The research project described in this paper first established that minute interconnecting voids in slag deposits were sufficiently large to allow penetration by water treated with a suitable surfactant. From this was developed a practical water washing procedure that has been adopted as routine maintenance in certain marine boilers. Subsequently, fundamental combustion studies established that the mechanism of deposition for indigenous oil-ash constituents is primarily one of molecular diffusion. This finding indicates that new and radical burner and boiler design concepts are needed to overcome operational problems when untreated high-vanadium fuel oils are burned. Also described is a program of research on fuel oil additives to alleviate the superheater slagging problem. This includes the evaluation of many additive materials in a laboratory combustion rig and the development of a particular magnesia-alumina formulation that has promise as a practical and effective additive. Several large power utility boilers are now operating regularly on additive formulations developed through this research program, and preliminary reports indicate a high degree of success"--p. 103. |
