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

open access: yesThe 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

Advancements and Challenges in Liquid Hydrogen Storage Tank Design for Maritime Applications

open access: yesEnergy Storage, Volume 8, Issue 5, August 2026.
ABSTRACT In line with the Paris Agreement and the IMO's decarbonization goals, the shipping industry has begun to focus more intensively on adopting alternative fuels to reduce emissions. Among these, hydrogen has attracted considerable attention, with liquid hydrogen (LH2) offering advantages in energy density and storage volume over compressed gas ...

Experimental and Numerical Investigation on Ignition and Horizontal Flame Spread for Recycled Plastic Pellets

open access: yesFire and Materials, Volume 50, Issue 5, Page 499-510, August/September 2026.
ABSTRACT Fires in recycling facilities are known for producing noxious fumes, having high heat release rates (HRRs), being difficult to extinguish and causing significant devastation to business operations. This research aims to provide experimental data and numerical models from which performance‐based designs can be developed for recycling facilities.

Effect of flue gas recirculation on the formation of unburned hydrocarbons in oxy-fuel and air flames in a semi-industrial scale burner

open access: yesFuel Processing Technology
Oxy-fuel combustion is a promising technology for reducing CO2 emissions in the energy sector. In this process, nitrogen from air is replaced with CO2, to ensure the purity of CO2 in the flue gas, altering the properties of the oxidizer.
