Abstract
PURPOSE: To reduce deposits and to avoid influence of thermal stress, by providing a partition parting a casing into two chambers, suspending double tubes, introducing a high temperature gas from the upper chamber into the double tubes, and letting cooling water flow countercurrently.
CONSTITUTION: The high temperature gas enters at an inlet 6, flows down through an inner tube 13 of each double tube, is released at a lower end of the double tube 2 into the lower chamber, ascends along an outer tube 14, and then is discharged from an outlet 7. Water is supplied through a supply tube 8, branch tubes 9 and spaces 16 of the double tubes 2 and is delivered through branch tubes 10 into a boiler drum 12. During this period, heat exchange occurs and the gas is cooled while the water is heated. By this constitution, the high temperature gas containing dust is cooled rapidly to a temperature at which side reactions are slowed enough, then the gas is turned to ascend while dust is separated and therefore deposits can be reduced. As the double tubes are suspended from the partition, the thermal stress will be obviated. Thus a double tube type heat exchanger suitable for a waste heat boiler is obtained.
