Process engineering support - design and evaluation of steam turbines and steam systems |
Steam-ASSIST is Windows-based software designed to produce heat and material balances for entire steam systems dynamically when variables are changed. The program handles complex steam systems with multiple pressure levels, utilizing process steam, heating loads, steam turbines of both back-pressure and vacuum turbine types, vacuum steam surface condensing, boiler water pumping and deaerator heating systems. Steam-ASSIST uses a steam properties module to predict the steam and water thermodynamic properties from full vacuum to critical pressure and temperatures to 1200 degrees Fahrenheit. The software rigorously simulates the performance of individual turbines' drivers, assessing their steam requirements from point efficiencies or efficiency curves via Turbine Pow-r Rate-r. The software performs heat balances for blending the exhausts of turbines and let-down services, predicting header operating temperature and pressure conditions. Flash calculations are included for prediction of boiler blow-down recovery to lower pressure header systems. Steam-ASSIST integrates with drawing software to generate steam system flow diagrams dynamically as new calculations are performed. There is lno imitation of the amount of equipment that may be included in a simulation. The software was written to produce accurate steam system heat and material balance predictions for performance evaluations and for changes imposed by different operating conditions, and equipment modifications involved in plant assessment and retrofit design projects. |
