Abstract

O alto custo do coque na produção de zinco no Forno Waelz da Votorantim Metais Zinco, em Juiz de Fora, ensejou a realização de testes em parceria com o SENAI CIMATEC para utilização de combustíveis alternativos na Planta Piloto, com o objetivo de mapear a viabilidade técnica e financeira para utilização na Planta Industrial. Ao longo dos testes foram utilizados: cavaco de eucalipto, chip de pneu e moinha de carvão vegetal. Os testes foram realizados com sucesso, apresentando oportunidades de substituição do coque usado atualmente por combustíveis alternativos, com potencial de ganho financeiro para VMZ JF. Este potencial precisa ser validado em testes em escala industrial.

 

The high cost of coke in zinc production in Waelz Kiln, at Votorantim Metais Zinco (Juiz de Fora/MG) led to test alternative fuels in Pilot Plant, in order to map technical and financial feasibility for use in Industrial plant. During the project were tested: eucalyptus chips, tire chips, charcoal powder. The tests were carried out successfully, with replacement opportunities of the current coke by alternative fuels.
