Safe co-combustion and extended use of biomass and biowaste in chp fb plants with accepted emissions (FBCOBIOW)

Obiettivo

Objectives and problems to be solved :To extend combustion of biomass waste in high-efficiency FB boilers instead of land filling. This objective serves strongly also the candidate countries. Sub-objectives are:
a) to create basis to replace fossil fuel partly by biomass in large Polish CFB plants
b) to strengthen basis to deliver small FB boilers for difficult agricultural waste to Eastern European countries,
c) to find ways to burn demanding biomass waste as household waste and meat and bone meal (MBM) together with traditional fuels without operational problems obeying the emission limits of the new directive
d) to improve prediction potential for operational problems and modelling tools for emissions of toxic elements
e) to improve an on-line analyser to a sensor of corrosive flue gases, f) to reduce formation of fine fly ash by chemicals, and hereby emissions of toxic elements bound in small particles. Description of the work: The work carried out by two boilers manufacturers one power company, manufacturers of analysers and chemicals, well-known research centre and well known universities in combustion research includes four main research areas:
1. To strengthen markedly the basis to replace a part of fossil fuel with biomass in Polish CFB plants. This component includes selection of Polish biomasses, combustion testing and optimisation, and emission reduction with 50 kW CFB, study on feeding properties and finally a feasibility study. Advanced analytics will be used to fly ash and flue gas characterization.
2. To enable safe combustion of demanding and risky biomass waste: meat and bone meal (MBM) and household waste safely together with coal and wood in modern FB plants. This component includes combustion tests with BFB and CFB reactors of 0.02 0.1 2, 4 MW and full scale tests, determination and solution of operational and emission problems. Advanced analytics will be used to fly ash, flue gas and deposit characterisation.
3. A study assisting a boiler manufacturer to improve fuel flexibility in small biomass fired FB boilers for Eastern European markets. This study includes pilot- and full scale testing, advanced analysis, modelling and probing tools.
4. Developing tools assisting in minimising operational problems and emissions in FB boilers: A real time sensor will be developed to detect corrosion risk from flue gas composition. Development includes planning construction, laboratory tests and tests from pilot-reactors. Modelling and simulation tools for toxic element distribution and particulate formation will be improved Expected Results and Exploitation Plans:- Suggestion to biomass for a feedstock for large fossil fuel fired Eastern European FB plants - Means to burn household waste and MBM with high share in effective FB's - More flexible small FB boilers to Eastern European markets - Better means to obey the existing emission limits - Monitoring system to prevent fluidised bed (FB) boiler damages - Better prediction and modelling tools for toxic metal release at FB conditions - Guidelines to burn the studied fuels
