Set point for injecting coal tar in blast furnace
Set point for injecting coal tar in blast furnace
(OP)
I am an instrumentation engineer.
We are doing the engineering for injection of coal tar into tuyeres of a big blast furnace. This is slated to bring down the coke rate in the furnace.
We know that about 30 to 50 kg of coal tar per tonne of hot metal is the norm.
But, the set-point for tar injection (in terms of flowrate) must vary with the blast-furnace parameters, somehow.
Or, should it to be at a constant rate?
Will anyone tell me what or suggest a link / reading material?

It varies based upon the current BF operation (stable or not and output rates desired, higher injection at higher output rates)
