Carbon dioxide footprint reduction can be reached by switching fossile combustible consumers to biogenic fuels. Using biogenic fuels, mainly cellulosic ones, requires burner replacement and most often a complete change of burning process by introducing pre-burning chambers. The boiler response is also to be studied because the changes in flue gases composition, debits and temperatures. The paper analyses the necessary burning installation retrofitting for the case of switching a local boiler from gaseous fuel functioning to cellulosic fuel functioning (sawdust or pellets). It is presented a calculation method for boiler functioning verification (determining the functioning parameters considering an existing boiler used in other than nominal conditions) with the aim of determining the parametrical and performances variations when using other fuels. The nominal functioning regime, for witch there are available experimental data, is used to validate the model and the computational program. Conclusions are drawn regarding the possibility and results for retrofitting regional heating boilers from gaseous to biogenic fuels.
