This week, the IFRF Handbook publishes two Combustion Files relating to the characterisation of solid fuels in vertical reactors.  The IFRF has a well established approach to characterising solid fuels in its Isothermal Plug Flow Reactor (IPFR).

This reactor was first introduced in CF135 and a description of its use for the measurement of pulverised coal High Temperature Volatile Matter release was detailed in CF183.

Today we add CF184 and CF231, which describe the determination of char burnout kinetics and the evolution of fuel nitrogen respectively, both using the IPFR approach. The Combustion Files are entitled:

CF184 – How may the IFRF Isothermal Plug Flow Reactor be used to measure char Burnout?

CF231 – How may the IFRF Isothermal Plug Flow Reactor be used to characterise the fate of fuel nitrogen for pulverised fuel?

These Combustion Files have been authored by Simon Leiser of the IFRF Research Station. My thanks to him and to Peter Roberts of IFRF for refereeing these Combustion Files.

IFRF members may read or download the new Combustion Files at www.handbook.ifrf.net, by selecting ‘New Combustion Files’ after accepting the disclaimer screen.

As mentioned above, additional information on the IPFR approach to solid fuel characterisation is already available in the Handbook. This and other Combustion Files on similar topics may be identified by undertaking a Handbook Search using keywords such as ‘IPFR’ or ‘characterisation’. A selection of these Combustion Files is also open to non-members of IFRF wishing to access the general principles behind fuel characterisation techniques.
