Abstract

It is well known fact that appropriate organization of furnace aerodynamics can influence burning stability. Therefore, improving aerodynamic characteristics of the furnace is a main task in elaborating the boiler construction. For this task experimental study of three-dimensional burning flame dynamics should be performed. In this work turbulent combustion of natural gas in fire-tube boiler was simulated by means of the ANSYS Fluent software. The subject of studying was: complex of characteristics with space-time fields of the aerodynamic structure, range and aperture angle of the flame, pressure distribution, turbulent intensity and quite a number of other operation factors. The numerical computation results display the processes within the fire-tube furnace. Inertia of fuel-air jet at the furnace entrance provokes formation of axisymmetric scorching vortices, circulating to the burner slot. The article provides a method for predicting the vortex formation and evaluation of its integral characteristics, including the effect on the aerodynamics and heat transfer processes.
