How it works: A Biomass Boiler | Biomassmagazine.com

Apr 02, 2013 · Each tube is surrounded by water, and evaporates as the heated gas travels and doubles back through the tubes. From the fire tube section, steam travels through the top to be used as heat in buildings, or to power steam generators. At this stage, any heavy particulates, or fly ash, are dropped into a blower system that deposits them into the ash collector. The rest of the exhaust gas moves to the multicyclone collector. Collection Tubes
