This has created a undue hardship for DAPI. This <br />furnace was being erected to operate in place of the <br />existing unit until permission was received from the City of <br />Ramsey to operate both simultaneously. The existing furnace <br />requires extensive maintenace needing approximately three <br />weeks to repair~ Thus, it is imperative that the new furnace <br />be completed before the existing furnace becomes inoperable <br />creating a financial hardship. <br /> <br />FACILITY DESCRIPTION <br /> <br /> DAPI is a secondary aluminum recovery facility that <br />recovers aluminum from various scrap material such as <br />castings, plate and aluminum/iron combinations. <br /> <br /> The facility has a Shaffer Aluminum Sweating Furnace, <br />Model 2500, that recovers an average of 400 lbs per hour of <br />aluminum from a totals.process input of 800 lbs per hour. The <br />furnace is a batch operated process that is charged with <br />scrap material by opening a section of the furnace. Two <br />3 million BTU per hour propane burners supply heat to the <br />system. The melted aluminum is recovered by pouring it into <br />molds for further purification by others. The remaining iron <br />and ash material are removed .and sent to others for <br />processing. This furnace has a maximum process input of.1600 <br />lbs per hour for an aluminum recovery rate of 1500 lbs per <br />hour.~ <br /> <br /> The furnace dust and fumes are removed with a W.W. Sly <br />Pactecon Model PC No. 218-6 Baghouse. The furnace emissions <br />enter a hood and are directed to the baghouse with an <br />induced draft fan where they are'removed. <br /> <br /> DAPI had been~erectinG a second aluminum sweating <br />furnace to supplement its existing furnace. However, this <br />construction was stopped by order of Jacqueline M. Deneen as <br />indicated above. This furnace will be 7 ft in diameter by 9 <br />ft long. It will be designed to recover an average of 600 <br />lbs per hour from a total process input of 1200 lbs per <br />hour. It will have the potential to process up to 2000 lbs <br />per hour of input material. Four 2 million BTU per hour <br />propane burners will supply heat to the furnace to melt the <br />aluminum. <br /> <br /> This' furnace wil.1 initially be used to replace the <br />existing unit. It will be ducted to the existing baGhouse to <br />remove any particulate emissions. DAPI will be applying to <br />the City of Ramsey for permission to operate both furnaces <br />simultaneously. DAPI is presently evaluating an afterburner <br />system to handle the emission from both furnaces. An <br />amendment to the Air Quality Permit will be requested when <br />the afterburner evaluation has been completed to operate <br />both furnaces at the same time. <br /> <br /> <br />
