Combustion of Coal by Gasification

Sub Topic: Coal and Biomass Combustion and Gasification

Results are reported from recent tests where hydrothermal flames spontaneously ignited in a Supercritical Water Oxidation (SCWO) Test Cell. Hydrothermal flames are generally categorized as flames that occur when appropriate concentrations of fuel and oxidizer are present in supercritical water (SCW); i.e., water at conditions above its critical point (218 atm and 374 °C). A co-flow injector was...

Title : Fundamental Investigation of Fuel Transformations in Advanced Coal Combustion and Gasification Processes

The goal of this project is to experimentally characterize the high-temperature transformations of coals and alternative solid fuels over a wide range of operating conditions in temperature, pressure, and gas environment. The project will provide the database needed to extend existing submodels of pyrolysis and char burnout to the new conditions anticipated in next-generation energy technologie...

Effect of Pressure on Ash Formation during Pulverised Coal Combustion and Gasification

In this paper, effects of the operating pressure on ash formation reported in the open literature have been reviewed. In particular, the recent significant advances achieved at the Cooperative Research Centre for Coal in Sustainable Development (CCSD) in Australia are highlighted. The operating pressure significantly influences the size and the chemistry of ash generated through its effects on ...
