An internally circulating fluidized bed (ICFB) was applied to investigate the behavior of refuse derived fuels (RDF) incineration. The temperature distribution along bed height was measured by the thermocouple and the pollutant emissions in the flue gas were measured by Fourier transform infrared spectrometry Gasmet DX-3000. In the tests the concentrations of the species CO CO2 HCl N2O SO2 were measured online. The experimental results showed that the RDF could combust steadily in the fluidized bed. The concentrations of the CO HCl N2O in flue gas were higher than the values of national environmental standards.

Abstract The 40 MW Strongoli power plant, located in the Calabria region of Italy, produces power from 100% biomass sources. The combustion of wood biomass, exhausted olive residues and palm kernel shells, occurs in a sand-filled, Circulating Fluidized Bed (CFB) combustor. Operational experience with the unit dates back to 2003. This paper describes the optimization of the boiler in order to minimize erosion on internal surfaces and structures. Detailed three-dimensional, transient, multiphase gas-solid flow fields were computed and are presented. Details of the complex geometry include the combustion chamber, cyclone, cyclone dipleg, seal pot, fluidized bed heat exchanger and cyclone outlet structures including suspension tubes. The gas-solid flow was computed using the commercially-available software package Barracuda, a CFD software based on a unique Eulerian-Lagrangian formulation that was essential to the success of the subject work. Both instantaneous and time-averaged results were obtained. Results were validated against operational erosion experience. The validated model, in turn, was utilized to redesign various components of the boiler, optimizing both erosion characteristics and performance behaviour of the system. The redesigned unit was commissioned in early 2012.
