Characterization of wood and black pellets combustion for clean energy generation

Abstract :

The themes of my research are to quantify and compare the combustion characteristics and the associated polluting emissions of natural wood pellets and roasted black pellets.
By controlling all the combustion parameters (primary and secondary incoming air, pellet flow, boiler power), the main objectives are to:
- Quantify and compare the combustion characteristics of natural wood pellets and roasted pellets on a well-controlled combustion test bench.
- To measure pollutant emissions using physicochemical analyzers and by in-situ laser diagnostics in the combustion chamber and in the chimney.
- Assess the technical-economic advantages of the two types of pellets across the entire value chain and offer professional advice to heating engineers and combinators on the most economical and environmentally friendly use of biomass pellets.
