Where are the furnace heating holes????
Thread Content
I’m new to this field; I’m currently involved in coal preparation work, and soon I’ll move on to coking. I’ve read some books on the structure of coke ovens, and I understand most of their components, but I’m not sure where the oven drying holes are, how many there are, and which expert can help me explain the flow of gases during oven drying? Thank you. . .
I’m also a newcomer... The furnace holes are located between the coal loading ports on both sides of the coke oven and the furnace door, at a few layers below the top of the carbonization chamber; they can be barely seen from the coal loading ports. It’s not easy to locate these holes in an operating coke oven, so one can ask experienced workers on site for help. Loveliness: The gas flow path during heating is roughly from the carbonization chamber – to the combustion chamber – to the regenerator – to the small flue – to the waste gas tray – to the smoke distribution ducts – and finally to the chimney
The furnace drying holes that you are discussing are likely the same as the drying pores; after the furnace is dried, before it starts operating, special tools must be used to plug these pores with brick plugs. This is an important step in preparing the coke oven for operation under hot conditions. After it has been in use for some time, graphite that accumulates on the bricks as a result of the coking process usually makes these pores no longer visible. The friend on the second floor missed the process of flow from the combustion chamber through the inclined flue and then into the regenerator; everything else they said is correct.
On the topmost layer of bricks in the carbonization chamber, there are three at the position below the rising pipe, on the machine side, and below the middle coal feeding port; there are five from the coal feeding port on the coke side down to the furnace tip. Three of these are used for coal feeding, while two are not used (in some coke ovens, the rising pipe is located on the coke side). The airflow for heating the furnace flows from the fire bed --> carbonization chamber --> heating holes --> combustion chamber --> vertical flue --> inclined flue --> regenerative chamber --> small flue --> exhaust gas tray --> branch flues --> main flue --> chimney
