Solid Fuel Combustion

Background:

It is expected a significant increase in biomass contribution to heat and power production, especially in small- and medium-scale systems in the following years. However, particulate matter (specially < PM1) and NOx emissions pose still a challenge in these systems, where post-processing techniques become too expensive. Detailed model-based design and optimization techniques offer the possibility of developing CHP technologies with higher efficiency, lower emissions and more flexibility. This includes direct combustion of biomass, but also indirect technologies, i.e., combustion of products (gas and/or liquid) derived from other biomass conversion pathways such as gasification, liquefaction or pyrolysis. To this end, deeper knowledge of the chemical kinetics and their interaction with transport phenomena for such processes is yet required, together with the inclusion of more challenging feedstock, which can lower costs and increase flexibility.

 

Objective:

To gain a better understanding on thermochemical conversion of solid fuels to contribute to the development of more flexible, cleaner and efficient CHP (Combine Heat and Power) systems.
