F96/y/04 - Biofuels devolatilization and char combustion characterization with the IPFR
Authors: G. Bonvicini, G. Coraggio, M. Faleni
Publication date: December 2013Open Information
Related programme: IFRF Solid Fuel Database

The devolatilization and char combustion behavior of five biofuels were tested using the Isothermal Plug Flow Reactor. The tested biomasses are: Black Pellet, Danish Straw, Lignin, Palm Kernel Shell and Softwood Pellet.
The IPFR is a 4 m long drop tube reactor, with an inner diameter of 15 cm, which allows to characterize the combustion of solid fuels in a temperature range between 900 and 1300°C, with a particle residence time between 10 and 1500 ms. Devolatilization and char combustion can be tested separately, under both conventional and oxy-fuel conditions.

This report gives an overall description of the Isothermal Plug Flow Reactor and of the applied experimental procedures, with the required pre-treatments, the IPFR operation and experimental matrices, and the post-processing operations. A more detailed and theoretical approach can be found in the recent IFRF report N. G27/y/01.


The results of the characterization of five biofuels are then shown, with a particular attention to the conversion trends versus residence time. All the results of the laboratory analyses performed on the samples collected from the IPFR are also shown, in five dedicated annexes. A comparison among the behavior of the tested fuels is also given, concerning their devolatilization and char combustion rate, and the amplitude of the experimental error.

 


F96/y/03 - Biomass characterization for co-firing applications: black pellets and torrefied palm kernel shell
Authors: E. Biagini, F. Barontini, G.Coraggio, M. Faleni
Publication date: November 2013Open Information
Related programme: IFRF Solid Fuel Database

This document contains the results of the characterization of biomass materials performed by IFRF in collaboration with University of Pisa and ENEL Laboratories. The tested biofuels, coming from Polish company Remak Rozruch, include a virgin biomass (Black Pellets) and the torrefied products of PKS (Palm Kernel Shell), processed to achieve three levels of torrefaction (10%, 20%, 30% of the volatile matter content).

The tests include fundamental (proximate and ultimate) and additional (heating value, physical properties, morphology) analyses performed in the above laboratories, as well as the advanced tests of devolatilization and char oxidation in the Isothermal Plug Flow Reactor (IPFR) at the IFRF research center.


F96/y/02 - Devolatilization and char combustion characterization with the IPFR of a lignin produced by steam explosion
Authors: G. Bonvicini, G. Coraggio, M. Faleni
Publication date: November 2013Open Information
Related programme: IFRF Solid Fuel Database

This report gives an overall description of the Isothermal Plug Flow Reactor and of the applied experimental procedures, from the required preliminary actions, to the IPFR operation and experimental matrices, and the post-processing operations. The results of the lignin characterization are then shown, with a particular attention to the conversion trends versus residence time.


G27/y/01 - Development of the experimental procedures for advanced biofuels characterization in the Isothermal Plug Flow Reactor
New methodologies for feedstock characterization
Authors: E. Biagini, G. Bonvicini, G. Coraggio, M. Faleni
Publication date: November 2013Open Information
Related programme: IFRF Solid Fuel Database

The aim of this work is to define the experimental procedures for testing solid fuels in the IFRF’s Isothermal Plug Flow Reactor (IPFR), which is an advanced tool for combustion related studies, and extrapolate the prerequisites and principles that could be in common with other advanced equipment. The aim is to provide qualified data for quantitative prediction of operational/design parameters of industrial-scale combustion systems through Computational Fluid Dynamics simulations. Uniform and reliable data will be also inserted into the IFRF online Solid Fuel Database (SFDB).
