The SCR system is located in the exhaust path, typically within the HRSG where the temperature of the exhaust gas matches the operating temperature of the catalyst. The operating temperature of conventional SCR systems ranges from 400 to 800° F. The cost of conventional SCR has dropped significantly over time — catalyst innovations have been a principal driver, resulting in a 20% …
lexie@zozen.com > Get A Quote >As it relates to steam and per Section I of ASME, a power boiler is “a boiler in which steam or another vapor is generated at a pressure of more than 15 psig (100 kPa) for use external to itself,” and a heat-recovery steam generator (HRSG) is “a boiler that has as its principal source of thermal energy a hot gas stream having high-ramp rates and temperatures such as the exhaust of a gas turbine.” HRSGs are …

So, it's important to limit and control this temperature to maximize parts life while still producing as much power as possible. The calculations include things …

So much high-temperature energy is now available to evaporate, superheat, and reheat steam that some high-level energy must be reserved to fully economize all of the steam being generated. The solution to this problem is to add feedwater heaters as shown in Fig. 4.12.

The stack temperature of a 4-pass boiler will be lower than the stack temperature of a 2 or 3-pass boiler, of the same basic design, operating under similar conditions. Because of this fact, the 4-pass will have higher efficiency and lower fuel cost
