Stove testers finalised 07-08.07.2010

The first 9 volunteers from a secondary school class at the Samdek Euv High School, Tuk Vil Commune, Siem Reap were selected to test the stoves. The volunteers were from Krable Riel (3) and Tuk Vil (5) in Pouk District and one volunteer from a village in Kouk Chork Commune near to Siem Reap. The stoves were demonstrated to the students (who all contributed to the cooking in the families) and they were then asked if they would like to take part. They were all interested so the stove was taken to their house. After 3 weeks, the stoves will be randomly re-allocated so each participant has a new stove to try, then after another three weeks the stoves again re-allocated. There is a 3 part questionnaire which has a section to be completed by participant after each stove. The main stove user will be asked to complete the questionnaire.

Initial introduction to stove covered the following points about the stove, which is:
– a prototype, therefore still has room for improvement, and is not yet available
– designed to reduce fuel use
– designed to burn smokelessly
– designed to produce biochar

The demonstration then covered:
– set up and safety of system*
– fuel choice and preparation
– fuel for char production (where necessary)
– how to light (ignition)
– how to keep alight (operation during burn)
– determination of which stage the system is in to conclude burn (combustion / gasification / end of gasification for those which produce wood charcoal)

And discussion also covered an introduction to:
– global warming, and the contribution from biomass burning
– forest loss, and use of resources
– biochar and it’s potential uses

*although stones are recommended by the designer in the anila stove, during testing the stone used turned out to be concrete and began to break down / explode in the stove (the stove was extinguished before any damage was done!!!), so it was suggested that stones were not necessary!
