In 2015, we conducted a capacity-building consultancy for CRT/N Regional Stove Testing Center to add a black carbon measurement system, calibation gas manifold, and quality assurance plan for laboratory stove emission testing. Project tasks included procuring, delivering, and installing equipment and providing hands-on training and remote support. Funding was provided by Global Alliance For Clean Cookstoves. 

 

A black carbon sample train was added to CRT/N's existing Laboratory Emission Measurement System (Aprovecho LEMS). Filter samples of particulate matter are analyzed for black carbon at CRT/N using a Magee Scientific Sootscan OT21 transmissometer. 

 

The calibration gas manifold provides metered flow of calibration gas for performing gas sensor calibrations. The manifold can also be used to mix up to 4 gases so calibration gas mixtures can be produced using locally avaialable compressed gas cylinders, instead of importing specialy calibration gases.

 

 

In 2017, we conducted a consultancy for Renewable Energy Test Station Regional Stove Testing Center to add a calibation gas manifold for laboratory stove emission testing. Project tasks included procuring and installing equipment and providing hands-on training and remote support. The calibration gas manifold provides metered flow of calibration gas for performing gas sensor calibrations. Funding was provided by GIZ.

We conducted a field campaign to measure emissions from biogas, LPG, and wood cookstoves during uncontrolled cooking events in Nepal households in 2017 and 2018. Emission species that were measured include CO, CO2, PM2.5, organic carbon, elemental carbon, as well as particle light absoprtion and scattering. Biogas composition (CH4, CO2) was measured to determine carbon fraction and heating value. Household energy consumption and stove usage were measured to calculate household level and village level emission rates. The project was commissioned and funded by CCAC and CCA. The results were presented in this CCA webinar. An open access journal article can be downloaded here.

The Ratnoze2 portable sampling system was constructed for measuring brick kiln emissions of CO, CO2, SO2, PM2.5, organic carbon, elemental carbon, and particle optical properties. The instrument was delivered to CAEM in Colombia in 2016, followed by a one month field campaign that served as a training for CAEM, and provided new measurement results of kiln technologies in Colombia (report here). The project was funded by CCAC Bricks Initiative. CAEM continues to use the Ratnoze2 for monitoring brick kiln emissions to improve emission inventories and inform policies and programs that lower emissions.

The Ratnoze1 portable sampling system was constructed for measuring brick kiln emissions of CO, CO2, SO2, PM2.5, organic carbon, elemental carbon, and particle optical properties. The instrument was delivered to ICIMOD in Nepal in 2016, followed by a one month field campaign in Nepal and India for the purpose of testing the new equipment and sampling protocol, training ICIMOD, and providing new measurement results of coal and biomass kiln technologies in South Asia. In addition to the equipment and user manual, other deliverables of the project include the measurement results report, brick kiln emission sampling protocol, and brick kiln measurement guidelines. The project was funded by CHeRN and CCAC Bricks Initiative. ICIMOD continues to use the Ratnoze1 for monitoring emissions of brick kilns and other black carbon sources such as diesel agricultural pumps and vehicles.
