WASTE HEAT RECOVERY BOILER, POWER GENERATION SYSTEM AND CLEANING METHOD OF WASTE HEAT RECOVERY BOILER

摘要

PROBLEM TO BE SOLVED: To facilitate work of cleaning a heat transfer pipe with water, to reduce a work time.;SOLUTION: A waste heat recovery boiler includes a duct 13 inside which exhaust gas circulates in a vertical direction, and a plurality of heat exchangers 10B, 11, 12A arranged in the duct 13 and having a plurality of heat transfer pipes 14 whose longitudinal axial direction is installed in a horizontal direction. The heat exchangers 10B, 11, 12A are installed as a group so that a temperature of exhaust gas circulating in the duct 13 or an external surface temperature of the heat transfer pipe 14 is within a range of 150-200°C.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
