1.	What is the function of boiler?(a) To burn the fuel in a confined closed system with the supply of air(b) To generate steam at varying pressure(c) To generate steam at constant pressure(d) To produce flue gases by burning fuel at a given pressureI had been asked this question in homework.My enquiry is from Function of Boilers topic in chapter Steam Generators & Accessories of Energy Engineering
Answer» Right option is (c) To generate steam at constant pressure For explanation I would say: FUNCTION of boiler is to generate steam at constant pressure as per the process REQUIREMENT. The steam generated MAY be nearly dry saturated or superheated steam. Constant pressure in the boiler is MAINTAINED by GENERATING the steam equal to the steam flowing out of the boiler.
