TLUD Champion

Design specifications include a cone-shaped controller for regulation of primary air, a riser that provides draft and directs flame to the pot, protects against wind and provides space for complete combustion; double-walled fuel canisters, second fuel canister available to extend cooking time once the first fuel load is finished; removable concentrator lid, tripod stand with pot rests and telescopic riser that can slide down and couple with the concentrator lid. The height of the stove is 280 mm and width 200 mm. The fuel container weighs 1.6 kgs.

TLUD stoves can accept a variety of dry, woody biomass as fuel. See the GIZ 2013 publication on Micro-gasification for a thorough analysis of appropriate fuels.

Full design specifications can be found in this video.

From the GIZ 2013 publication on Micro-Gasification:

Burn time for one batch of fuel depending on the type of fuel: over 75 minutes on 1,000 g of wood pellets or 45 minutes on 600 g of wood chips. It boiled 5 l of water without a pot-lid from 11°C in 19 minutes with 384 g of wood pellets or in 20 minutes with 368 g of wood chips at the Aprovecho Research Institute in February 2010.

In an effort to standardize cookstove performance an International Workshop Agreement (IWA) was established in 2012. The IWA created tiers of cookstove performance in order to communicate technical information more easily to the government, donors, investors, and consumers when making decisions. However, many manufacturers have not tested stoves using the newly adopted IWA performance metrics. See the Global Alliance for Clean Cookstoves for more information. The full IWA document can be viewed here.

Not specified. Wooden handles are featured on both the fuel canister and concentrator lid to prevent user contact with heated materials. Standard precautions should be exercised when handling any heated cooking device.
