Abstract

This work was carried out in the “César Escalante Dellundé” Meat Company, in the province of Camagüey, Cuba, with the objective of evaluating its steam generation and distribution system. An energy efficiency of the fire-tube boiler of 87.41% was obtained, the heat losses to the environment of the non-insulated pipes amounted to 85,764.31 W, while the total hardness of the feed water to the boiler is 10.26 times above the standard value. Two alternatives for improvements were proposed, consisting of: 1) insulation of the pipes through which water vapor circulates with Mineral Wool, and 2) preheating the boiler feed water up to 70 °C. The application of both proposals of improvements will result in fuel savings of 23.56 kg/h, which allows stop releasing about 576 m3/h of combustion gases to the environment, along with an increase of the energy efficiency of the boiler of 0.10 %. The total investment cost necessary to implement the two proposed improvement alternatives reached a value of $ 8 117,35 Cuban pesos (CUP), which is recovered in 2.36 months considering the economic savings per year obtained, which amount to CUP $ 41 193.33 due to fuel not consumed in the boiler.
