A PRELIMINARY HEAT-BALANCE COMPUTER PROGRAM CONFORMING TO SNAME T&R BULLETIN 3-11

This paper presents a Fortran IV batch-type computer program for the heat-balance calculation of a non-reheat marine steam plant. The program is in conformance with the commercial practice standards presented in SNAME Technical and Research Bulletin 3-11 "Marine Steam Power Plant Heat Balance Practices." The program treats the preliminary design heat-balance problem where feed heater outlet temperatures can be specified prior to the selection of specific heat exchanger characteristics. The system design includes a realistic auxiliary exhaust system utilizing auxiliary exhaust, bleed, augment, and unloading as available or necessary or both. The system must include a deaerating feed tank and may include up to two low-presure feed heaters and up to three high-pressure feed heaters. The program is designed so that further extension and adaptation to special needs can be easily accomplished. Program design results in a minimization of input data and very efficient running times. A verification example is presented. User's Instructions, Programmer's Documentation, and a listing are included as Appendices.
