Prevention of Section Reduction of Stand Pipes

AbstractIn the stand pipes, which are the only evacuation point of the raw gas released during the high temperature coking of the coal, the section reduction occurs due to the carbonization and the problem of degazing of the raw coke gas is experienced. This leads to an increase in the internal pressure of the raw gas in the furnace and emissions to the doors, which are the weakest points for sealing. It also leads to energy losses depending on the amount of leakage. The raw gas passing through the vertical chimneys is 900 degrees and it is isolated with fireclay bricks to protect the metal parts. In this improvement, high-alumina castable mortar is used instead of fireclay bricks. This has resulted in a reduction in emissions and maintenance costs.
