Solid-Fuel Stove Testing

摘要

Stove testing is important and necessary. Lab tests provide valuable information, but are inadequate for predicting field performance. Field tests are needed, including controlled cooking test protocols and kitchen performance test protocols. The objectives of our testing are as follows: (1) determine if stoves have improved fuel efficiency and lower pollutant emissions compared with traditional stoves; (2) provide useful information to PCIA (Partnership for Clean Indoor Air) partners and others disseminating stove technology in the field; and (3) compare test results with a PCIA partner, Aprovecho Research Center, using a standard test protocol. We tested 14 stove/fuel combinations for performance and emissions. We used the WBT (Water Boiling Test) protocol; captured emissions with a hood and duct system; measured CO2, CO, and THCs (total hydrocarbons) with CEMs (continuous emission monitors); measured PM (particulate matter) with the filter method and ELPI (Electrical Low-Pressure Impactor); and sampled PM for OC/EC (organic carbon/elemental carbon) analysis. The stoves tested were as follows: A Ecostove, B VITA stove, C UCODEA charcoal stove, D World Food Program (WFP) rocket stove, E 3-stone fire, F Philips stove, G 6-brick rocket stove, H Lakech charcoal stove, I NLS stove, J UCODEA rocket stove.
