Comparison of Presumed PDF Models of Turbulent Flames

Journal of Combustion, 2012
Over the past years, the use of a presumed probability density function (PDF) for combustion progress variable or/and mixture fraction has been becoming more and more popular approach to average reaction rates in premixed and partially premixed turbulent

Scaling Up of a Lightweight Aggregates System Based on Recovery Raw Materials and With Fertilisation Capacity: From Laboratory Prototype to Semi‐Industrial Production

Applied Research, Volume 5, Issue 4, August 2026.
Improved glass meltability enabled semi‐industrial prototyping of a residue‐derived PK fertiliser. Firing produced mechanically stable micropellets and induced partial vitrification, pore‐network reorganisation, delayed P release, but restricted K availability; 6‐month field trials on turfgrass and Photinia supported agronomic feasibility.

Effect of different flue gas recirculation rates on low‐NOx combustion characteristics: A numerical simulation based on the combustion process of a gas boiler

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 3970-3983, August 2026.
Abstract NOx emissions from gas boilers severely impact the environment, and flue gas recirculation (FGR) technology can effectively reduce such emissions, yet the effects of different FGR rates on combustion performance and NOx formation remain unclear. This study thus used numerical simulation (via ANSYS Fluent, adopting the realizable k‐ε turbulence

Simulation of lean premixed turbulent combustion

Journal of Physics: Conference Series, 2006
There is considerable technological interest in developingnew fuel-flexible combustion systems that can burn fuels such ashydrogenor syngas. Lean premixed systems have the potential to burn thesetypes of fuels with high efficiency and low NOx emissions due to reducedburnt gas temperatures.

Acyclic Hydrocarbon α,ω‐Dienes: From Biomass and Plastic Upcycling to Carbocycles, Precision Polymers, and Cross‐Linked Elastomers

ChemSusChem, Volume 19, Issue 14, 29 July 2026.
Hydrocarbon α,ω‐dienes are mainly produced from steam‐cracking derivatives, but high costs, complexity, and environmental impact limit their use. This review highlights sustainable paths from biomass and plastic upcycling, and surveys catalytic transformations into carbocycles and specialty polymers, emphasizing their role as modular building blocks ...

Thermal Calculations for Co‐Firing of Hydrogen/Ammonia and Coal in 660‐MW Coal‐Fired Boilers

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 4, July/August 2026.
ABSTRACT To achieve a clean energy transition under the dual carbon goals, blending hydrogen/ammonia into pulverized coal boilers represents a key technological pathway. Different hydrogen/ammonia co‐firing ratios (5%–50%) are investigated for their impact on the thermodynamic characteristics of 660‐MW supercritical boiler at 100% and 20% boiler ...
