Advantages of Gasifier Stoves

Compared to solid biomass burning improved cookstoves, gasifiers have certain advantages:

Cleaner burning of solid biomass (considerable reduction of soot, black carbon and indoor/outdoor air pollution).

More efficient due to more complete combustion (less total biomass consumption).

Uses a wide variety of small-size biomass residues (no need for wood pieces or charcoal).

Easy lighting allows for cooking to commence within minutes, much faster compared to lighting charcoal.

There are also advantages compared to stoves operated on alternative fuels like liquid fuels or solar:

Solid biomass fuels are often available locally (affordable access at own convenience), easy to transport and easy to store after gathering.

Creation of gas from dry biomass can be achieved with very simple inexpensive technology directly in the burner unit, which is portable and does not require piping or special burner-heads (in most cases).

Performance similar to biogas (but not dependent on water and bio-digester) and approaching the convenience of fossil gases.

Furthermore, pyrolytic micro-gasifiers can create charcoal, which may be used in a charcoal stove, further processed into charcoal briquettes or used to improve soil productivity as biochar
