METHOD FOR CORRECTING OF PHOSPHATE SOLUTION DOSES INTO BOILER WATER OF DRUM BOILERS Russian patent published in 2014 - IPC F22B35/00 

FIELD: heating.

SUBSTANCE: invention refers to heat-power engineering and can be used to correct doses of phosphate solution put into boiler water of drum boilers. Essence of the invention: phosphate solution is dosed by a dosing pump into the boiler water of drum boilers depending on the blowing rate. Specific conductivity of N-cationated samples of feed water and boiler water of a drum power boiler is measured. Concentration of phosphates in the form $$P{O}_4{}^{3-}$$ in the boiler water is calculated. Basing on the calculation results the phosphate solution doses are regulated by the dosing pump.

EFFECT: improved accuracy of phosphate solution dosing into boiler water, improvement of chemical water treatment, improved efficiency of equipment performance.
