1.	Which reaction differs over feed and under feed system?(a) Changes occurring in physical properties of the system(b) Breaking of molecular structure(c) Changes in chemical composition(d) Existence of volatile matterThe question was asked during an interview for a job.My question is based upon Principle of Stoker topic in division Steam Power Plant of Energy Engineering
Answer» The correct ANSWER is (b) Breaking of MOLECULAR structure Easy explanation: The reactions which TAKE place in the incandescent zone of under-feed stoker is exactly same as in the incandescent zone of over feed stoker except some breaking of molecular structure of volatile matter. Part of the broken volatile matter reacts with the oxygen of air.
