Nitrogen Oxide Emissions of Boilers in Finland [PDF]

open access: yesJAPCA, 1989
This article discusses nitrogen oxide emissions from various types of boilers in Finland. The boilers have been classified into 61 classes according to their size, combustion technique, and main fuel. A specific emission coefficient (ng NO2/J = mg NO2/MJ) for each class has been determined, based on literature surveys and actual measurements. The total

Biodiesel nitrogen oxides emissions

open access: yesThe Journal of Zhytomyr State Technological University. Series: Engineering, 2018
The trend of using the alternative fuels is increasing because of the global warming. For example, biodiesel improves the balance of carbon dioxide on the planet and reduces soot emissions compared with diesel fuel. But using the biodiesel in internal combustion engines tends to show higher nitrogen oxides emissions compared with diesel.
