of high temperature flowing from a gas inlet duct to a heat exchanging element and to minimize the temperature difference in the circumferential direction and radial direction of the heat exchanging element.
CONSTITUTION: A dummy duct 30 extending in the direction opposite to a gas duct circumferential wall through-pass part 29 of a primary air outlet duct 11a is connected to the primary outlet duct 11a arranged within a gas inlet duct 13, and a dummy duct 32 extending in the direction opposite to the through- pass part 31 of the duct circumferential wall of the secondary air outlet duct 11b is connected to a secondary air outlet duct 11b arranged in the gas inlet duct 13. In addition, guide vanes 33 for guiding high temperature gas toward the central part of a heat exchanging element 3 is fixed outside the secondary air outlet hood 7b arranged within the gas inlet duct 13.
