## Abstract The dissolution rates of various types of magnetites are measured by a spectrophotometric technique allowing the determination of Fe^3+^/Fe^2+^ ratio as a function of time. Some tests are also performed on magnetite electrodes galvanically coupled to steel electrodes. The influence of

โฆ Synopsis
Different types of magnetites, both synthetic and from boiler tubes, are investigated by MSssbauer spectroscopy, X-ray powder diffraction, and dissolution rate determinations.
The dissolution tests are determined in deaerated 5% HCI solution, at 75ยฐC. By comparative examination of MSssbauer spectroscopic data with acid dissolution rate determinations, it appears that the dissolution rates of magnetites are higher the greater their deviation from stoichiometry.

Fly ash particles entrained in the flue gas of coal-fired boilers can cause serious erosion on the critical components along the flow path. Such erosion can significantly jeopardise operational life of the boiler. A first principle based theoretical model has been developed embodying the mechanisms
PFBC is one of the two important advanced fossil fuel technologies, now available. It permits the combustion of fossil fuels with extremely low emissions, while also achieving high electrical conversion efficiencies. However, relatively little is known about the ash characteristics, despite the exis
