Projecção de uma instalação de processamento de arroz usando biomassa como fonte de energia

Abstract

With the pressing need to enhance agricultural productivity in Mozambique, this paper introduces a promising project for a rice processing plant for a factory. Aiming for a low-cost and environmentally sustainable project, it is proposed to use biomass (rice husk) as the energy source for the facility, considering that biomass is abundant in the rice production fields. To carry out the project, an entire furnace fire tubular boiler was designed, which is responsible for powering a turbine-generator set of 150 kW of output power. This power, which is used to power components of the industrial facility. In order to provide a good drying of the rice during its processing, an artificial dryer and a tube bank type heat exchanger that is fed by the combustion gases at the exit of the boiler were dimensioned. After the installation dimensioning, the economic viability of the project was also evaluated. Finally, the conclusions regarding the results of the project and its recommendations were drawn.
