Combustion system e.g. fluidized bed combustion system for device for generating heat and/or electrical energy, has transport line that is formed in sections by line element whose inside is provided with several convex forming elements

摘要

The system (100) has a transport line for transporting gas-solid mixture into a combustion chamber (110) of combustion system. The transport line is formed in sections by a line element (140) whose inside is provided with several convex forming elements. The gas solid mixture is a mixture of air and sand or a mixture of air, ash, and sand. The transport line is provided as recycle line for partial recirculation of combustion residue produced during combustion of ash in the combustion process, and the gas-solid mixture is provided with combustion residue. Independent claims are included for the following: (1) a device for generating heat and/or electrical energy; (2) a method for feeding gas-solid mixture; and (3) a method for generating heat and/or electrical energy.
