- At typical green-field start Burns Energy Systems plant, will have a CAPEX requirement of about $950/production tonne/year. With local installation crews this number may be reduced. New installations can usually be justified on fuel and metal savings alone. An in-plant upgrade for a new 7,000 tonne/year addition with a bag filter is about $700 per production tonne with SCADA, automation systems, and silo homogenization included.
ROI - ROI on the Burns Energy Systems furnace retrofit into an existing plant is typically less than 12 months. For estimated fuel savings based on your production rate and fuel cost, please check the top graph on this page. Metal savings can be expected to be between 50 and 250 tonnes/year, dependent on your current conversion rate. ROI for a complete 7,000 t/year plant using Secondary Zinc to produce ZnO is usually about 18 months.
