A top-lit updraft gasifier (also known as a TLUD) is a micro-kiln used to produce charcoal, especially biochar, and heat for cooking. [1] A TLUD pyrolyzes organic material, including wood or manure, and uses a reburner to eliminate volatile byproducts of pyrolization.

The oven still needed to be lit by match and accidentally turning on the gas without igniting it could lead to an explosion. To prevent these types of accidents, oven manufacturers developed and installed a safety valve called a flame failure device for gas hobs (cooktops) and ovens.
For instance, a recent study in Kenya found that households that are primary LPG users consume 42 percent as much charcoal as households that are primary charcoal users. [42] When stacking is practiced, the introduction of clean cooking facilities may not reduce household air pollution enough to make a meaningful difference in health outcomes. [19]
