Boundary conditions used in the CFD simulation.

Part of the computational domain	Boundary condition	Boundary condition details
Inlet (flue gases from furnace)	Velocity inlet	The velocity of the air was 0.3 m/s. The ambient air temperature was 30.1°C, while the heated air from the combustion chamber (flame tip temperature) was measured and inputted from the experiment.
Outlet	Pressure outlet	The gauge pressure was assumed to be zero.
Hot plate	Wall	Stainless steel material was assigned to the hot plate.
Brick wall	Wall	The brick wall external temperature was assigned 30.1°C (which is the same as the ambient temperature).
Furnace internal wall	Wall	Brick material was assigned to the furnace internal walls.
