Stainless steel casing with a gas channel to eliminate fire brick question

Peeling mud cracks between the blocks are more loose, especially brick road staggering gas, coke oven daily production management to a lot of inconvenience. Coke oven put into production soon after the gas was found in brick tiles around the outside seam gas brag, causing brick road outside the gas fire. In particular coke combustion chamber side of 48,49,52 and 53 is more serious. Despite repeated wiping make still effective. Branch after the extended approach with the initial results can still be a few days, but brick gas channel at high temperature, severe high-temperature oxidation of iron pipe, causing gas brick road congestion, the problem is not resolved due to the frequent fire demolition of pipes, resulting in 516 No moving orange brick, no mud cracks between the blocks, so that increase of blow, causing burning column bending furnace 49, the curvature of more than 50mm fans. Operating experience has shown that to solve the problem fire brick gas leak channel is the key to improving the material and appropriate increase in branch length of branch gas channel temperature is generally brick 75O ~ I100 ��. Chrome silicon steel (Cr25Si2) is characterized by good oxidation resistance, better adaptation to temperature fluctuations, can be used for heat-resistant temperature is higher than 1050'C components used. To this end, we use chrome silicon steel for the branch from the leather jacket is not only not oxidize, and long service life. Brick Road, an inner diameter of the gas changes, in order to block the gas channel after the change not affect the diameter of burner temperature, we selected the 70 �� 4.5mm, 100 �� 4.5mm two types of chrome silicon steel became resistant adjustable chrome silicon steel casing. A level of I-66 brick oven flue gas channel for a distance of the front line is 627mm, the second brick from the front line sewing 518mm, tube length as long as more than 518mm, less than 627mm, can play a sealed 1 , 2 brick joints for rejection. We will set the total length of casing 650mm (with oven column thickness). The structure shown in Figure l. Figure 1 Bin casing structure 22 No. 4 empty coke oven gas collector insulation replacement in light prince Yu Yin Xu 2 hair casing requirements supporting the casing pipe installed to indicate prince Yu weld smooth and without trachoma, concentricity good. Insert before the first brick Road clean up the gas,[link widoczny dla zalogowanych], the gas along the brick road around his hand over a good clay, while the casing wall to a more viscous mud Muddy, must be covered with mud, and then inserted into the casing. Also inserted into the most shallow 520ram, and turn the sleeve, so that mud brick gas filled the whole road. Along the tube wall exterior Qianzi hit real smooth. Finally, the original branch of fine asbestos rope wound into the casing can be real hit. The structure shown in Figure 2. After nearly a year of use of that branch with a heat-resistant chrome silicon steel jacket,[link widoczny dla zalogowanych], the elimination of the brick gas leak Road, played a protective role of iron, not only reduces the energy consumption, but also significantly reduce the workload of hot repair . Chrome silicon steel will heat soil compaction bang expansion, and as one, in this temperature range can not afford to skin, no oxidation,[link widoczny dla zalogowanych], thus basically eliminating brick fire leakage phenomenon of gas channel.
