Mathematical modelling of physical and chemical processes of coal combustion in chamber furnaces of boiler aggregates based on the package of applied programs FIRE 3D

Engineering method for thermal calculation of the vortex combustion in dead-end fire-tubes

“…However, the basis of most known approaches is the finite element method, which involves the installation of special software and requires a significant amount of time for calculations and setting the initial and boundary conditions [2]. This makes impossible using of such techniques for optimization tasks requiring the calculation of a large number of options for the design layouts.…”

“…Nowadays computer-aided simulation with the use of approved computer aided engineering software became widespread solution for complex problems of combustion aerodynamics optimization [2]. Computer simulation can reduce designing expenses by excluding costly field experiments of the production cycle.…”

Computer simulation of vortex combustion processes in fire-tube boilers

“…Full-scale multiple-factor experimental research of described three-dimensional vortical turbulent combustion is quite expensive. Therefore, nowadays computer simulation with the use of wide approved application packages is used to research furnace aerodynamics [4]. For example, burning turbulent vortex flow was simulated in [1,2,5].…”

Numerical studies of the combustion of fuel oil in the boiler furnace at reduced load

“…Uneven and erratic movement of gases in the furnace, on the contrary, leads to the opposite result and can cause excess of allowable local heat loads, especially at low load operation of power boilers, so it is necessary to provide combustion processes depending on the scheme and the combustion conditions. Most effective for this use of numerical methods of three-dimensional modeling [1,2].…”
