Method of operating a boiler

摘要

The method involves operating an assembly of burners (4) by stoichiometry or by excess air of 5 percentage, where the air introduced by the assembly of burners and an additional air injection system (5) represents excess air of 15 percentage. The air injection system is placed in downstream of the assembly of burners. The air is injected such that a sum of axial movement quantities of the injected air is constant along a wall (3).
