Performance Prediction for Industrial Boilers

By Viswanathan Ganapathy, boiler consultant |

Understanding boiler performance calculations can allow engineers to improve the operation of their facility’s steam system and better engage with boiler-system vendors Chemical plants, petroleum refineries, power plants and cogeneration systems use oil-and-gas-fired steam generators, fluid heaters and waste-heat boilers of various types. Understanding how a boiler behaves with variations in parameters such as capacity, fluegas flow, inlet gas temperature or steam pressure can help plant engineers evaluate boilers better and understand why failures occur in crucial boiler components, such as superheaters, evaporators or economizers. Also, better understanding of boiler behavior can help plant engineers identify the reasons for decreases in efficiency. Figure 6. HRSG gas-steam temperature profiles in the performance guarantee case (right) and field-data case (left)[/caption] Figures 1 and 2 show heat-recovery steam generators (HRSGs) of natural- and forced-circulation designs behind gas turbines. Figure 3 shows a typical fire tube boiler used in a chemical plant and Figure 4 shows an oil-and-gas fired steam generator. Figure 2. The diagram shows the components of natural-circulation HRSG and a forced-circulation HRSG[/caption] …
