Selección del esquema de cogeneración para una industria de pescado enlatado. Caso Ecuador.

Abstract

The determination of the parameter β=1.868 (the ratio of heat output (Q=4,771x109 kJ\mes) and electricity consumed (W=2,549x109 kJ\mes) by the industry) was per-formed selection of more suitable cogeneration scheme for its application in the conditions of a fish canning industry. Considering that the proposed cogeneration scheme would represent a savings in US dollars for the company as well as the fuel subsidy and various economic and environmental points of view, were calculated, the time of amortization for several cogeneration schemes with steam Turbines (TV= 20,89 years), with gas turbines (TG= 3,16 years) and with internal diesel combustion engines (MCID= 2,72 years) concluding that as the first alternatives to be considered are internal combustion engines and gas turbines. Whereas thermal energy of the internal diesel combustion engine is very disjointed, and fish canning industry need steam parameters from 0.8 to 1.3 bar absolute so the tons of CO2 not-emitted to the atmosphere by the use of this technology (TV= 2137, TG= 4490 y IDCE= 4987), it was concluded that the cogeneration scheme with gas turbine is the most viable technology ecological and economically for this type of industry.  Index Terms Cogeneration, rate heat and power, repayment period, β parameter, fuel savings.
