Sinopsis

The performance of two constant heat flux fouling probes of widely different configuration was compared by connecting them in parallel within a flow loop, in which a solution of styrene in n-heptane was circulated. One probe was 0.14-mm 304-stainless steel coiled wire mounted perpendicular to the fluid flow, while the other was an internally heated 10.8-mm diameter 304-stainless steel rod which formed the inner core of an annulus through which the fluid flowed parallel to the rod. In all twelve runs performed, local boiling occurred on the heat transfer surfaces. The fouling results from both probes were remarkably similar, which enhances their credibility as indicators of process behaviour, at least for chemical reaction controlled fouling.
