Coal and petroleum-derived components for high-moisture fuel slurries

Research output: Contribution to journalArticlepeer-review

Abstract

Slurry fuels based on coal and waste oil can be a viable alternative to coal in terms of environmental, cost, and energy performance. This paper presents a database of promising components for such fuels based on the experimental characteristics of their ignition and combustion. When analyzing the properties of high-potential components, we classified those components into four groups in terms of normalized ash and sulfur content. The components within each group have comparable ignition characteristics: ignition delay time, duration of complete combustion, maximum combustion temperature, and ignition temperature. Using the newly created database and results of experiments on highly heterogeneous fuels, one can predict the conditions and special aspects of their combustion in power plants of various capacities. The key outcome of the research is the procedural database and algorithm for selecting combustible components of slurry fuels with high relative efficiency for the heat and electricity generation in typical coal-fired power stations and boiler plants.
