RESUMO
This work aimed to study the energy capacity of the cake originating from malt beer at different moisture levels for energy, through description and analysis of economic viability. Sample collection was made in a company located in the city of João Pessoa-PB. Physical and chemical analysis were carried out to determine the chemical composition, where it was found their consumption potential for both animal feed and for human consumption. The immediate analysis showed high levels of volatile materials and low content of fixed carbon. The samples were characterized according to the humidity, higher calorific value and density. Moisture content were obtained (50%, 40%, 30%, 20% and 15%) and gross calorific value ranging from 2656 to 5025 kcal.kg-1 for the highest and lowest humidity respectively. The proposed regression model was able to express in more than 98% the relationship between higher calorific value and moisture content, and more than 92% compared to gross calorific value and density. With regard to economic feasibility, can be seen that all schemes of work proposed for the new working configuration of boilers were viable and the most profitable decreased by 49.98% in the cost of natural gas, that is, an economy R$ 3,900,842.00 per year. You can check that the malt bagasse as an energy source is feasible.
