Presently studying for 1st class exam - one type of question (SOPEEC)has to do with forced-circulation boilers: "Sketch & describe how to protect orifices in waterwall circuit from plugging". I have never been involved with one of these boilers in my experience and cannot find any good information about them. Any help would be much appreciated. Regards; P.H.
