Graphite in the coke oven carbonization chamber
Thread Content
There is a considerable amount of graphite formed on the furnace walls of the coke oven carbonization chamber. What are the common causes of this?
The Q&A is over, friend from Tangshan! The rapid growth of graphite is related to the following: 1. High temperature in the furnace roof area. 2. The coal fed into the furnace has a high volatility content. 3. High pressure in the gas collection pipe. 4. The standard temperature is high. The high temperature in the furnace top space is related to the size of that space as well as the way the coal is loaded; a high pressure in the gas collection ducts also results in a longer residence time for the raw gas in that space, thereby contributing to higher temperatures. The furnace walls of old coke ovens have a layer of smooth, protective graphite that helps with sealing; however, if this layer is too thick or uneven, the current required to push the coke increases, and pushing the coke may even become difficult. The reasons for the accelerated wear of this graphite need to be identified one by one. To clean the graphite, the furnace can be emptied, a compressed air cleaning tube can be attached to the coke pushing rod, or a graphite removal device in the form of a \"cap\" can be installed on top of the rod; alternatively, manual cleaning using a long pole shovel can also be employed.
