Resumen

PEREZ-BAYER, Juan F.; GRACIANO-BUSTAMANTE, Diana S.  y  GOMEZ-BETANCUR, José A.. Energy and emissions characterization of an eco-efficient biomass cook stove at different altitudes. Ingeniería Mecánica [online]. 2013, vol.16, n.3, pp.227-237. ISSN 1815-5944.

Around 2.5 billion people depend on wood as their main fuel for heating and cooking.In this work is studied the effect of altitude (678 and 1976 meters above sea level) on energy performance and emissions of an improved wood stove under standardized cooking tests. The experiments were carried out under the Water Boiling (WBT) and Controlled Cooking (CCT) Tests. The efficiency decreased about 24 % with increasing altitude in WBT, and specific fuel consumption increased 27.3 % due to the air density changes. Regarding the controlled cooking test, the specific fuel consumption and specific emissions increased by 15.3 % and 16 %, respectively. It is highlighted that altitude significantly affects the "Plancha" wood stove behavior. Specific emissions increased at higher altitudes, so it is necessary to redesign wood stoves according to their geographical location in order to optimize the cooking process.

Palabras clave : eco-efficient cook stove; biomass; combustion; altitude; energy and emissions; WBT-CCT cooking tests.
