Crushed Coal Gasification Combustion in a Cyclone Slagging Combustor.

Journal of the Japan Institute of Energy, 1993
This paper describes the experimental results of crushed coal firing two-stage combustion with the primary stage of cycolone slagging combustion. Combustion experiments were carried out under various air equivalence ratios in primary combustion, in several experiment series with different coal type, coal feed rate and coal in-jection azimuth.

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

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

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.
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
