HEAT EXCHANGING DEVICE

Japanese Patent JP3471274

B2

PROBLEM TO BE SOLVED: To provide a heat exchanging device that can stably maintain the flowing time of a heating medium in a heat exchanging chamber, especially the upper part of the heat exchanging chamber in which high-temperature gas circulates.
SOLUTION: The cross section of each of heat exchanging chambers 2 and 4 is made to have a rectangular shape, and each of trays 6 and 7 of these heat exchanging chambers 2 and 4 is made to be a titled tray without hole parts. The vertically adjacent trays 6 and 7 are bulged in horizontally opposite directions to each other. In the horizontally projected section of each of the trays 6 and 7, the cross section of the heat exchanging chambers 2 and 4 are covered widthwise, and an open part 24 is formed in the tip side lengthwise. The passage of gases 1 and 3 at the location of each of the trays 6 and 7 is limited to the open part 24, and the flow velocity of the gases 1 and 3 passing through the open part 24 is set to be approximately equal to the equilibrium velocity of free fall of a heating medium in the gases 1 and 3. Thereby, the flowing time of the heating medium 8 at the time when it falls through this open part 24 is secured long, and heat exchanges between the heating medium 8 and each of the gases 1 and 3 can be performed sufficiently.
