1EXPERIMENT: BOILER EFFICIENCYOBJECTVES:To find the boiler efficiency of the given steam plantINTRODUCTIONSteam is the major source of power generation in steam engines o rsteam turbines. Steam isproduced from water by combustion of fuel in a boiler an employed for heating the building incold weather. The primary requirement steam generators in boilers arc are water must becontained safely and steam must be safely delivered in desired condition in regards to itspressure, temperature, quality and required rate. The boiler consists of a membrane coil fitted ina shell which is enclosed by an air jacket which then burning fuel heats up the water+ suppliedby high pressure pumps into steam. Boiler efficiency therefore measures how much combustionenergy is converted into steam engine. This is the difference between energy input and energyoutput.
