Sentences with word «oxyfuel»

Vattenfall, a Swedish firm, is backing a technology called oxyfuel combustion, which burns coal in a nitrogen - free atmosphere.

The CCS will be built on the so - called oxyfuel technique, which Vattenfall is also using at its CCS demonstration pilot at the Scwarze Pumpe plant.

Within four years, the use of oxyfuels during winter had become compulsory in 35 cities across the US, even though they lifted petrol prices by as much as 15 cents a gallon.

In my previous comment on oxyfuel for industry I didn't mention that it also allows carbon monoxide to burn faster and so be used not just in low temperature boilers but in high temperature furnaces and gas engines as well.

The introduction of catalytic converters is more likely to be responsible, they argue, and oxyfuels actually cause higher levels of other pollutants.

To heat that boiler, the damp, crumbly brown coal known as lignite — which is even more polluting than the harder black anthracite variety — burns in the presence of pure oxygen, a process known as oxyfuel, releasing as waste both water vapor and that more notorious greenhouse gas, carbon dioxide (CO2).

The oxygen has many uses but one of the most interesting is to run industrial furnaces in oxyfuel mode (particularly flameless), which results in fuel savings and a better end product.

In general, the three main types of carbon capture are pre - and post-combustion and oxyfuel combustion.

One thing that unites most of them is that the full effects of oxyfuels were...

But a growing body of opinion now challenges these claims, and in the absence of definitive research — or indeed, much research at all — the jury is still out on oxyfuels.

One, as at the Schwarze Pumpe, involves the oxyfuel process: burning coal in pure oxygen to produce a stream of CO2 - rich emissions.

Technologies, like amine scrubbers and chilled ammonia or oxyfuel, continue to be improved in the lab and at demonstration projects.

Other researchers point to anecdotal evidence suggesting that oxyfuels are a greater health hazard than conventional fuel.

Although CO levels have dropped in all but two of the cities, some scientists say that oxyfuels are not responsible for the improvement.

One, as at Schwarze Pumpe, involves the oxyfuel process: burning coal in pure oxygen to produce a stream of CO2 - rich emissions.

In Finland, VTT's Flexi Burn CFB project has developed and successfully demonstrated an oxyfuel combustion concept based on circulating fluidized bed combustion.
