Examples of Unburned hydrocarbons in a sentence

  • Unburned hydrocarbons from the natural gas that are not fully combusted may condense to form PM.

  • Unburned hydrocarbons, i.e. fuel, and residues of fuel additives, may also remain after the combustion process.

  • Unburned hydrocarbons (HC) are one of the main pollutants released from internal combustion engines and cause many environmental and health problems[1, 2], for example, Volatile organic compounds ( VOCs) enter in the formation of ground level ozone ,ozone depletion ,and they act as greenhouse gases[3, 4] .

  • Unburned hydrocarbons, many as POM compounds, can exist in such systems and eventually be emitted through the source stack.

  • Keywords: non-thermal plasma, diesel oxidation catalyst, Light-off temperature, CO, Unburned hydrocarbons 1.

  • Unburned hydrocarbons: This metric scales the level of unburned hydrocarbons from 0 to 1.0 with the most uHCs with a ratio of 1.0. Similar to that of carbon monoxides but greater emissions are noted at earlier injection timings due to combustion of richer pockets of gas.

  • Unburned hydrocarbons tend to follow CO trends.It is important to note that combustors are developed for operability, performance, cost, and durability, with NOx and other emission levels being an added constraint.

  • Unburned hydrocarbons, carbon monoxide, carbon dioxide, sulfur oxides & nitrogen oxides are all products of combustion that provide the greatest threat.Carbon monoxide: Carbon monoxide is a highly toxic gas associated with incomplete combustion.The CO level in the flue gas depends solely on combustion efficiency and not on the fuel, the burners or the design of the boiler.

  • Unburned hydrocarbons are precursors in the formation of ozone and contribute to exceedances of federal and State ozone standards.

  • Figure 24.—Architecture-C : Unburned hydrocarbons emissions relative to baseline.
