The calculations were performed Received in revised form 21 June 2016 using the ANSYS FLUENT commercial code. The swirl burner operates with the secondary air swirl angle of Accepted 28 June 2016 50°. The boiler is supplied by outermost sets of mills – the mills and either the bottom or the upper burners. A Available online 8 July 2016 proposal is made to change the secondary air swirl angle to 45°. Therefore, four cases of the furnace chamber op- eration are simulated: the furnace is supplied by either the bottom or the upper burners with the secondary air Keywords: Numerical simulations
