Deoxygenation in cycling fossil plants. Final report
- NWT Corp., San Jose, CA (United States)
In a previous EPRI study (Phase 1 of RP1184-9) at the Port Everglades plant of Florida Power and Light, it was demonstrated that minimizing shutdown oxygen levels at a cycling plant could reduce corrosion product transport to the boilers. A continuation of the program was performed to demonstrate the use of two forms of activated carbon to catalyze the hydrazine/oxygen reaction as a method to minimize the oxygen levels of cycling fossil plants. An activated carbon impregnated fiber overlay on a powdered resin precoat was tested at TU Electric`s Tradinghouse Creek Unit 1 and a carbon bed followed by a deep bed demineralizer was tested at Duquesne`s Elrama Unit 4. The improvement in attainable oxygen control was demonstrated and the effect on corrosion product transport during cyclic operation was evaluated. The study also demonstrated the application of a data acquisition system for prompt data assessment, control of chemical additions, identification of problems, and development of responsive corrective actions.
