Abstract

The invention relates to bath furnaces and can be used in the glass industry for melting glass and melting other materials. The invention allows to intensify the heat exchange between the flares and the melt, improve product quality, and increase the service life of the furnace. The furnace contains a bath of 1 rectangular shape with a melt 2. On one end side, a loading frame is attached to the bath, and on the opposite side, a production channel. Above the bathroom side walls and end walls are installed. In the staggered side, burner devices 8 are installed, including burners and burner stones. The furnace on the side of the loading pocket is connected to the chimney by the ducts. The burners are installed with their tilt angle to the horizontal cuL 5-1 о at the distance of the center of their outlet openings from the surface of the melt, equal to (0.2oi + 0.5) D, and with a step equal to 0.51-0.65 width furnaces, where oi is the angle of inclination of the burner devices in degrees; D is the diameter of the outlet openings of the burner. 2 Il. i (C O 0 about 05; About Fig. 2

The invention relates to baths (0.2ot-0.5) 1), and a step to 0.51 flame furnaces and can be used 0.65 times the width of the furnace, where about is the angle of inclination in the glass burner industry; D - diameter

The purpose of the invention is the intensification. Initially, the optimal heat exchange was chosen, the quality of the forward angle of inclination to the horizontal axis was increased.

Ducting and an increase in the service life of 5-10 ° peeks from the conditions of the maximum range of a single floor. Figure 1 shows a furnace, a plan; Noah jet. This angle is derived from

Noah forms with melt 2. With one torus least squares method. The optic side of the bath was attached to the smallest found angle of inclination of the axis of the loading pocket 3, from the opposite-relique device 7.5 ° with the error - working channel 4. Above the bath 1.5%. At the maximum long-range, the side 5 and end face jet lengths of the loss wall 6 and the arch 7 are installed. In the side wall pressure along the axis of the jet, taking the staggered order, the smallest value is set. Reject

side of the boot pocket together-the square of the angle. Given the error

with exhaust channels 9. approximations choose the angle of inclination

The proposed oven works as follows - 25 ° within 5-10. shimm way. Then for a given optimal

The bath 1 through the loading pocket of the inclination of the torch axes is determined by 3 continuously feeding raw material, the optimum relative height spreading along the van position of the outlet openings of the burner plate. In the melt 2 under the action of Q x devices (burner stone) . Heat is chemical and other processes to prevent cooling. The finished melt of the drain is not yet mixed and does not enter into the working channel 4, Heats up the melting of high-temperature flames and gas at the roots of the flares and stabilizes the surface of the flares and stabilizes the surface of the flame and the combustion at the expense of more intensely directed across the furnace. High-temperature kiln suction flares create by burning natural gas or gases to the lower part of the fuel plume burners with burning devices 8, burning devices need to be spread. Burning devices create a setting as high as possible above the surface-burning flares and they are adjusted by glass melt while maintaining a length equal to width kilns Structuring patterns of flatness. In the case of combustion of fuel on the basis of experiments on hydraulics, the fuel lifts under arch 7, and the model moves in compliance with all law C. along with and removed through modeling holes it is found that ground channels 9 ., ic stylishness is preserved if the distance is due to the fact that the burner from the center of the outlet openings of the go- device is installed on the furnace in the shaft-reel devices (burner chamber order according to its optimum) to the surface of the melt is equal to the parameters (pitch, height and angle of slope- (0,2ob + 0,5) D ,, on), create ts conditions for implementation

full coverage of the melt surface with flat torches. When reducing the pitch to less than 0.5 kiln width, flat streams coming from opposite sides collide with each other and sharply turn upwards towards the roof. In this case, the arch can overheat, the glass melts underheat in the place where the jets collide due to the formation of a stagnant zone above the melt surface and the appearance of areas uncovered by torches between adjacent burners. in the central part, and then at the roots of the torches.
