Title: Improvements in means for controlling the air supply to furnaces
IPC: F23K3/12
Filed: 1936-04-09
Abstract: 469,974. Controlling air supply to furnaces. AMERICAN ENGINEERING CO. April 9, 1936, No. 10471. Convention date, May 18, 1935. [Class 51 (i)] In underfeed stokers of the kind provided with tuyere blocks, the air inlet to each tuyere block is provided with automatic damping means. As shown in Figs. 2 and 3, each tuyere block 10 carries a pair of pivoted dampers 31, 32 connected by a tie member 33 and the damper 31 has an arcuate portion 35 which engages with the rear end of the tuyere block. Air passes to each tuyere through the passage 40 formed between one of the dampers 32 and a damper 31 of an adjacent tuyere block. Should the thickness of the fuel bed above a tuyere decrease, an increased flow of air through the passage 40 causes an increase of the differential pressure on the inner and outer surfaces of the two dampers controlling the passage 40 and the dampers tend to close the passage 40 whereupon combustion decreases and the thickness of the fuel bed will build up and return to normal causing the flow of air through the passage 40 to decrease and the dampers to open again. The air passages between the tuyeres are divided by diverging ribs. Fig. 5 shows a modification wherein each tuyere block 42 carries a single damper 43 pivotally mounted in a recess and having an arcuate portion 47 which abuts or is slightly spaced from the wall 49 of the recess. The inlet passage 19<1> of each tuyere block is restricted at 48 and increased flow of air through the passage causes the damper to close. In the modification shown in Fig. 8, the dampers 62 are formed of two resilient portions which abut at the centre of the arcuate portion 61 which engages with a slot 60 in the tuyere. Springs s<1> tend to hold the dampers open. The dampers 72 shown in Fig. 10 are of arcuate form and have their inner ends weighted at w<1>. In another form each tuyere block is provided with a pair of damper elements arranged side by side. Instead of mounting the dampers on the tuyeres they may be mounted on frames 91, Fig. 14, having apertures adjacent the tuyere inlets and controlled by dampers 98, 99 of the kind shown in Fig. 2.
