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

Abstract: Abstract. In article the method for predicting the vortex formation in the dead-end furnace is described. Mass and heat balances of environment in the vortex are calculated using the computer simulation with ANSYS Fluent software. Engineering approach for quantitative analysis of singularities in the reversible flame is proposed. Assessment of vortices integral characteristics, including effects on the aerodynamics and heat transfer processes in dead-end furnace, is given.

“…For the described layout there are approximate equations of quasi-one dimensional method of recirculating fraction calculation applied to the combustion chamber with reversed flame [10]. In order to estimate the impact of the recirculating flue gases on the integral boiler performance characteristics in paper [10] is suggested to use the relative value of the recirculation flow (r). It can be defined as volumetric flow rate of the recirculating flue gases divided by total volume flow through the furnace:…”
