Understand what boiler efficiency means, how a boiler uses fuel energy to produce steam and what information is needed before starting an efficiency calculation.
Learn the complete Direct Method step by step, from collecting boiler data to calculating useful steam heat, fuel heat input and final boiler efficiency.
Learn how to calculate boiler efficiency by identifying and calculating the major heat losses from the boiler and then determining the remaining useful efficiency.
Bring the complete calculation process together and apply it to a practical factory-boiler example, including result checking and performance interpretation.
