Publishable final report of project JOR3-CT98-0198

The implementation of biomass as secondary fuel in existing pulverized fuel firings, for the reduction of net CO2 emissions, presents one main disadvantage. Due to the nature of the biogenic fuels, there is major concern about about ash deposition-related effects and excessive rates of corrosion in advanced plants.
The objective of the project was therefore to provide predictive tools for the specific operational problems slagging, fouling and corrosion in pulverized fuel co-combustion of biomass in advanced high temperature power utilities.

The investigations were mainly focused on analytical work on the feeding of the system, to establish the adequate analytical methods to be applied on the fuel for the prediction purpose. The information gained was correlated with the analytical work on the samples resulting from the experimental work.

Mechanisms for the formation of deposits and corrosion of materials in industrial boilers were in this way identified and schematized. Although no guidelines could be established for a complete and perfect prediction, due to the complexity of the problem, successful results were obtained in the overall comprehension of the phenomena and some prediction tools could be proposed.
