VERTICAL EXHAUST HEAT RECOVERY BOILER

摘要

PROBLEM TO BE SOLVED: To provide a vertical exhaust heat recovery boiler in which an exhaust gas flow passage is extended in the vertical direction and a group of heat transfer pipes are extended in the lateral direction crossing the vertical direction to seal the inside and the outside of a casing by a simple and inexpensive configuration. SOLUTION: The group of heat transfer pipes extending in the lateral direction and crossing for the exhaust gas flow passage formed by extending in the vertical direction of the casing are constituted so as to communicate with a header outside of the casing through a skin casing provided in a part of the casing. Thermal deformation of the group of the heat transfer pipes in the exhaust gas flow passage is absorbed by the skin casing to dispense with other seal mechanism and support mechanism around the casing in order to provide a simple and compact structure of a device.
