Ing. Desarro. [online]. 2020, vol.38, n.1, pp.163-180.  Epub 05-Jun-2021. ISSN 0122-3461.  https://doi.org/10.14482/inde.38.1.621.41.

The present work was carried out at "Raúl Cepero Bonilla" Meat Company in the province of Camagüey, Cuba, with the objective of evaluating the steam generation, distribution and consumption system. A value of heat losses of the pipes of 207 094.99 W was obtained due to lack of thermal insulation. With the proposal of the use of Mineral Wool insulation in the pipes that require it, these losses are reduced by 92.303%. The energy efficiency of the steam generator was 90.7% while the exergy was of 7.03%. With the proposal of the condensate recovery design, 475 015.5 liters of water treated per year would be saved, bringing a reduction in fuel consumption of 64 186.51 liters annually. With the improvements that are introduced in the system, a total economic saving of $ 94 172.78 Cuban pesos (CUP) per year is obtained, being of CUP $ 10 759.37 the total cost of the investment, which can be recovered in a period of 1.4 months. A Net Present Value of CUP $ 36 238 and an Internal Rate of Return of 71% was obtained, which qualifies the proposed improvements as profitable.
