Title:
WATER LEVEL CONTROL EQUIPMENT OF STEAM GENERATOR
Document Type and Number:
Japanese Patent JP3218384
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To eliminate follow-up delay in water level control and to conduct stable supply of clean steam in a steam generating system having a plurality of steam generators.
SOLUTION: A steam generating system comprises a steam generator 1 which heats first feed water stored in a trunk tank 1B, using the steam containing radioactivity as a heat source, and a steam generator 2 which heats second feed water stored in a trunk tank 2B, using the first feed water heated as the heat source. In water level control equipment of the steam generators which controls the water level of the trunk tank 1B storing the first feed water and the water level, of a drain tank 2C storing the first feed water condensed after it is heated, a control signal for controlling a flow regulating means which regulates the flow rate of the feed water is computed on the basis of a detected signal 38 of the water level of the trunk tank 1B or a detected signal 37 of the water level of the drain tank 2C.
