The reversible exothermic reaction of CaO with water is considered one of the most promising reactions for high temperature thermal energy storage. In this paper, a novel technical design of a MW-scale thermochemical energy storage reactor for this reaction is presented. The aim is to provide an...

This work concerns a preliminary study of the combustion of chars made from two different biomass species, vine and kiwi pruning wastes. The study was performed in a fluidized bed combustor, operating in a bubbling bed regime. The pellets were manufactured in a different installation, Viseu...

Improvement of energy efficiency, reduction of operating costs, and reduction of harmful emissions released into the atmosphere are issues of major concern in modern energy plants. While air emissions have to be restricted due to tightening environmental legislation, at the same time it is ever...

Residues from oranges' plantations and processing may play an important role as biofuels for heat and power production in Mediterranean countries. The management of ashes produced during combustion is a great issue for the energy sector. Ash quality from lab-scale fluidized bed tests of these...

In this study MgO-promoted Fe2O3 hematite oxygen carriers were synthesized from various Mg sources and evaluated for methane chemical looping combustion. Particles suitable for fluidized bed flow reactor studies were prepared in the lab. Cyclic CLC tests conducted in the fluidized bed with MgO...

This paper presents the experimental results of the emissions of CO and CO2 using rice husks as fuel on different configurations of spout-sluidized beds namely, multiple-spouted and spout-fluid fluidized bed. The emission of pollutants from the multiple-spouted bed and spout-fluid bed was...

Olive kernel can play an important role as a fuel for heat and power production in the island of Crete, substituting a large part of conventional fuels. However, combustion of this biofuel may create operational and environmental problems related to its inorganic constituents. Thus, the thermal...

The present work reports studies on the mixing and combustion characteristics of cotton stalk (CS) with 10–100mm in length in a fluidized bed. Effects of length and initial weight percentage of CS, diameter of alumina bed material as well as gas velocity on the mixing characteristics of CS...
