Abstract
PURPOSE:To perform favorable steam temperature controls by making primary superheater temperature reducer outlet port steam temperature signals into precedent signals for steam temperature controls in a miscible burning type boiler. CONSTITUTION:Outputs of a load setter 14 makes arithmetic operations of primary superheater temperature reducer outlet steam temperature setting miscible burning ratio setter 15 are added with said set signals with use of an adder 17, which makes it obtainable target values of a primary superheater temperature reducer outlet port steam temperature detector which has been compensated by miscible burning ratio. The target values are brought in comparison with outputs of the primary superheater temperature reducer outlet steam temperature detector 9 with use of a primary superheater temperature reducer outlet steam temperature controller, which makes it possible to obtain precedent signals. Addition of the precendent signals together with temperature control outputs obtained out of a main steam temperature controller 8 is made by an adder 10, which additional outputs control the opening degree of a water infusing valve 4.
