Abstract The 2018 Wood Stove Design Challenge (WSDC) was held in November on the National Mall, in Washington D.C During this event, three wood burning stoves were tested to determine their emissions characteristics according to a protocol developed specifically for the event. The testing protocol was developed to challenge the stoves to perform well under loading conditions that are more representative of real-world use.
As part of the WSDC, our team measured the Particle Number Concentration (PNC) in representative flue gas samples using the TSI NanoParticle Emissions Tester 3795 (NPET). The NPET is a portable instrument with internal dilution and built-in catalyst for removal of volatiles. It uses condensation particle counter technologies to measure sub micron particles at concentrations below 5,000,000 particles /cm3. The NPET is currently used for in-use emissions and compliance testing of diesel-powered machinery with diesel particulate filters in accordance with the Swiss Regulation SR 941.242, which defines regulatory particle number concentration (PNC) limits.
In this work, we describe incorporating the NPET device in a non-regulatory sampling capacity along with other biomass sampling instruments, show the results of PNC measurements made during the sampling campaign, and discuss the trends in PNC emission which arise during different phases of the operational protocol. During the WSDC, our team also made measurements of the flue gas composition and the emission of Black Carbon (BC) species, which will be discussed separately.
