Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

On the propagation limits and speeds of premixed cool flames at elevated pressures [PDF]
Combustion and Flame, 2017 Abstract The flame speeds and propagation limits of premixed cool flames at elevated pressures are numerically modeled using dimethyl ether mixtures. The primary focus is paid on the effects of pressure, mixture dilution, computation domain, and heat loss on cool flame propagation.

Influence of gas compression on flame acceleration in the early stage of burning in tubes
, 2012 The mechanism of finger flame acceleration at the early stage of burning in tubes was studied experimentally by Clanet and Searby [Combust. Flame 105: 225 (1996)] for slow propane-air flames, and elucidated analytically and computationally by Bychkov et ...

Thermal Calculations for Co‐Firing of Hydrogen/Ammonia and Coal in 660‐MW Coal‐Fired Boilers
Asia-Pacific Journal of Chemical Engineering, EarlyView.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 ...
