Martin-Machinery's internal combustion engine CHP system was submitted by The Colorado Governors Office of Energy Management and Conservation (Denver, CO) for verification by the GHG Center. The reciprocating engine-based system will use renewable biogas fuel generated from an innovative and low-emission swine waste management technology, located at Colorado Pork, LLC (Lamar, CO). Electricity from the Martin-Machinery built 75 kW reciprocating engine will be used on-site, as will the heat generated from a stack gas heat recovery unit. Testing verified energy efficiency, emissions, and power quality performance.
