Cálculo del cambio en la eficiencia energética al producir G.L.G de alta densidad utilizando captadores solares como pre-calentadore

Abstract

The energy efficiency was calculated when producing high-density guadua laminate (GLG), using a solar collector as a complementary, alternative and/or substitute source for the generation of thermal energy used in the production process. Taking into account that this process consumes a large amount of electrical and thermal energy in its threads, the latter being used for 3 of the most important phases, which are: Curing, drying and pressing of the raw material. These threads currently obtain thermal energy with the consumption of fossil fuels, such as natural gas and/or with the burning of guadua waste, both generators of large amounts of carbon dioxide CO2, which directly affect the environment and, in addition, generate significant costs in production. To evaluate the energy impact that the implementation of a solar collector would have in the production process of (GLG) as a substitute, complement and/or alternative for the generation of thermal energy in the previously mentioned sub-processes, a phased development methodology was proposed in which the current (GLG) production process was characterized; the type of solar collector was identified, defined and calculated according to the energy need and subsequently the variation of the energy efficiency of said process in energy and financial terms was validated. With the latter, it was established that 12 years would be necessary to leverage the investment with the total savings from natural gas consumption. This scenario, although viable, does not represent financial feasibility, for which the scenarios were evaluated at 40 % savings and 100 % with reduction of the investment amount.
