Description

technical field [0001] The invention relates to a device and method for a magnetically controlled chemical looping combustion reaction, belonging to the field of chemical looping combustion. Background technique [0002] Chemical looping combustion technology is a revolutionary new combustion method, which decomposes the traditional combustion of direct reaction between fuel and air into two gas-solid reactions with the help of oxygen carrier. From a thermodynamic point of view, the combustion process is a process in which the working medium (oxygen carrier) of the thermodynamic system consumes a large amount of energy. The biggest potential to solve energy utilization and environmental problems is the combustion process, and chemical loop combustion breaks the traditional combustion technology and is a new and clean combustion technology. [0003] Chemical looping combustion reactors are divided into air reactors and fuel reactors. The basic characteristic of the porous c...

Problems solved by technology

This movement behavior causes the uneven distribution of porous oxygen carrier particles, thereby reducing the effective conversion of non-magnetic porous oxygen carrier and magnetic porous oxygen carrier. In addition, the reduced magnetic carrier cannot be separated in time, so that the gas fuel cannot participate in the reduction. The oxygen carrier is fully contacted, reducing the combustion efficiency of gas fuel
