How to find out boiler efficiency and equivalent Ł To find out the efficiency of the boiler Ł To find out the Evaporation ratio The purpose of the performance test is to determine actual performance and efficien-cy of the boiler and compare it with design values or norms.
12/5/2020 · If the boiler contains an economiser & superheater is considered a single unit, then the efficiency is termed as the overall efficiency of the boiler. Boiler Power The American Society of Mechanical Engineers (ASME) has recommended that one boiler horsepower is equivalent to evaporation of 15653 kg of water per hour from and at 100° C.
