Title:
HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2017075752
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat exchanger capable of preventing fouling of a heat transfer part.SOLUTION: A heat exchanger 100 includes a steam supply part 2 for supplying steam, a heat transfer pipe 3 for exchanging heat with the steam, and a washing part 4 for washing the heat transfer pipe with washing water. The heat exchanger cools the steam, and recovers heat of the steam as hot water. The washing part sprays the washing water to the heat transfer pipe from above the heat transfer pipe. At that time, the washing water sprayed to the heat transfer pipe washes away or dilutes a contaminant adhering to a surface of the heat transfer pipe. Accordingly, the heat transfer pipe is washed, and fouling can be suppressed.SELECTED DRAWING: Figure 1
