Experimental study on the uniformity of velocity distribution of rectangular burner outlet of hot-blast stove

The flow in the burner is impacted by many factors, including the big bulk of the modern hot-blast stove, complex pipeline and too many valves. The length-width ratio of internal-combustion hot blast stoves is so high that non-uniform velocity distribution is easily brought forth along its length. Considering a real burner, a 1:5 scale model is established in this paper. The impact of the deflector on the velocity distribution of the nozzle exit is analyzed in the experiment, providing a basis for practical engineering design.
