Document Type and Number:
WIPO Patent Application WO/2005/108864
Kind Code:
A1
Abstract:
The invention relates to a boiler and to a method for operating a boiler. To effectively prevent damage to the boiler wall, in particular by corrosion, the flow speed characteristic of a furnace floor flow running horizontally to the furnace floor is determined, a source region of the horizontal furnace wall flow on at least one furnace wall is determined and an insulating gas is supplied to the source region of the horizontal furnace wall flow, in such a way that an insulating gas layer, which insulates the respective boiler wall from the flue gas, is created by the horizontal extension of the insulating gas with the aid of the furnace wall flow.
