<p>The steam generator contains a circulatory fluidised-bed firing system with a combustion chamber, a dust separator, a bed cooler, after-heating surfaces in the path of the combustion gases, and other heating surfaces in the walls of the combustion chamber. Superheating (20,35,36) and intermediate heating surfaces (21,37,38) are installed in the after-heating system (19) and in the ash cooler (33,34). There can be several ash coolers connected in parallel, each supplied independently with ash by a separate metering mechanism (26,27).</p> |
