Abstract
This study investigates experimental temperature data with particular attention to (i) uncertainty (between different test runs) and the (ii) time-resolved variability (in the transient start-up and steady state operation phase) in a fixed bed, laboratory-scale (biomass) combustors with secondary air staging at different. Temperatures measured from up to four zones are analysed: the packed fuel bed, freeboard (primary LI, secondary LII) and/or exhaust stack (fouling module). The study finds that peak bed temperatures have relatively low experimental uncertainty, while uncertainty in freeboard temperatures varies more widely. Additionally, experimental uncertainty (across all conditions) is notably low, does not exceed 5.00%, and does not appear to be zone specific (packed bed to exhaust stack). In comparison, time-resolved temperature variability can be zone specific at some conditions even within steady-state operation phase. The paper offers valuable insights for biomass combustion testing particularly when multiple runs are needed to collect fouling deposits over different air staging ratios.
