GTZ 3rd EAST AFRICA REGIONAL ENERGY MEETING,Addis Ababa, Ethiopia, 27th – 30th October

Andreas Michel, Energising Development, GTZ
Combustion of wood
- Wood consist mainly of carbon, hydrogen and oxygen (CH2O)x
- Results of complete combustion: CO2, H2O and heat
BUT: 'Cooking stove never achieve 100% complete combustion'
There are more combustion products in incomplete combustion like:
- CO, NO2, Small particles
- Formaldehyde, Acrolein, Benzene, Toluene, Styrene, 1,3-Butadiene etc.
- Polyaromatic hydrocarbons
- CO and Particular matter (PM) have the biggest health impacts
Examples:
- CO – low concentration: Mild headache, fatigue, nausea, dizziness
- CO – high concentration: Death within one hour
- PM: strong effects to respiratory system
Annualy X.X mio people die due to being exposed to incomplete combustion every day
IAP and improve stoves
- Rule of thumb:
“stoves with less fuel consumption emit less pollutants”
“chimneys reduce IAP signicant”
- EnDev relevant stove ( reduced wood consumption) should have reduced emissions, too
- Evidence of the improvement through CO and PM measurement:
--> Improvement against Baseline
IAP – Measurement Devices
So far:
- seperated devices for PM and CO measurement
- Data analysis difficult
Now:
- One device for PM and CO measurement
- Data analysis simple using MS Excel
- But interpretation needs to be done
Procedure in the field:
- Mount devices
- Switch on, close lid
- Perform test, take notes in parallel
- Open lid, switch off
- In parallel: fill protocol manual
Data analysis
- read data from SD card and press “Process data” button in MS Excel
See, analyse and interpret results
- Careful as calibration of device might be expired
Aprovecho IAP meter
- Demonstration
- 1st tests
- results
IAP measurement
- Understand results
- Check for negative values
- Be critical, don’t trust what you read without crosschecking
