Control of moisture in coal fed into the furnace
Thread Content
In rammed coke ovens, the moisture content of the coal fed into the furnace is kept between 9% and 11%. How is this moisture level controlled? Our factory relies mainly on people’s intuition, so the moisture level is not very stable. Are there any better control methods?
Control the water flow based on the coal flow, with automatic control
Could you give a brief introduction to the process? The flow rate of coal can be considered constant.
I would like to ask, where is the water supply pipe usually installed?
10.5, don’t you have any process control for coal washing?
10.5 Moisture content – don’t you have any control over the coal washing process?
This is a coking plant, not a coal washing plant, so there is no control for coal washing processes.
The water flow is controlled based on the coal flow, via automatic control; even if the coal flow remains constant, the moisture content in the coal can vary, so the amount of water added should be adjusted accordingly. How exactly is it controlled? ?
Based on experience, the water supply pipe is generally placed at the outlet of the crusher.
We keep the moisture content of the coal fed into the furnace between 10% and 13%; when it falls below 11%, we activate the mist-type water spraying nozzles located after the crusher.
