GERES: New Lao Stove Production, Monitoring and Use in Cambodia
Jean-François Rozis, GERES, November 16, 2006

GERES reports production of the New Lao Stove(improved charcoal stove for urban areas) for commercialization with no subsidy between October 2005 and September 2006 at 87 999 units for an average of average 7,333 units per month.
100 000 units are planned for the year 2007.

GERES uses the following plan for monitoring stove production and use.

Having come all the way to India to present a paper on this topic (Preliminary Tests on Charcoal Making-
Pyrolysis Gas Burners) it seemed appropriate to at least try and demonstrate the concept. So after the conference I spent two quick days in Phaltan, building, modifying and trying out a oil drum charcoal maker modeled after one I built back in Canada three years ago.

This shows the mostly full drum of cotton stalks. This trial did not work so we moved on to a denser fuel, bamboo.

Here the drum full of vertically packed bamboo is ignited on top. The drum has a few dozen small holes in the bottom for
primary air to promote the partial combustion, or pyrolysis of the bamboo. During startup no air is allowed into the drum from
below. The fire on top needs to be burning over the whole surface. Then a small hole is dug in the dirt at the bottom of the drum to allow some air up through the bamboo to the fire on top. This increases the fire intensity and causes the fire to move down into the bamboo below the top. After five or ten minutes the burner can be placed on top.

With the burner placed on top the flames are extinguished and the bamboo smoulders or pyrolyses. Notice the small opening in the dirt at the bottom of the drum.

As the United States biomass thermal and power industry continues to expand, new reliable technologies offering higher efficiency solutions must be introduced. The newly introduced EOS series biomass gasification boiler is among the most energy efficient of AESI’s high-performance, low-maintenance biomass energy plants. The EOS series provides thermal outputs ranging from 600,000 BTU/hr to 20 million BTU/hr, and can be staged to provide increased capacity.

Designed and built by the leaders in the biomass waste to energy market in Europe, Uniconfort, the EOS series builds upon over 50 years of experience and over 4000 successful installations throughout the world. When asked about the highly efficient EOS series, CEO of Uniconfort Davis Zinetti notes, “we must not forget that greater efficiency is associated with less CO2 production. Choosing EOS, therefore, means making a choice in favor of the environment.”

Research Report on BACIP Wood Stoves for High Mountain Areas
Designs for Traditional Houses in the Northern Areas, Including Warm Water Facility

The Building and Construction Improvement Programme (BACIP), operating in the Northern Areas of Pakistan, is a project under the Aga Khan Planning and Building Services, Pakistan (AKPBSP). The programme is financed by PAKSID, a collaboration between the Canadian International Development Aid (CIDA) and the Aga Khan Development Network. The BACIP Programme Director is contracted through the Netherlands International Development Co-operation Programme (DGIS). BACIP works in co-operation with other Aga Khan Development Network Institutions (AKDNI) in the Northern Areas and Chitral, Pakistan. During 1999 and 2000 some 40 staff members, consisting of architects, engineers and social workers, have been involved in the BACIP programme activities. In addition, more than 200 village-based male and female resource persons assist on a voluntary basis in the implementation of the programme.

The present programme (to end-December 2000) consists of the development and introduction of house improvements (more than 40 different types) for traditional and new houses which are useful for villages in remote areas. Technology and skills development among local entrepreneurs has been initiated to enhance the delivery of the house improvements locally. Participatory cluster and village planning is a part of the process as well and community discussions have begun for determining appropriate housing locations to avoid building in geographically hazardous areas. Parallel to these mainstream activities, attention has been given to the design of new schools. As many of the technologies being applied in the new school designs can also be applied in houses, the demonstration effect would have a high impact on the youth and future house builders.

The present report gives an overview of the different types of stoves that have been developed by BACIP. The designs are improvements upon the existing stoves in terms of durability, cost, fuel efficiency and manufacturing techniques. The designs have been repeatedly modified to suit the needs and acceptability of the people.

The BACIP stove (buchari) has been developed on the basis of the AKPBSP (formerly the Aga Khan Housing Board) buchari which was introduced about seven years ago and more than 10,000 installed in the region. The new models have been fitted with various options, such as the top-oven, improved chimney, warm water facility and various chapatti plates for making bread.
