REFRACTORIES FOR OIL-FIRED FURNACES AND BOILERS1

Activated carbons from oil-fired fly ashes

Introduction. The aim of this investigation is to prepare activated carbons with good sorbent characteristics from oil-fired fly ash, looking for suitable activation processes to produce surface sites with high reactivity on the carbonaceous matrices [1-4]. In particular, the nitrogen surface sites, formed by gaseous ammonia reaction at 800°C, could greatly increase the adsorption of gaseous sp...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Oxy–Fuel Combustion in the Lab–Scale and Large–Scale Fuel–Fired Furnaces for Thermal Power Generations

Mutagenicity in emissions from coal- and oil-fired boilers.

The mutagenicity of emission samples from three oil-fired and four coal-fired boilers have been compared by using the Salmonella/microsome assay. Very little or no mutagenic activity was observed in samples from five of these boilers. The sample from one oil-fired boiler showed mutagenic activity of about 500 revertants/MJ, and the sample from a coal-fired fluidized bed combustor had an activit...

Hot Corrosion Behavior of Magnesite – Chromite Refractories Used in Reverberatory Furnaces at Sarcheshmeh Copper Complex

Iran’s Sarcheshmeh copper industries with an annual production of 120,000 tones are the biggest of it’s kind in South Asia. The main method of production is pyrometallurgical matte making in two reverberatory furnaces which use direct–bond magnesite-chromite refractories supplied by German and Austrian companies. Following a recent major overhaul, bricks in contact with slag, matte and furnace ...
