摘要：This work presents a novel concept of reactor design in CLC technology. This is the second concept in a series of patents on the construction of air and fuel reactors. The first patent"The combustion chamber design of a duo-fluidized bed reactor with circulating solid oxygen carriers of the CLOU type" was presented at the 6th International Conference on Chemical Looping in Zaragoza, Spain in September 2022. The purpose of the presented solution according to the invention was to develop a simple reactor structure for the optimization of the chemical looping combustion process. According to the invention, the presented reactor dedicated to solid fuels combustion in the CLC system has two chambers of identical conical-cylindrical shapes, which are symmetrically and permanently attached with their upper conical parts to rotatably fixed transport pipes located on a common axis. The simple and compact design of the reactor makes it economic & easy to manufacture and takes up significantly less space than a classical unit designed for the chemical looping combustion process. The proposed design enables uncomplicated process control due to fewer auxiliary devices as compared to the previous designs used for process control. Moreover, the reactor according to the invention has a lower energy expenditure because it uses lower gas velocities for effective operation than in a traditional CLC unit. ?
