Sentences with phrase «pulverized coal technology»

Simply put, we use pulverized coal technology, which grinds the coal to the consistency of talcum powder before it's used as fuel to heat the boiler that produces steam.

Not exact matches

I've talked a lot about my published work in (1) carbon sequestration soil work (trees and sorghum); (2) co-firing test burns in every major type of coal technology (cyclones, pulverized coal, IGCC) for SO2 and NOx reductions; (3) ethanol (for octane requirements not using lead or MTBE).

It is possible to capture CO2 emissions at these pulverized coal units, but the CO2 capture technology currently has performance and cost drawbacks.

Today the prevailing coal - based generation technology in the United States is pulverized coal, with high - temperature (supercritical and ultrasupercritical) designs available to improve efficiency.

The levelized cost of new coal plants already exceeds that of new NGCC plants, and «today's CCS technologies would add around 80 % to the cost of electricity for a new pulverized coal (PC) plant, and around 35 % to the cost of electricity for a new advanced gasification - based (IGCC) plant,» according to the EPA (77 FR 22415).

Unless something happens soon to tilt the balance toward more environmentally benign alternatives, nearly all of those power plants will use the old - fashioned, intrinsically dirty technology known as pulverized coal.

An alternate way to estimate reductions is to look at the incremental cost of a particular carbon - abating technology, e.g. building an IGCC coal plant and sequestering instead of building a pulverized coal plant.

For example, according to the National Energy Technology Laboratory (NETL), a new pulverized - coal plant (operating at lower, «subcritical» temperatures and pressures) reduces the emission of NOx (nitrogen oxides) by 86 percent, SO2 (sulfur dioxide) by 98 percent, and particulate matter by 99.8 percent, as compared with a similar plant having no pollution controls.
