Actually from my Blast Furnace experience, I can say that too much air is a bad thing for temperature, as in a Blast Furnace the air is preheated in stoves, if the stoves are not sufficiently heated a cold blast can freeze a blast furnace, Apparently in a coke or charcoal forge you need just enough air to react with the available surface area of red hot coals, any more air serves only to cool the furnace by dilution,
The correct process apparently is to use some form of temperature measuring device and start "Blasting" with a small flow rate of air, wait until the temp stabilizes, then slowly increase air flow until the temperature starts to drop, at this point you have a maximum air flow setting, that should not be exceeded and a rough idea of how much heat is available at what "Blast rate"

Whatever it is, do it today, Tomorrow may not be an option and regret outlasts fatigue.
