Three‐Fourths of Carbon Emissions From 2023 Record‐Breaking Wildfires in Canada Traced to Soil and Peat Combustion

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In 2023, wildfires burned vast areas in Canada, emitting large amounts of carbon (C). The area burned by the 2023 wildfires is the largest ever recorded in Canada, but the partitioning of C emissions between aboveground biomass and soil sources remains unknown.

Improvement of the turn-down ration of gas turbines by auto thermal on board syngas generation

Journal of the Global Power and Propulsion Society, 2017
The low reactivity of natural gas leads to a sudden increase of carbon monoxide (CO) and unburned hydrocarbons (UHC) emissions below a certain load level, which limits the part load operation range of current utility gas turbines in combined cycle power ...
