A copper based oxygen carrier prepared by impregnation on a highly porous alumina support (14.2wt% active CuO) has been tested in a 120kW chemical looping pilot plant. This oxygen carrier has already been under investigation in other pilot plants up to 10kW fuel power and showed very good...

The effect of co-combustion of Vietnamese anthracite with Australian bituminous coal on the performance of a commercial circulating fluidized bed boiler was observed in the Tonghae thermal power plant.

This paper presents a power plant concept based on an oxy-fired circulating fluidized bed combustor (oxy-CFBC) combined with thermal energy storage on a large scale. The concept exploits to full advantage the large circulation flows of high temperature solids that are characteristic of these...

The conditions for CO2 reduction in a circulating fluidized bed (CFB) oxy-boiler are studied, that is, operation with pure oxygen, diluted by recirculated flue gases to moderate the combustion process. Two cases are analyzed: the ready-to-convert case, a normal air-fired CFB boiler, only...

Recently, oxy-fuel combustion has received increasing attention as one of the short-term solutions for capturing CO2 from power plants. Despite their quick development, there are several issues that need further research. Combustion characteristics, heat transfer, emissions levels, optimum...

Oxy-fuel circulating fluidized bed combustion (CFBC) is an alternate technology to oxy-fuel pulverized combustion (PC), which has a number of advantages that can often make it a better choice for CO2 capture. This paper presents experimental results and operating experiences from a 0.8MWth...

The black liquor gasification based bio-fuel production at chemical pulp mill is an attractive option to replace conventional recovery boilers increasing system energy efficiency. The present paper studies circulating fluidized bed system with direct causticization using TiO2 for the...
