Objective Objectives of the Project In comparison with other renewable energy sources the thermal utilisation of biomass or waste Is an economical, sustainable and technical feasible option to contribute towards reducing the net C02 emissions, one of the principal goals of the European Union. Co- combustion of biomass or wastes together with coal in existing large-scale pulverised fuel firing systems offers several advantages, e.g. the possibility to utilise a large quantity of biomass at lower investment costs compared to systems exclusively fired with biomass. However, due to its wide range and properties, biomass as feedstock is a complicated fuel and there is increasing concern about ash deposition-related effects and excessive rates of corrosion in advanced plants. The objective of the project therefore Is to provide predictive tools For the specific operational problems slagging, fouling and corrosion in pulverised fuel co-combustion of biomass In advanced high temperature power plants. Technical approach The work program consists of experimental and analytical work on corrosion, slagging and fouling as well as related chemistry. In parallel experimental work and analytical methods will provide methods for pilot scale test procedures Applied chemical tools for analysis and the description of mechanisms will validate the experimental and analytical results. Corrosion tests will concentrate on the physical and chemical processes involved at higher metal temperatures. Eleven mainly Industrial or industrial orientated partners will investigate in close cooperation: . - the slagging and fouling potential of different fuel mixtures using various techniques in lab scale, pilot scale, and full scale facilities - the corrosion mechanisms in biomass-combustion by means of corrosion tests, fuel, deposition and gas analysis, using material samples in full scale and test facilities - chemistry and behavior of ash-forming constituent from biomass and coal during combustion by advanced analysis techniques, description of the mechanisms involved like mineral transformations, volatilisation and ash viscosity - comparison of experimental and analytical results with support of the description of the involved mechanisms - establishment of test procedures and analysis methods for deposit prediction and material tests - work out guidelines and a database for predicting the Influence of fuel on deposition and corrosion - fuels under consideration will be: C021 as reference case; different types of biomass like straw, energy crops and wood; wastes like sewage sludge and RDF. The work programme is divided into seven tasks. TASK 1 is the coordination of the project. TASKS 2 and 3 are the experimental approach in parallel to each other. TASK 2 concentrates on the experimental work on ash deposition, slagging and fouling in lab scale, pilot scale and large scale. TASK 3 concentrates on the experimental work on corrosion phenomena in co-combustion al high temperatures with new materials and coatings in lab scale and large scale facilities. TASK 4 includes the analytical work of the produced samples and the chemistry of corrosion and deposition mechanisms with regard to the chemical transformations of the ash forming constitutions from coal and biomass and the resulting products. TASK 5 concentrates on the comparison of results. Experimental and analytical findings will be evaluated with support of the description of the involved mechanisms. TASK 6 will establish and verify pilot scale test procedures and analysis methods for prediction and material tests based on the work in the above tasks. Finally in TASK 7 the synthesis of results will end up in application guidelines for predicting the influence of fuel on deposition and corrosion. Expected achievements The main achievements of the project, will be summarised in task 7, based on experimental and analytical evaluations, to provide test methods and prediction tools for slagging, fouling and corrosion to achieve a secure and widespread implementation of a variety of biomass types in large scale power plants.
