Four Custom-Fabricated RNG System Boiler Skids

A leading energy company that provides award-winning renewable energy solutions needed engineering, procurement, and construction (EPC) services to design and construct four dairy farm manure-to-renewable natural gas (RNG) facilities. A critical aspect of construction included the installation of a boiler heating system at each location to provide heat to the digester. Mead & Hunt provided design, fabrication, and custom manufacturing services to create four skid-mounted boiler systems. Each skid contains a 5,000 MBH gas-fired condensing boiler and a variable speed circulating pump to provide constant on-demand heat directly to the digester. We integrated process instrumentation and a remote I/O panel were integrated, simplifying on-site installation and reducing fieldwork. Prior to shipping the skids to the project sites, we designed, constructed, and installed a custom drop-over enclosure to protect the process equipment from the elements. Each custom-fabricated boiler system supplies 5,000 MBH heating capacity, providing the reliable heat source needed to maintain digester operation.
