Title: Mechanisms of pyrite oxidation to non-slagging species. Quarterly report, October 1, 1994--December 31, 1994

Technical Report ·
OSTI ID:50943

This document is the second quarterly status report on a project conducted at the High Temperature Gasdynamics Laboratory at Stanford University and is concerned with enhancing the transformation of iron pyrite to non-slagging species during staged, low-NOx pulverized coal (P.C.) combustion. The research project is intended to advance PETC`s efforts to improve technical understanding of the high-temperature chemical and physical processes involved in the utilization of coal. The work focuses on the mechanistic description and rate quantification of the effects of fuel properties and combustion environment on the oxidation of iron pyrite to form the non-slagging species magnetite. The knowledge gained from this work is intended to be incorporated into numerical codes that can be used to formulate anti-slagging strategies involving minimal disturbance of coal combustor performance. The project aims to identify the mechanisms of pyrite combustion and to quantify their effects, in order to formulate a general rate expression for the combustion of pyrite that accounts for coal properties as well as furnace conditions.
