Digester gas burns to keep anaerobic digesters at temperature, warm sludge flows through the process at 30 to 35 degrees C, and the administration block, lab and control buildings all need ventilation make-up air that is heated through the winter. Most of that warmth leaves the site in sludge, in exhaust and up the stack.

This article covers where the heat sits, how to recover it from sludge with a plate core, and why the hydrogen-sulfide-rich atmosphere dictates the materials.<\/p>\n<h2>Where the heat is<\/h2>\n<p>The two obvious sources are the digester and the building. Digester gas is rich in methane and is burned on site, but the digesters themselves and the outgoing digested sludge carry a steady 30-plus-degree thermal load that is normally wasted. At the same time the plant&#8217;s own buildings, the control room, lab, workshop and administration block, are ventilated hard and need warm make-up air in winter. <a
