Design and Performance Analysis of a Thermal Energy Storage System With Steam Extraction and Electric Heating in a Coal‐Fired Power Plant

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To alleviate the impact of the instability of renewable energy power generation on the power grid, coal‐fired power plants (CFPPs) have to undertake peak shaving tasks, which puts forward high requirements for the flexibility of CFPPs. To enhance the flexibility of CFPPs to consume more renewable energy, this paper innovatively proposes a ...

Performance Investigation of Eco‐Friendly Refrigerant Mixtures as an Alternative to R134a in Vapour‐Compression Refrigeration System

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling

Ultrasound–Calcination Synergistic Control of (Ce, La)PO4 Catalyst Structure for Enhanced Low‐Temperature NH3‐SCR Performance

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, (Ce, La)PO4 catalysts were synthesized via an ultrasound‐assisted method. The effects of ultrasound duration and calcination temperature on the low‐temperature NH3‐SCR performance were systematically investigated. The results indicated that the (Ce, La)PO4 catalyst prepared with an ultrasound treatment time of 20 min and a ...

Effect of Temperature and Atmosphere on Agglomeration of Bed Particles in a Bubbling Fluidised Bed Burning Na‐Enriched Coal

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Agglomeration of bed materials during circulating fluidised bed (CFB) combustion or gasification of high‐alkali fuel is a practical challenge in industrial practice. This work investigates experimentally the effect of temperatures (700°C–900°C) and atmosphere (air equivalence ratios 1.61–0.53) on agglomeration in a lab‐scale bubbling fluidised
