Title:
INVESTIGATION OF THE RELATIONSHIP BETWEEN BOILER WATER CHEMISTRY AND TURBINE BLADE PITTING
Corporate Author:

Report Date:

Abstract:
Tests were conducted on the DD-15 and LPH 2 boilers as well as on plant boilers to obtain data on the solids concentrations in the steam condensate. Analyses were conducted only during end-point moisture carryover evaluations on the boilers when they were steamed at overload and high water levels with high boiler water dissolved solids permitting temporary carryover. Results showed that the Na concentration in the steam at the superheater inlet was higher than at the outlet suggesting that soluble salts remain in the superheater. Test results indicated that a there is no preferential carryover of NaCl with the steam b no carryover from alkalinity would result in boilers receiving the proper boiler water treatment c carryover should not be a problem on boilers at normal water levels with normal boiler water dissolved solids even at overload steaming conditions and d no preferential carryover of salts normally found in 600 and 1200 psi boilers should occur.
