Abrégé

Systems and methods for disrupting slag deposits formed on internal surfaces of hydrocarbon-fired combustion apparatuses (e.g., boilers), such as for easier removal thereof, and the treating compositions used therein are disclosed. In certain embodiments, the treating compositions include non-expanding and/or expanding synthetic carbon an optionally a corrosion inhibiting composition that reduces hazardous emissions. The slag deposit disrupting compositions/particulates are understood to combine or intermix with slag deposit forming materials formed during fuel combustion to co-deposit on boiler surfaces. The intermixed slag deposit disrupting compositions define an area or zone within the slag that weakens and/or reduces slag deposit integrity so that the slag deposits are more prone to flaking off, such as under their own weight, resulting in self-cleaning and/or are more easily removed using traditional cleaning or removal techniques.

Abrégé

A particulate coke composition including expandable coke is capable of removing deposits from rotating parts of a gas turbine engine while under full fire or idle speed. The coke composition may be introduced directly into the combustion chamber (combustor) of the gas turbine or, alternatively, anywhere in the fuel stream, water washing system, or the combustion air system. By kinetic impact with the deposits on blades and vanes, the deposits will be dislodged and will thereby restore the gas turbine to rated power output. If introduced into the compressor section, the coke particles impinge on those metal surfaces, cleaning them prior to entering the hot gas section where the process is repeated.

Abrégé

The present invention describes a nanoparticle size composition comprising at least one overbase complex of a magnesium salt and an associated organic boron complex. The present compound is an improvement over previous processes due to less complicated processing requirements and the high concentration of both magnesium and boron that results.
