Design guidelines for targeted chlorination with fixed nozzles. Final report
These design guidelines enable utility and design engineers to select optimal design arrangements and equipment sizes for fixed-nozzle targeted chlorination in plant condensers and heat exchangers. Detailed design criteria with sample equipment specifications are included. The design process was based on previous conceptual studies of a variety of targeting schemes for delivering biocide in or near the condenser or heat exchanger waterboxes. The purpose was to minimize chemical delivery dosages while injecting adequate amounts for effective biofouling control in these plant systems. Final design criteria were developed, based largely on New England Power`s Brayton Point Unit 1 condenser retrofit design and engineering as well as on designs for three other condenser configurations. The design guidelines summarize results of EPRI research regarding the full-scale design.of fixed-nozzle targeted chlorination. Also provided are a discussion of the economic considerations, the detailed methodology and specifications for full-scale system design, and a step-by-step design example. The design process begins with the determination of an optimum chlorination schedule and the treatment dosage. A rough estimate of the desired number of nozzles is then made. Using an iterative computational process, refinements to the estimate can be made regarding the number of nozzles, nozzle sizing, and nozzle locations.
