Abstract

Modeling of methane combustion in air carried out in environment modeling of chemical processes
software package Process Informatics Model (PrIMe). To investigate the methane combustion in
air in a program PrIMe was chosen mechanism GRI 3.0, which describes burning of methane and
other hydrocarbons (acetylene, propane). Kinetic mechanism GRI 3.0 describe the reactions taking
place at the molecular level, which deals with the order in which communications are broken or
formed. The mechanism chosen from base of the PrIMe program consists of the 309th reaction
and 53 reagents, and also for modeling of burning Plug Flow Reactor (PFR), the reactor of ideal
replacement, has been chosen stoichiometric mix of burning of methane in air. Modeling methane
inlet combustion air at a low pressure can be seen that almost no chemical reactions occur, but with
increasing temperature the reaction proceed faster also can be seen that the fuel in the pyrolysis
of nitrogen containing radicals leads to the formation of nitrogen oxides NOx
