ABSTRACT

The paper presents an analysis of the possibility the computer modelling of
combustion
to be used as a tool for control of the combustion process in industrial
boilers. The
analysis is based on computer simulation of two types of industrial boilers
under
different operating conditions: PTVM 100 (Reconstructed) hot water boiler
and PK
35
steam boilers. The specialized software developed is based on 3D transport
equations,
k-e turbulence model, eddy-dissipation combustion model and discrete ordinate
method
for the radiative heat transfer.
The results obtained demonstrate the possibility of analyzing and controlling
the
combustion process through the computer simulation of the process under
particular
operating conditions.
It is shown that computer simulation of the combustion process is the best, if
not the
only way to analyze and control the process in real time, independently of the
operation of a boiler.
