WHY ATTEMPERATION IS REQUIRED IN BOILERS ?
ANS - One of the methods used to control the final steam temperature in a packaged boiler is interstage attemperation.In this method,feed water of demineralized quality(having nearly the same TDS as the final steam)is injected in between two stages of a superheater system as shown above.Generally in a convective type of superheater design,the uncontrolled final steam temperature decreases as the load decreases,while with a radiant superheater system,t...
