Abstract

In the paper first results of a several years’ research programme into the combustion and fouling characteristics of Rheinish brown coals are given. As described, fouling of the heat transfer surfaces causes severe difficulties for power station operation. The deposit formation is strongly dependent on both the composition of the inherent ash of the fuel and the extraneous impurities. The phenomenon of fouling can be influenced by operating parameters like excess air level and mixing between fuel and combustion air. The temperature of the heat receiving surface as well as its geometry play an important role.
