The progressing development of industry and the associated increasing environmental pollution create the need for the intensification of combustion processes and the implementation of increasingly stringent environmental protection standards. Therefore, an intensive progress in scientific and research work is observed, and studies with the use of numerical methods are becoming an indispensable element of experimental research, enabling the optimization of combustion processes with the simultaneous evaluation of ecologic effects and, as a result, the development of new designs of burners and special, low-emission combustion technologies. This article presents possibilities for the numerical modelling of combustion processes and gas dynamics in heating furnaces. The chemistry of the combustion process was modelled using the software CHEMKIN version 4.02, while the gas dynamics of flue gas flow in the combustion chamber was modelled with the program FLUENT. Numerical computations were performed for both the experimental chamber and real facilities, namely a pusher furnace and a sheet hardening furnace.
