Which type of combustion aims to reduce emissions?

The Dry Low NOx (DLN) combustion technology is specifically designed to reduce nitrogen oxide (NOx) emissions during the combustion process. NOx emissions are a significant environmental concern as they contribute to air pollution and smog formation. DLN operates by controlling the combustion temperature and the availability of oxygen, thus minimizing the formation of NOx. This technology is particularly useful in industrial and utility applications where strict environmental regulations are in place.

In contrast, the other combustion types mentioned do not inherently focus on reducing emissions to the same extent. Diffusion combustion, for instance, is often less efficient in terms of emissions control. Can-Annular and Silo-Type combustion configurations may also not prioritize emissions reduction as their primary function. Therefore, the aim of reducing emissions, especially NOx, is most accurately represented by Dry Low NOx (DLN) technology.
