Abstract (en)
[origin: EP0421182A2] In dryers with gas heating, it is a particular problem uniformly to mix the combustion gases produced with the burner with the treatment air which is circulated in the circuit. In order to achieve this, a special construction of the air mixing device is envisaged, which consists of three parts arranged one behind another, the treatment air being in each part of different construction in each case deflected to the centre of the treatment duct and in this connection mixed with the air flows which originate from the sides. It is advantageous, firstly by means of a funnel-shaped air mixing part and then by means of such with sheets arranged parallel to one another, which are first arranged vertically and then transversely thereto, to create swirling in each case. <IMAGE>
