EcoZoom's Zoom Dura, model ZD-WMC26 burns wood and other dry, solid biomass. Like the Zoom Stove, it features an abrasion resistant and durable ceramic combustion chamber with a 10 cm in diameter vertical section that forces the gases to mix with the flame, decreasing harmful emissions. The Zoom Dura adds a refractory metal liner to the inside of the combustion chamber that protects the ceramic insulation, increases the life of your stove, and improves combustion efficiency. This stove also features a reinforced metal doorframe for increased durability and stove life and installation sockets on the doorframe to hold the improved stick support system. The Zoom Dura features a durable, reformulated 6-pronged cast iron stovetop that improves heat transfer for all pots including round bottom pots and woks. The bottom of the combustion chamber is lined with a custom fit replaceable, abrasion-resistant, and kiln-fired tile to increase the life of your stove.
