Using biodiesel fuels to reduce DPM concentrations; DPM results using various blends of biodiesel fuel mixtures in a stone mine

摘要

This paper discusses a collaborative effort among Mine Safety and Health Administration (MSHA) Industry, and the Kentucky Department of Energy to test diesel particulate matter (DPM) emissions and exposures when using various blends of biodiesel fuels in two underground stone mines. The study was initiated by the industry partner, with MSHA and National Institute for Occupational Safety and Health (NIOSH) providing support for study design, data collection and sample and data analysis. Project funding was provided by Carmeuse North America, Inc., and the Kentucky Department of Energy through the Kentucky Clean Fuels Coalition. The study evaluated mine DPM emissions when using various biodiesel to diesel fuel mixtures. Two types of biodiesel were evaluated, a recycled vegetable base biodiesel fuel mixture and a soy based biodiesel fuel mixture. Baseline conditions were established using 100% low sulfur No. 2 diesel.
