Combustion plant for burning lignite for steam production comprises combustion chamber enclosed by steam producer-tube walls and which evolves downwards into funnel

摘要

The combustion chamber funnel (3) terminates with a rectangular aperture under which a removal grate (7) is arranged, beneath which is at least one air box (10). Between the combustion chamber funnel and the removal grate is a grate combustion chamber (8) surrounded by gas tight walls. At least on the two face sides of the grate combustion chamber (8) immediately beneath the funnel aperture (5) are at least two devices (11) for nozzle feed of gas containing oxygen together with components for feeding the gas to the devices.
