1. ENERGY PERFORMANCE ASSESSMENTOF BOILERS1 Bureau of ENERGY IntroductionPerformance of the boiler , like efficiency and evaporation ratio reduces with time, due topoor combustion, heat transfer fouling and poor operation and maintenance. Deteriorationof fuel quality and water quality also leads to poor PERFORMANCE of boiler . Efficiency test-ing helps us to find out how far the boiler efficiency drifts away from the best observed abnormal deviations could therefore be investigated to pinpoint the problemarea for necessary corrective action. Hence it is necessary to find out the current level ofefficiency for PERFORMANCE evaluation, which is a pre requisite for ENERGY conservationaction in Purpose of the PERFORMANCE Test To find out the efficiency of the boiler To find out the Evaporation ratioThe purpose of the PERFORMANCE test is to determine actual perfo
must be set up on the boiler-house floor. Samples must be taken and bagged throughout the test, the bags sealed and sent to a laboratory for analysis and calorific value determi-nation. In some more recent boiler houses, the problem has been alleviated by mounting the hoppers over the boilers on calibrated load cells, but these are yet uncommon.
