Fuel Efficient Stove Programs in IDP Settings - Summary Evaluation Report, Uganda
Academy for Educational Development for USAID, September 2007

Introduction: Evaluation Objectives

Around the world, conflict and natural disasters have displaced millions of people. Displaced populations fleeing to settlement camps and seeking safety in host villages often put great stress on natural resources, leading to environmental degradation and conflict with local populations. One of the greatest needs of all people affected by crisis, be they displaced, settled or on the move, is firewood or other types of fuel to heat their homes, cook their food, and treat water for drinking and food preparation. The risks endured (especially by women and children) collecting sometimes scarce wood resources constitute some of the most challenging and serious protection concerns both in IDP camps and in villages where the conflict over resources is high.

USAID’s Office of Foreign Disaster Assistance (OFDA) has been one of the key US Government funders of humanitarian agencies implementing fuel-efficient stove (FES) programs in IDP settings. The FES programs are intended to help the agencies accomplish various goals, such as improve food security or decrease deforestation, by reducing fuel consumption. However, the large number of implementers, their varying motives and degrees of expertise, and differing conditions within and among IDP communities have made it difficult for OFDA to determine the relative efficacy of the FES interventions and provide guidelines for USAID-funded entities working in IDP settings.

Therefore, OFDA enlisted the assistance of the USAID Energy Team to undertake a multi-phase evaluation in order to derive “best practices” for future FES interventions. While the primary purpose of this evaluation is to provide guidance to USAID-funded organizations, USAID hopes to inform the broader humanitarian community by sharing the results of the evaluation with them as well. Eventually, the best practices will be developed into a series of recommendations and toolkits for use by NGOs, donors, and other groups operating FES programs in IDP settings.

Stove Performance Report: Mayon Rice Hull Stove
Aprovecho research Center, July 18, 2005

INTRODUCTION:

This report serves to provide detailed performance measures of the smaller red model of the Mayon Turbo Rice Hull cooking stove including speed, fuel use, efficiency, and emissions produced. Stove performance is also considered in comparison to a laboratory open fire and the average of four similar wood burning stoves recently tested at the Aprovecho laboratory. Comments are included describing ease of use and recommendations for possible design improvement.

The Mayon Turbo stove reduces both Carbon Monoxide and Particulate Matter when compared to a carefully operated open fire. It is especially successful at reducing Particulate Matter.

160 grams of charcoal boils and simmers 5 liters/CF04 Stove
Lanny Henson www.lanny.us July 2, 2006

The CF04 Stove boiled and simmered 5 liters using only 160gr of charcoal and wood.

After several modifications to 4 different prototypes, it only took 150 gr of lump charcoal with 11% moisture and 10gr of wood to boil 5 liters of 83 degF/28.3 degC water in 45 min. That is 32 grams per liter to boil and simmer. At 1 hour after boiling the water was still simmering at 100 degC and after 2 hours the water was 205degF/96 degC. At this point I shut the air control and capped the pot module to stop the airflow and retain heat.

At 3 hours the water temp was 190 degF/87.8 degC and was 178 degF/ 81 degC at 4 hours.

Comparing the Charcoal Burning Rocket and Jiko Stoves (pdf)
Dean Still and Nordica MacCarty, Aprovecho Research Center, June 22nd, 2006

The charcoal Rocket Stove was compared to the Jiko-type charcoal stove sent from Ghana. 600 grams of Kingsford charcoal was placed in the stoves under the Aprovecho emissions hood. One test was performed on each stove for preliminary studies. The stoves are compared in the following graph for carbon monoxide emissions during a cooking task (to boil 5L of water and simmer 30 minutes).

Comparing Cook Stoves (pdf)
Dean Still, Aprovecho Research Institute, ETHOS January 2006

Performance benchmarks for biomass cooking stoves were presented at the 2006 ETHOS (Engineers in Technical and Humanitarian Opportunities of Service) conference by Dean Still, Nordica Hudelson and Damon Ogle of Aprovecho Research Center. The benchmarks will be useful to stove designers and developers to compare their stoves against many others. The benchmarks were derived from tests of 20 stoves (9 replications each) in work funded by Shell Foundation and the Partnership for Clean Indoor Air (USEPA).
