We confirm that Energy Advice has developed a Digital Twin for the glass melting furnace. Energy Advice has installed EA-SAS software, developed a mathematical model of the glass melting furnace, and commissioned it. Digital Twin model allows us to monitor glass furnace process remotely, also as control technological process in real time by providing optimum operation setpoints. Project benefits: reduced energy consumption for glass melting process, increased glass furnace life time, identified furnace maloperation, determined components efficiency. The project was implemented on time. We recommend Energy Advice as reliable partner for Digital Twin development and implementation.
