Combustion Characteristics of Coal-Water Slurry Droplets in High-Temperature Air with the Addition of Syngas

An experimental study of the ignition and combustion processes coal-water slurry (CWS) droplets based on coal enrichment waste in a high-temperature oxidizer at 650–850 °C with syngas addition was carried out. The fuel mixture finely dispersed solid combustible particles (coal sludge, 10–100 µm size) water. product biomass pyrolysis two waste-derived fuels laboratory gasifier. Composition controlled by precision analytical gas analyzer. feasibility co-firing CWS experimentally established. Under such conditions, process intensified 15–40%, compared to without chamber. greatest positive effect achieved adding obtained during pyrolysis. delay times are 5.2–12.5 s versus 6.1–20.4 (lower 15–39%) when ignited medium Based results obtained, concept for practical implementation technology syngas-modified is proposed.
