In 2013, a mid-western US food plant\u00a0found a way to use its own waste water as an alternative\u00a0energy source.<br \/>\nWhen the city of Janesville, WI began constructing an anaerobic digestion system\u00a0at its waste water treatment facility, the city created a contract to sell conditioned\u00a0biogas back to the food plant.<br \/>\nUsing its own conditioned biogas, the food plant unlocked the ability to burn\u00a0self-produced alternative fuel. But in order for the project to be a success, the\u00a0plant needed a combustion system capable of handling such a unique demand.\u00a0Based on prior success with a similar plant., the plant owner&#8217;s\u00a0turned to Preferred Utilities and a team consisting of Leidos Engineering, LLC and\u00a0American Boiler.<\/p>\n<p>&nbsp;<\/p>\n<p>Preferred Utilities designed and supplied a complete combustion\u00a0system, including an API-800 Burner, a bio\/natural gas mixture piping train, and a\u00a0proprietary burner management\/combustion control system.<br \/>\nThe system was designed to burn either natural gas alone, or a mixture of\u00a0preferential biogas and supplemental natural gas. Because digester gas contains\u00a0sulfur and water, Preferred fashioned 316 stainless steel for all burner and piping\u00a0components to resist corrosion.\u00a0The combustion system\u2019s startup and operation procedure is governed by a\u00a0BurnerMate TS burner management\/combustion control system.<\/p>\n<p>&nbsp;<\/p>\n<p>The system\u00a0consists of Preferred Instruments DCS-III digital controllers and a GNE 5004-M-85\u00a0Flame Safeguard module.\u00a0The plant now employs a full metering combustion control strategy with FD fan,\u00a0VFD control, and oxygen trim. The combustion air demand is determined based\u00a0on the sum of the combustion air requirements established by the inputs of both\u00a0the natural gas and biogas flow rates.<\/p>\n<p>&nbsp;<\/p>\n<p>The combustion system now fires a natural gas\/biogas mixture, with priority given\u00a0to biogas based on availability established by supply pressure, thus maximizing\u00a0fuel cost savings for the food processing plant.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Food Processing Plant Saves Money by\u00a0Burning Alternative Fuel &nbsp; Many processing plants produce large amounts of waste water, causing plant\u00a0owners to rethink their energy use strategy.
