| Abstract | This study analyses the performance of boiler in term of efficiency and energy losses using ASME performance test code 4.1. First, direct method means efficiency of the boiler is calculated directly by comparing useful energy with energy input from fuel. Second, indirect method considering all losses happened. The losses are due to flue gas, formation of water, moisture in air, moisture in fuel, radiation and convection, bottom ash, fly ash, incomplete combustion, and blow down. The study focused on a circulating fluidize bed boiler with a capacity of 486 TPH, @140 Bar, 540°C, and manufactured by foster wheeler. The study found that the actual operating efficiency of the boiler is 24% lower than design efficiency. The actual losses are 23% more than the losses specified by the manufacturer. The efficiency of the boiler can be increased by implementing certain activities to reduce the losses. It was found that by recovering the heat from the flue gas and using the heat for reducing the moisture content of bark by 30% about 1.5 $ can be saved for each ton of steam generated. |
