Document Type and Number:
Japanese Patent JPH06193810
Kind Code:
A
Abstract:
PURPOSE: To make it possible to wash a scale staying part in the lower part of an evaporating tank so that the water permeability thereof be recovered and also to wash the whole of a water-immersed surface.
CONSTITUTION: After generation of steam, residual water in an evaporating tank 1 is drained off. After the draining, water is fed to the vicinity of a drain port 2 of the evaporating tank 1 and a scale staying part in the vicinity of the drain port 2 of the evaporating tank 1 is washed at least one time or more by making use of the pressure of the feed water.
