Title:
CONTROLLER FOR FEEDING OXYGEN GAS
Document Type and Number:
Japanese Patent JPH11241806
Kind Code:
A
Abstract:
To permit the optimum control of feeding oxygen gas, by making the feeding point of oxygen gas only at one place.
The amount of dissolving oxygen at the inlet port side of an economizer 8 is measured to detect a difference between an objective amount of dissolving oxygen and generate a signal, in which a feed water flow rate signal FW is taken into consideration in the difference, to integrate the signal while a signal, in which the flow rate CW of condensed water is taken into consideration into the integrated signal, is generated to produce an oxygen gas flow rate commanding signal OD, then, oxygen gas is fed into the feeding point A of a condensed water system pipeline based on the oxygen gas flow rate commanding signal OD.
