Inquiry (采购产品): waste oil conversion I own a farm in Lafayette and am researching waste oil conversion of an existing oil fired warm air furnace in the house and a oil fired boiler in the barn. I know that I have to lengthen the fire box, the next step in converting or replacing the burners or nozzel etc. Any input would be welcome. **** Hidden Message ***** larry scheer 92 0old beaver run road lafayette, NJ 07848 USA Company: the farm at rainbow's end Phone: 973-903-8624 E-mail: larryscheer@earthlink.net **** Hidden Message ***** larryscheer@earthlink.net
