METHOD OF DETERMINATION OF CONCENTRATION OF SOUR PRODUCTS OF ORGANIC IMPURITIES THERMOLYSIS IN STEAM OF DIRECT-FLOW POWER BOILERS

摘要

FIELD: power engineering.;SUBSTANCE: invention is related to quantitative determination of content of potentially-sour organic impurities in feed water of direct-flow boilers and may be used in thermal power plants. Method includes measurement of specific electric conductivity values of cooled samples of live steam and feed water and estimation of concentration of solution components, at that measurement is carried out in samples that are passed through H-cationite filter, determination is carried out by difference of two measured values of specific electric conductivity of cooled samples, and design concentration of solution component is concentration of conventional acetic acid, determined form the ratio: C_ac=153,6*χ_H ^LS-χ_H ^FW) where C_ac - concentration of conventional acetic acid, mg/dm³; χ_H ^LS and -χ_H ^FW - specific electric conductivities of live steam and feed water, mCm/cm;.;EFFECT: increase of data information value, received from automatic conductivity meters.;2 tbl, 2 dwg
