Diseño de un Sistema de Compactación de Biomasa de Cascarilla de Arroz y Aserrín, en la Producción de Bloques Sólidos Combustibles (BSC)

Abstract

A biomass compactor has been designed for the production of Solid Combustible Blocks (SBC), to be used by the Eco-Sur-Ecuador Foundation in the production of eco-materials. The biomass is composed of equal parts of rice husk and sawdust, the design comprises two stages: the physical-chemical analysis of the biomass, by means of established techniques, which allow to evaluate and specify it based on the NTE/INEN1160, 652, 160 and the second part, which by means of deduction determined the necessary dimensions that allow to design a compactor. From the biomass compaction simulation, we obtained results of Specific Weight, Ash Content, Compressive Strength, and the parameter we are most interested in controlling Moisture Content, with which we could perform mathematical calculations to define the design of the compactor, therefore it was established that it must have a feeder hopper of 0.55Kg/s, a mold of 114 mm in diameter, a 20Hp engine, with a r.p.m. equal to 3600 so that a hydraulic piston exerts a pressure of 280Bar. Reaching a compaction capacity of 151.2Kg/h, which would represent 2299.6m3 /day. In addition, an analysis of the investment costs of the briquetting equipment assembly was carried out, whose approximate value is 40502 usd. This amount could be recovered in the short term, thanks to the production volume. By simulating the compaction, it was possible to design the biomass compactor for the production of Solid Fuel Blocks. It is recommended to the Eco Sur-Ecuador Foundation the construction of the equipment because the production will supply its demand, as long as the indicated conditions are maintained.
