WebApr 12, 2024 · This study examines the effect of grit blasting on the surface and subsurface characteristics of low-carbon steel substrates under dry and wet environments. Three types of wet environments have been simulated: tap water, saline water, and ethyl alcohol. The variation in average surface roughness with grit size, standoff distance (SOD), and …

Nox emission control in gas turbines for combined cycle gas …

Dry low emission (abbreviation DLE) is a technology that reduces NOx emissions that exhausts out of gas fired turbines. The amount of NOx produced depends on the combustion temperature. When the combustion takes place at a lower temperature the NOx emissions are reduced. Gas turbines with … See more Increased focus on environmental issues led to increased research on new and better gas turbines with water and steam cooling methods in the middle of the 1970s. The best technology could in 1980 reduce See more This is not a complete list, but examples of where and when DLE technology has been implemented or are planned to be implemented. In Europe DLE turbines were introduced offshore in Norway in 1998. All … See more WebJan 1, 1996 · A leadership position in dry low emissions (DLE) technology is being claimed by Rolls-Royce Industrial & Marine Gas Turbines.

WebAvailable combustion-based NOx control options for syngas-fired turbines are more limited than those available for natural gas-fired turbines. The so-called Lean-Premix Technology 1, which permits the latter to achieve emissions as low as 9 ppm (at 15% O 2), is not applicable to IGCC gas turbines. Differences between syngas and natural gas ...
