Use of tools & equipments., , IV __ Relevant Course Outcome(s), ¢ Use relevant steam boilers., , V Practical Outcome, e Assembly and dismantling of boiler Accessoriés., , VI Minimum Theoretical Background, Boiler accessory like air pre-heater, economizer acts as heat recovery unit and extracts, 4 heat from flue gases from boiler. Super heater is employed for increasing work output, d from available steam as well as take of possible condensation in steam turbine thereby, avoiding erosion and corrosion of turbine blades., , VII Setup (Models) - 3 hee, , Name of accessory - Superheater, , (Note — Draw the sketch of the actual superheater / model of superheater of boiler available in your, , laboratory and label the components. In case components are not visible redraw and label the figure given, low) ., , °
