Oxy-combustion of agro and wood biomass in a fluidized bed
Czestochowa University of Technology, Faculty of Mechanical Engineering and Computer Science, Institute of Thermal Machinery, al. Armii Krajowej 21, 42-201 Czestochowa, Poland
Present trends in the global energy sector effectively drive the development of technologies using renewable energy sources and the improvement of combustion technology towards increasing its efficiency and removing environmentally harmful flue gases. One solution is to replace fossil energy sources with renewable sources, including biomass. The degree of biomass utilization depends on the size of resources and processing technology. There are more and more different types of biomass on the market. There are many technologies for its energetic use. In recent years, fluidized combustion technology has been considered as one of the main directions of development of professional energy in the world. Many units in the world in fluidized combustion technology use as primary or supplementary fuel: sludge, wood waste and biomass, as well as municipal waste, etc. Fluidized bed boilers also allow the implementation of the dynamically developing oxy-combustion technology, which perfectly fits the prevailing trends due to the key advantages of increased energy conversion, as well as the possibility of direct sequestration of carbon dioxide. During experimental research, the mass loss of biomass pellets of various origins was analyzed in an oxidizing and inert atmosphere in a two-phase flow with the use of inert material. The obtained results allow to state that the large variety of biomass offered by suppliers requires a thorough knowledge of its properties and determination of its impact on the process and installations when used in the power industry.
